How do you hook up two amps to two subs

the turn-on lead runs between the amp and your receiver. if you don't get the right voltage at the amp, then you know to keep looking for a wiring problem. This is an article about how to install a multiple-component, high-end car audio/sound system. if you just want to hear a bit more bass than your regular stereo speakers can put out, you can get what you need with an efficient 6-1/2" subwoofer driven by as little as 50 watts rms. amps have a big factor on sound quality, i have a pair of infinity kappa component that are really bright and distorting i was told that the low end rockford amp i'm using should be replaced for a higher end amp. the answer to all those questions was yes and your amp still doesn't come on, then perform the following test:Remove the in-line fuse on the power cable. generally speaking, a 2-channel amp is inappropriate for driving a subwoofer. just try different positions every few days until you're happy with what you hear. if your amp now comes on, it means the turn-on lead was wired to the receiver's power antenna lead by mistake and needs to be correctly re-wired to the remote turn-on lead connection.: what wiring do i need to hook up my amplifier? this is so you can combine multiple subs together, in various configurations, and achieve a total impedance that your amplifier can handle. check out this article, and if you need any help upgrading your system, give us a call at 1. in general, the larger your subwoofer and the harder you want it to hit, the more power you'll need. bass boost is another kind of eq or tone control dedicated usually to one particularly low note. aftermarket receiver — you might want 200 to 300 watts rms of power for your sub. you also may find that the bridged channels don't produce enough power for strong bass.» how much air space do i need around my amplifier? to: install a subwoofer and amplifier in your vehicle - part 1 of 2. it takes a 4-channel amplifier to drive 4 speakers, one speaker per channel. and 2 sub 8" 150 rms (300max) in parallel to a mono amp with 300 rms at 4ohm output? for power, you'd run one fused (100a) 2- to 4-gauge wire from the battery to a distribution block.: amplifiers generally do not include the wiring necessary to hook them up. to wire two dual 4 ohm subwoofers to a 1 ohm final impedance | car audio 101.: how do i fine-tune my amplifier's gain and bass boost settings? you should count on using more power for bass than you use to power all your full-range speakers. i would think this is a remote function of the head unit itself, but the sync mode was not even used for the last few days and the phone that it syncs with is not even here., if you can't achieve the tune you want using the tone controls available, maybe you should look into adding an equalizer to your system, like an audiocontrol eql, in order to tame those out-of-control frequencies. a short circuit occurs when a positive current-bearing wire makes contact with bare metal (like your car chassis).: in the event of an electrical mishap, you do not want a live wire stretching throughout your vehicle. a trunk-mounted amp requires longer power and signal cables, but is safely hidden and closer to rear speakers and your subwoofer. if those subs are the dvc 4-ohm models, you should wire each to its amp like this.: bridging combines two of an amplifier's channels into one channel, in order to get more power. or you can get an amp or powered sub with speaker-level inputs and use the high-level signal directly. low bass notes are power hungry, and the more wattage you feed them, the better they sound. are a few things to consider, though:How efficient are your speakers? two svc 4-ohm subs wired together will only be 8 ohms if they were wired in series, and you probably don't want to do that. if your head unit is lacking these extra outputs then there are several other options. as these components age the current draw can be even higher. by continuing to use our site, you agree to our cookie policy., three dvc 2-ohm subs get wired to a mono amp capable of driving a 1-ohm load like this." there are a few exceptions, but the vast majority of 2-channel amps can't drive loads lower than 4 ohms when bridged, and don't have enough power to drive more than one sub.: how many subwoofers can i hook up to my amplifier? it sounds like you have yours connected to a constant power source and it killed your battery. you won't need as long a ground wire because your grounding point should be close to the amplifier. b amps operate with each of their output transistors having current flowing through them only half the time, switching off when the signal's not there. but the more subs an amp is placed on, the less power it can give to each individual sub. the other end of the amp, you'll need speaker wire. in fact, you always want the power from the amp to be slightly higher than what the sub(s) requires; a 1000w amp will work well with a 7 or 800w rms sub.

How do you hook up two amps to one sub

check out "how do i fine-tune my amplifier's gain and bass boost settings? speaker location, extraneous road/car noise, noise damping material, and personal taste are factors that may affect how much power you'll need in your system.: this is a popular question, and one that's difficult to answer definitively. i put my subwoofer box in the trunk, will i be able to hear the bass? it’s basically splicing an rca signal into two circuits.: should i use a mono amplifier or a multichannel amplifier to power my subs? fast-and-nasty way to ballpark an amplifier's current draw is to divide the total fuse value of the amp by two. you use rca patch cables to send the signal from your receiver to your amplifiers. balance this equation against the amount of room in your vehicle. a 1-farad capacitor could potentially cost hundreds of dollars and not solve any power problems., you could connect two speakers to a channel of your amp (using speaker wire not rca cables), but you'd lose the ability to control the volume of each speaker separately, the front-to-rear fade control, and the power from the amp will get split in half by driving two speakers. turn up your amp's gain until you hear the music start to distort, then turn it down a little so it plays clean again. in a perfect world with a perfect amplifier, power output would double every time the impedance was halved. a convenient place to make these connections is behind the radio where all the vehicle's speaker wires are accessible in one location.» what wiring do i need to hook up my amplifier? if you do not use a distribution block then you will want to stack your ground wires so that the largest current carrying wire (usually from your largest amplifier) is on the bottom (closest to the ground point) and that your smallest current carrying wire is on the top (closest to the head of your grounding screw). turn up your amp's gain until you hear the music start to distort, then turn it down a little so it plays clean again.: what do i need to know about impedance when wiring subs to an amplifier? since there is only one wire you only need one ring terminal at the battery post and only one fuse holder for the audio system.-set the amp gain — turn the amp's gain down first, and then repeat steps 2 and 3. two 4-ohm voice coils in series make an 8-ohm load. if you don't hear any distortion, even at full volume, set the receiver's volume to ¾ full. you may completely drain your existing car battery and render it useless.: the benefits of hooking up two subs to a mono amplifier are the same as hooking up any other number of subs to a mono amp: you can push the subs with more power at lower impedances. that also means that dirt, crumbs, water, and other contaminants need to get cleaned off an amp if you want it to work properly and reliably. ab is a combination of the two, where the output transistors power-down a little when not in use, resulting in good sound fidelity and adequate efficiency (often 50%). if your amp does not have a good protect system, it could easily blow because of a silly mistake. i connect a 4 channel amp to two rear speakers two front speakers and a sub?, if you're asking if an amplifier's preamp outputs are live when the amp is turned off, then the answer is probably not. use the biggest but most appropriate wire in case you decide to upgrade your sound system. it also lets you run shorter cables from your receiver. if your amplifier doesn't have an onboard fuse, it might be a good idea to add that recommended fuse near the amp to protect it., you need to find out the reason fuses are blowing and correct that issue first., check the alpine manual for the ideal box dimensions for those subs to see if they're a proper match with the memphis box. series wiring will raise the load (resistance) that your amp sees, and parallel wiring will lower it. you have a 3000w amp playing three 1000w subs, but they really sound weak, then it's time to get more power. am readying to do my full install within a few days. most people in this situation would use two channels to drive the front speakers, bridge the other two for a sub, and leave the rear speakers connected to the receiver for the rear-fill sound. have two alpine type r's and i'm wondering if i can put them inside my memphis box that holds two memphis sr's and is ported. i need an aftermarket stereo to hook up my amp and sub? wire from the positive terminal of the amplifier to the positive terminal of one speaker. he figured out how to run it by the time he was two. why is it that my subwoofers sound louder with one amp then when i had two of the same ampliers hooked up? just make sure the power and ground are positioned properly throughout the process., you'll want four 4-ohm dvc subs rated between 183 and 366 watts rms. the "nominal" impedance rating of a particular speaker or sub is the value the manufacturer has asigned to it for the useful calculation and application of power. can i bridge my amp and run two in parallel? the ground cable from your amp firmly connected to the car's metal chassis with no paint or varnish interfering with a clean electrical contact?

    in addition to creating the articles and videos you find in the research area of the crutchfield website, these hard-working and talented people write the informational copy for the products on our website and in the crutchfield catalog. amp that is rated at 1000w rms (root mean square, or the average watt the speaker is intended to receive and play with) set for 1 ohm can power two 2-ohm subs rated at 500w rms. if they barely flicker, then your power is manageable, but if they almost go dark with each bass note, then it's time for more power.: rms wattage is a measurement of power capacity used for comparing and matching components together. if rated under, make sure your amp's level is not too high as you can damage the sub. those low notes would probably be the first ones to distort through those speakers when you turn up the volume later. with all the receiver's eq presets and tone controls off or set to flat. if you're using a factory receiver without rca outputs, you can get your amp's input signal from the factory speaker wiring, either behind the radio or from the rear speaker leads. you will be asked to supply the total rms wattage of your system, as well as the estimated length of your intended power cable. aftermarket head units provide this but it is recommended that you do not connect more than 1-2 components directly to it. i have a question, i have a emf 12" 2000rms subwoofer wired to 1ohm and i just had stinger 4 gauge 6000 series installed with a 175 amp fuse. our writers constantly research the latest products, technologies, and industry trends, so that we can bring you the most helpful information possible., the in-line fuse that comes with the wiring kit is there to protect the power wire and your car in the event of a short circuit., not knowing exactly what amplifiers, speakers, or subwoofers you have, or how they're wired together make it impossible to give advice on what may be wrong. and that sundowner amp needs 1/0-gauge power and ground wiring. why do i need to add an additional fuse at the battery?: what's polyester fiber stuffing, and how will it affect my subwoofer's sound? there are many products that claim to reduce ground noise, the best method is positioning the main power wire and rcas/4-channel amps as far away from each other as possible. last check, if you have and know how to use a voltmeter, while that remote jumper wire is still attached, measure the voltage at the amplifier's power terminal and remote turn-on terminal. because mono amps tend to be class d amplifiers, they are a good choice for powering subwoofers — class d amplifiers have a high power-to-heat ratio and excellent efficiency, which are exactly what you want when dealing with power-hungry low frequency signals. run a single 4-gauge power wire from your battery to a 3-way (or 4-way) distribution block next to your amps.: : bridging combines two of an amplifier's channels into one channel, in order to get more power. for sub amps, turn on the low-pass filter and remove anything that's not bass from the subwoofer's sound. the point on your car's chassis where you bolt the ground wire should be cleaned and scraped paint-free to ensure a tight electrical connection. other than the fade/balance issues (left rear sound coming from right front, for instance) the sound of the components is excellent. you really need to, do not get multiple batteries or capacitors. mono subwoofer amplifiers take two inputs, left and right, and combine them internally to form the monaural signal used for subwoofers. you'll be able to push your subwoofers with the mono amp's maximum power, without running at a dangerouly low impedance. if you're interested in custom fabrication and car audio installation be sure to check out what we have to offer. mono amp is 1100 watts rms @ 2 ohms and i have a wiring diagram for 4- 4ohm dvc subs in a parallel/series to a 2 ohm connection to the amp.» what are the benefits of hooking up 2 subwoofers to a mono amplifier? now, the amp does have a "thin blue wire" or turn on lead that isn't hooked up, but that's only because there isn't a cable for it on the radio? but if your amplifiers don't each have their own fuses, you definitely do need to fuse each amp's power line near the amp., there are limits to how low a speaker's impedance can be before the amplifier tries to put out more power than it can, over-stresses, and probably shuts down.: generally, it doesn't matter where on the box the port is, as long as the air coming from it can flow freely. check out the article on dual voice coil subwoofers for more information. comment below that "a 2 ch amp is inappropriate for driving a subwoofer ", is completely false and documented by millions of people and hundreds of audio component manufacturers. do i determine what gauge of speaker wire to run in my setup if the woofer is 2dvc 4ohm 2000 watt peak ? subwoofers come in a variety of impedances and even the number of voice coils. most 12 volt relays can supply up to 30 amps of current which is more than enough for all your turn on circuits. and i have a hifonics zeus 2400watt 1200rms amp to it but was thinking of buying another amp like the sundown scv 2000d for the emf sub can my 4 gauge with 175 amp fuse handle the sundown amp? even with one or two batteries, caps, or even two alternators, you may not produce the amps/volts that your cars original electric system + sound system require to keep it running and major damage can occur to your original electrical equipment because of lack of power. that jl audio e-series amp you mention is a 1-channel amp, so i don't know how it could be used with factory speakers. mono subwoofer amps, like the kenwood kac-5001ps, are stable down to 2 ohms, allowing you to hook up two 4-ohm subs in parallel. when the head unit is turned on the remote lead triggers the relay which connects terminals 30 and 87 together, sending a 12 volt signal to all of the electronic components. this type of enclosure is your best bet for driving your frequency response down.» how do i fine-tune my amplifier's gain and bass boost settings? for amplifiers that do not have fuse protection you should use a fused distribution block.
  • How to hook up two amplifiers 1 for sub & one for mids & highs

    an amplifier needs some open air space around it to dissipate the heat that builds up as it works, otherwise it will overheat and shut down. your amplifiers will be powering dissimilar speakers (subs, mids, tweeters, etc."2-ohm stable" does not mean the amp can drive a 2-ohm load with bridged channels — in fact it means it can't. this assumes your amplifiers already have built in fuses that are designed to protect them. if you choose to run your ground wires to one point you can also use a distribution block. time estimates do not apply to large or heavy items that require special. using the maximum recommended air space for a subwoofer better than less than the maximum. because most speakers are rated to 8 ohms, you can generally connect many speaker to one amp without any problems. i was wondering if i can run an amp from wall power to my subs in my room so i can have high quality music in my room. some amps have phase switch yet just reversing speaker connections changes phase.: one of the final steps in any amplifier installation is to set its gain properly. if it reads about +12 volts dc or more each, then your wiring is good but your amp is bad.: your car amplifier will draw a lot of current from your vehicle's electrical system, and therefore will need thick enough power wiring to ensure that the current flows freely, without resistance. for example, you could use a 4-channel amp to drive your left and right speakers with two of its channels, and drive a sub with its other two channels bridged together, saving you the need to buy a separate sub amp. this is not necessarily a bad thing if you have a 2000w rms amp and two 600w rms subs. i tapped off the left and right rear speakers but i am getting little to no joy out of the subwoofers. if you're installing two or more amplifiers, just add their fuse ratings together and install a fuse rated roughly equal to this sum. but if you already have an amp and it doesn't accept such a high level of input, you can use a line output converter to lower it to rca-level. some line output converters have level controls and yours may be set wrong. articleshow to remove a stuck cd from a car cd playerhow to install a car stereohow to install car speakershow to unlock your locked gm theftlock radio. the triangle-shaped woofers might be convenient if you're short on cargo space, since triangular boxes fit into places where standard boxes just can't go. not does crutchfield have plans to expand to oversea's market's ? mono amps have two sets of speaker terminals for convenience of installation: if you are hooking up two subs to the amp and using large-gauge wire, it gives you a place to attach the wires without having to trim them, appearing as if each subwoofer gets its own terminal. to install 2 amps with only 1xpreouts on headunit (mind the mess) 1of2. but if you've ever taken a peek at some multi-amp competition-style car audio systems, you may have noticed fuses at a third location — in a fuse block by the amps. if not can i just connect a sub and the rear speakers and have the front speakers still working even if they're not connected?: a well-made stereo amplifier that is stable to 2 ohms should be able to handle up to four 4-ohm woofers (two subwoofers wired in parallel to each channel). most car audio amplifiers boast a design flexible enough to keep them in the game as your set-up expands. you should also keep in mind that when two speakers are wired together, whether in series or parallel, they share the power given them evenly, one-half of the total to each.: do i need an aftermarket stereo to hook up my amp and sub? most subs are rated at 4 ohms, but 2-ohm, 8-ohm, and dual voice coil subwoofers have become commonplace, so it's easy to find speakers that will bring out the best in the amp you've chosen. this way, you can wire the subwoofer according to your system design and preferences. depending on how much stuffing you use, you can actually vary perceived box volume by as much as 30%. that you have your power and ground wires connected you'll need to give your amplifiers a music signal (usually the rca cables run from the head unit). if you stay within that range, your sub will perform as envisioned by its designer." as long as you stay within the recommended power range of your speakers, increasing power will always add richness and depth to your music. have a four door lariat ford f-250 (truck) but very limited space, i want to put some subs in but don't know what size and how to wire, and i need the back seats open. this is an important difference when using your amp to power multiple subwoofers, because you won't be able to bridge your multichannel, 4-ohm stable amp to power multiple subs that present less than a 4-ohm load. it may save you a lot of time and money." bridging means combining two amp channels together into one, in order to get more power.: since space is at a premium in most vehicles, it's important to find just the right spot to mount your amp. and if you can wire the subs together to present the amp a 4-ohm load, they can take the amp's full power easily as well. but, generally speaking, given adequate power, the two 10" subs will sound a little cleaner and punch harder because their combined cone surface area yields more sound pressure. do i need to get a smaller fuse to match the requirements? give us a call, and an advisor can talk through your bass needs to find the right sub for your vehicle. it would be foolish to run multiple wires through your door and dash to play multiple speakers with such low wattage. you series-wire two 4-ohm speakers, the amp will see an 8-ohm load., knowing precisely what make and model amp you're getting would help, and alternators are usually rated in amperes, not watts.

Car amplifiers FAQ

i have already installed powered sub in my trunk i want to add one more powered sub.. it's more difficult for your ears to determine where low frequencies come from than highs), bass is often transmitted in mono. are the benefits of hooking up 2 subwoofers to a mono amplifier? amplifiers usually do not by themselves affect tone, and play distortion only when either over-driven or fed distorted signals to begin with. this is my deciding vote, and i know you guys are the some of the best in the business. more subs = more cone surface area = more air moved = big bass! this is a simple way to split a single rca output into two rca outputs.» why do i need to add an additional fuse at the battery? trying to wire my subs into my factory 6x9s ive tied the wires from the 6x9s together with speaker wire that goes into the subs then another run of speaker wire from the subs to the amp and a remote jumper ive done it be4 and it worked pls tell me what im doing wrong. it doesn't need to be as thick as the power and ground wires (18 gauge should be fine)., it depends on which specific amp and which specific sub. i use a mono amplifier or a multichannel amplifier to power my subs? there are so many factors that come in to play — power, enclosure type and size, as well as your specific vehicle and your individual perception. however, we offer a number of amp wiring kits that can provide everything you need to send signal and power to your amp. instead, use a mono amplifier to power a 2-ohm load — two 4-ohm subwoofers, or 2, 2-ohm dual voice coil subwoofers, for example. sure your 4-channel amp can play them all without being so powerful that they damage the speakers.: the benefits of hooking up two subs to a mono amplifier are the same as hooking up any other number of subs to a mono amp: you can push the subs with more power at lower impedances. you should only use rms ratings when comparing and matching gear.: if you're installing just one amplifier, the fuse at the battery should simply match or slightly exceed the fuse rating of the amplifier itself. wiring works the same way as flashlight batteries; the positive end of one speaker is connected to the negative end of the other speaker.: the right answer to this question depends upon which subwoofer you choose. last wire you need for powering the amp is a turn-on lead." while most car audio amplifiers do come with their own fuses, these fuses are designed to protect only the amps themselves. there will be some screws once you take them off lift up on the panel and pull it out. you do not want to leave the turn-on lead jumped to the amp's positive terminal because that way the amp will never shut off, draining your car's battery dead. also carry small powered and enclosed subs that fit under or behind the seat. terminal 87 of the relay is connected to the electronic components remote turn on terminal. i was thinking about using a y shaped rca cable to connect the back door and dash speakers to 2 channels, front speakers to 2 channels and the last channel to the sub? i have a 2012 kia sportage lx and i jus bought a powered sub. one way to take advantage of this is to wire two 4-ohm speakers together in parallel, making a 2-ohm load, to each channel of your amplifier., without knowing exactly what amplifier you have, it's hard to make a recommendation about the subs. your patch cable should be long enough to reach the amp but not so long that it has a lot of slack and could become kinked over time., i wouldn't recommend it, and given the power specs of that sub/amp combo, you won't get the bass you're hoping for out of that sub.» what size power and ground wires do i need for my amplifier? they're less expensive and there's no need for the extra fuses when there is already a fuse holder near the battery that protects the main power wire (you'll have to install this fuse holder). some amps don't come with onboard fuses — you have to find their fuse ratings in their owner's manuals. for longer), and a fuse near the battery (140 amps or whatever the wire manufacturer rates their wire). your system's chain of components is only as strong as its weakest link, so don't cheat your amps and speakers with substandard power cable and speaker wire. wire can burn and melt if too much current is running through it so one wire is your best bet.-setting the gain (those last two steps) is important, to compensate for whatever eq or boosts were applied, so your amp's gain will be set for exactly how you listen to your music." in this article, just above the comment section, for help doing that. every time you halve the speakers' impedance — switching from a 4-ohm to a 2-ohm sub, for instance — you effectively ask the amplifier to double its output. just installed a pair of pioneer 12" subs and a mono 2000 watt amp. if you're designing a subwoofer system, ask yourself the following questions:How many subs do i want? are also known as "door speakers", "vocal speakers", "6 by 5" or "6 by 9" and more. if you’ve already installed a power wire for an existing amplifier you may choose to simply install another wire for additional amplifiers. the amp, 550 rms, that i am using or the sub? this prevents your head unit from trying to deliver too much current which can burn out the turn on circuitry in the head unit.

people with many components and wires running through their car can easily end up getting "ground noise," which is the whining sound that plays through your speakers and rises and falls with the rev of your engine. you'll be able to push your subwoofers with the mono amp's maximum power, without running at a dangerous impedance. do you think my best setup options are moving forward? you can connect the left front and rear speakers to one channel, and the right front and rear speakers to a second channel, and bridge the other two channels to run a subwoofer. amps that work with loads as low as 2 ohms per channel usually can safely drive loads only as low as 4 ohms when bridged. why don't you give us a call and one of our advisors can help you figure out which factory amplifier by-pass harness can be used in your vehicle to install an aftermarket amplifier. you should never replace an amplifier's fuse with anything except the size fuse the amp came with. meaning would i be able to get 4 channels on 4ohms and the sub on 2? a amps always have current flowing through their output transistors (or tubes). if your subs are single voice coil and each can handle roughly 2,500 watts rms, then that amp should work nicely if wired correctly. and your sub should be safe being run by that amp as long as you don't play distorted signals in attempts to get louder bass.'m looking to have 2 15' subwoofers hooked up in my room and i would like the amp to run off of wall power. capacitors are usually small cylinders that come with a digital display showing your voltage in your car. sub-bass frequencies would be sent to the subwoofer amplifier and high pass signals would be passed to the other amplifiers. two amps until i sold one of them now i'm only using one amp. mtx subwoofer has two sets of speaker connections, which means it has two voice coils., the power supply you would need is expensive and rare.: no, you cannot bridge a mono amp because there is nothing to "bridge. in that situation, you'll need a relay on the turn-on lead that gets triggered by the receiver but gets the 12-voly turn-on signal from somewhere else, like the fuse box.: no, you cannot bridge a mono amp because there is nothing to "bridge. currently have a jl slash 500/1 and a jl jx 500/1d mono amps. the crossover, along with the increased output from the mono channel, makes this an ideal way to power your sub. normally, when you want to add a subwoofer to a factory system, you use a line output converter (loc) connected to the factory speaker wiring. a capacitor can help if your system is drawing a little too much power. & videos: home  /  car audio, video & gps  /  car subwoofers & boxes  /  subwoofers faq. if you can't find a convenient ground screw or bolt, drill a hole for one. but when you're looking for really big bass, you'll need at least a 10" or 12" subwoofer and a minimum of 150 to 200 watts to drive it. an amplifier needs some open air space around it to dissipate the heat that builds up as it works, otherwise it will overheat and shut down. installing a fuse of the proper amperage on your power cable protects your car and gear from the dangers of a short circuit. best way to connect multiple amps when it comes to rem, is through one remote wire.: what size power and ground wires do i need for my amplifier?: what are the benefits of hooking up two subwoofers to a mono amplifier? have 2 speakers in the front doors, two 4 inch speakers i put in the dash tweeter spots, 2 speakers in the rear doors and a sub in the back of my suv., you'll want to make sure your powered sub has speaker-level inputs and "signal sensing" turn-on capability. mono, 1-channel amplifiers are designed to work with a wider range of impedances, and have tone controls and filters specifically made to help reproduce bass through a subwoofer., every 5-channel amplifier that i've encountered can handle driving 4-ohm speakers along with a 2-ohm sub. i will tell you that if you have two svc (single voice coil) 4-ohm subs rated for 200 watts rms each, you'd look for an amplifier that can put out between 300 and 600 watts rms at 2 ohms, like a kenwood kac-5001ps.: my amplifier is hooked up, but it won't turn on., it sounds like you've got two pairs of subs and speakers wired together in parallel and also to the outputs of your receiver and sub amp all at the same time., this will be the best resource for you as you decide how to wire your subs.'s a good rule-of-thumb guide to sub power:If you're using your car's factory stereo — 50 to 200 watts rms of power for the bass will do nicely. is an article about how to install a multiple-component, high-end car audio/sound system. not knowing what gear you have nor how it was wired together makes it impossible to say what caused the change in volume. you want to bridge a 2-channel amp to one channel, it's best to only connect one 4-ohm woofer. amps that work with loads as low as 2 ohms per channel usually can safely drive loads only as low as 4 ohms when bridged. do i remove the front dash and door side panels? this is an important difference when using your amp to power multiple subwoofers, because you won't be able to bridge your multichannel, 4-ohm stable amp to power multiple subs that present less than a 4-ohm load. most factory receivers can put out about 10 watts per channel, so a sub amp of from 50 to 100 watts rms will keep up nicely.

Wiring Two Amps in One Car Audio System

the turn-on lead must be connected properly in order for your amp to power up., are you asking about an amplifier's 12-volt remote turn-on connection or a subwoofer amp's remote level control? have a jensen 4 channel amp (duba4100), a kenwood head unit (kdc hd262u), rockford -fosgate 5" (r142) in the doors, and rockford-fosgate 6x9 (r1692) behind the seats.: we carry a large selection of subwoofers that fit in pickups., the way subwoofers are wired together and to amplifiers greatly affects their output power. since the average music signal requires about 1/3rd of the average power in a test tone, divide by 3 (87 amps divided by 3 = 29 amps). where the port aims in your car, however, can make a big difference. once you've found the right amplifier, look for subwoofers that complement your amp in terms of power rating and impedance. you need to install a fuse at the battery to protect the power wiring, your car, and yourself against fire, in the event of a short circuit. usually recommend that you drive your speakers/subwoofers with at least 75% of their total maximum rms (not peak) rating to get them to perform at their optimum. is it possible to run the sub off just one channel? not knowing exactly which subwoofers you have make it impossible to give accurate advice on which amp to use. mono amps have two sets of speaker terminals for convenience of installation: if you are hooking up two subs to the amp and using large-gauge wire, it gives you a place to attach the wires without having to trim them, appearing as if each subwoofer gets its own terminal. peak wattage, often double the rms value, is a description used by the marketing department of the amp's manufacturer to sell more amps. the closer to 100% you power them, the harder they hit and the better they sound. class d amps can be very small for their power ratings, and that's why they're showing up more and more in the mobile audio world where space is at a premium. my question has to do with supply power cable size and grounding location. the amp did not turn on, you most likely have a damaged amp and need to replace it or contact your dealer to arrange for its repair. personally, i prefer to run one new wire that is large enough for all of the amplifiers and any planned upgrades. how can i power all of these wit one 5 channel amp? happens when you hook up a single15in dvc 2ohm wired to 1ohm load and 2 12in dvc 2ohm wired to 2ohm load to the same mono block 1ohm stable amplifier? if you want a question answered about your system, you must identify the equipment by brand names and model numbers, and, in your case, how they're connected., use electrical tape (your best friend when dealing with wire) to cover up exposed wire. subs need substantial amounts of power to reproduce bass, so it's absolutely essential to use an outboard amplifier with them.: your ground wire should be of the same gauge as your power wire and must make direct contact with the metallic body of the car. some familiar music and turn up the receiver's volume until you hear the music start to distort, then turn it down a little so it plays clean. 100 watts rms or higher per channel system — you'll want at least 1,000 watts rms for your sub. you just have to find it for a good price and have it installed. do you have any insught or advice on where to put everything? crossover point between 60 and 80 hz focuses the power of your subwoofer amplifier on your music's deepest notes (the ones you feel) and helps make the bass you hear seem like it's coming from the front of the vehicle along with the rest of the stereo image. star washer will help your ground wire maintain solid contact with the car body.: how can i drive a pair of speakers and a subwoofer with a single car audio amplifier? your thickest or lowest gauge wire should be your main one. can i bridge my amp and run two in parallel? if you only have one channel, there's nothing to combine it with. your enclosure with the right amount of polyester fiber can make your box behave like it's larger than it really is. keeping that in mind, our two favorite locations are under a seat or in the trunk. with either, you’ll need to tap into your car’s speaker wires to get to the high-level signal the stereo puts out. lower number is the absolute bare minimum amount of wattage you need to get acceptable results. this makes it so that if one amp suffers a catastrophic short circuit, for instance, the damage will not spread to the other amps or your main power cable. if you're into imaginative looks and style, square and triangular subwoofers might be for you. one point for every dollar you spend and use those points to save on future purchases.: one way is to get a 3-channel amplifier, with two channels for your front speakers and a dedicated single channel with more power for your sub. you have a really powerful amp that's 3000w rms or higher, then you can really power multiple subs at once without any problem., jbl and jl audio both make quality amplifiers, so for bass i doubt you would be able to hear any differences. otherwise, if one amp fails, you may find yourself overwhelmed and needlessly tearing out wires. turn up the receiver's volume until you hear the music start to distort, then turn it down a little so it plays clean. then you'd connect, via rca cables, the loc to the sub amp's inputs.

the dvc sub can be wired in three different configurations: parallel, series, or independent. the key thing to know about impedance, then, is how to match your speakers to the capabilities of your amp. also connected two a second battery with 0/gauge wire to amp. a key to getting the most out of your audio investment is choosing gear that will go to work for you now, and won't become obsolete as your system grows.: impedance is the electrical resistance of a speaker or sub's voice coil to the voltage put out by an amplifier. mono here refers to a single channel (as opposed to stereo, or two channels), not one speaker.. so i hooked up my new subs, and they are awesome, although i know they must be grossly underpowered. use our vehicle selector to find out if there’s one that’ll fit yours. if you want to power your 100 watts rms rated speakers at their highest level just short of blowing, get a 4-channel amp that can put out 150 watts rms per channel at 4 ohms, like an alpine pdx-f6. i don't know what buck was thinking but he answered the question incorrectly. while two 12"s may give you more of what you want on paper, it's worth assessing the power you're using with your current subs. then, you'll tap into the speaker wires behind your stereo, or possibly the rear deck speakers. if you haven't purchased the amp yet, remember that you're looking for rms rating and give the "subwoofer wiring diagrams" article another look to help guide you. if your system was put in by an installer, i suggest you take your car back to them to make it right. keep playing the familiar song over and over again, as you continue tuning your system.: a dual voice coil subwoofer has two separate voice coils (each with its own connections), offering more flexibility in system wiring than a standard sub. your amplifiers in reverse fashion — one 10-gauge and two 8-gauge ground cables run from the three amplifiers to a 3-way grounding block.: your car's alternator ampere rating determines how powerful an amplifier you can install. your factory radio won't have rca outputs to connect to your amp's inputs, so you'll get the signals from your vehicle's factory speaker wires., it's usually cheaper than two wires in terms of material and labor costs. the receiver, adjust the eq presets or tone controls to how you like your music to sound. your system grows, you may dedicate a separate amplifier to your sub., a bandpass box is probably the best enclosure to fit your needs, but it's worth playing with placement before you change anything. i want to run both of them to power 2 jl w6 subwoofers.: subwoofer cones, like speaker cones, are made of treated paper, synthetics (like highly oriented polyolefine) or composites (like aluminum or injection-molded quartz). multiply the ampere rating by 40%, and you'll get a rough idea of how much reserve current capacity your car's system has.: if i put my subwoofer box in the trunk, will i be able to hear the bass? "bass heads" may have 3 alternators, 5 batteries, and 5 caps all in one car just to keep it properly powered (and a professional car charger just it case it still dies). typical car stereo amplifier is stable down to 4 ohms in mono (or bridged) mode or 2 ohms in stereo. but if you like the sound coming from the rear, go ahead and amp the rear speakers instead. experts help you pick the ideal gear for your needs. since the remote wire basically tells the amp when the radio is on, all amps can be connected to the same remote wire. i want to get a 5000w max mono amp for them, but the problem is that my subs are 2 ohms each and the amp is 1 ohm stable, and only puts out 5000w when it's 1 ohm stable.'s say that you want to install a 200-watt mono subwoofer amp, a 75w x 4 amp for your door and rear deck speakers, and a 30w x 2 amp for your dash speakers — 560 watts of total system power. another example might be using a 4-channel amp to drive your left and right speakers with two of its channels, while driving a sub with its other two channels bridged together, saving you the need to buy a separate sub amp. however, many complications can arise from using one wire to power many amps.: because mono amps tend to be class d amplifiers, they are a good choice for powering subwoofers — class d amplifiers have a high power-to-heat ratio and excellent efficiency, which are exactly what you want when dealing with power-hungry low frequency signals..I've heard about using pc power supply but i dont know how much heavy supply i need. you'd lose the stereo's front-to-rear fade function, but you may not care about that. and when the weather gets warm, even more people tell us they're looking for a system that can deliver roll-down-the-windows volume. seems to be some confusion when it comes to installing more than one amplifier. i can't tell if those subs are dvc or svc models.. it's more difficult for your ears to determine where low frequencies come from than highs), bass is often transmitted in mono. for pickups — what do you have that will fit behind or under the seat? on your amp, disengage all filters, set the bass boost to zero, and turn the gain down low. see our article about subwoofer enclosures for a full explanation. you definitely don't want this to happen, but if it does, a properly installed fuse will prevent a fire or other damage. next, you'll need to calculate the approximate current draw of the amplifier you're considering installing.

how to hook up two amplifiers 1 for sub & one for mids & highs

i did find that amp's power specs - 200 watts rms at 4 ohms, 400 at 2 ohms, and 600 at one ohm - but i'm not at all confident that it will be able to actually produce that much power. dry cell batteries are a better choice if you can afford them.» my amplifier is hooked up, but it won't turn on. for signal, you can run rcas to one amp and daisy-chain its preamp output to the other amp's input. audio signal travels from the back of your receiver to your amplifier through an rca patch cable.: an amplifier is considered a "high-current" amp if it can handle low impedance loads — less than 2 ohms per channel, less than 4 ohms when bridged — without overheating or shutting down.: subs for pickups — what do you have that will fit behind or under the seat?) people tend to underestimate the amount and size of wires that they need when installing many components in a car audio systems. the best way to power six speakers and a sub is with 7 channels of amplification. i install two powered subs (300 watts each) in my car? simplest, but ill-advised, method for connecting multiple amps is to connect the wire to the amp, and through the same terminal, have another wire extend out to the next amp. experiment carefully by applying it and listen to how it affects the tone of the bass and set it to where you like it. but if you upgrade to more powerful amps and subs, say 3000w, that 8 gauge will burn and melt in no time at all. or should the subs still be able to handle it? amps that can handle this additional heat build-up are considered 2-ohm stable. two 4-ohm speakers wired in parallel make a 2-ohm load., if you are running one amplifier that has 140 amps worth of fusing, you will need large enough power wire to support its current draw (4-ga. you wouldn't want your amp to be on all the time, draining your battery dead every time you park. you should always check the bridged minimum impedance specification before connecting a bridged amplifier to a low impedance sub or speaker system. you previously had a 1000w system, then that 8 gauge wire may work. and adding polyester fiber stuffing to any enclosure can clean up your bass by minimizing unwanted box resonances — and at a reasonable cost., my factory mids and highs were barely cutting it before, but with the new subs they're totally overpowered. you’ll also need to make fewer connections at the battery. the generally accepted way to connect a spdt (single pole, double throw) relay is illustrated below. in this case, you can safely go with either a 60 or 70 amp fuse.: when you wire a pair of speakers in parallel to an amplifier, you connect the positive (+) leads of both speakers to the amp's positive (+) terminal and the negative (-) leads of both speakers to the amp's negative (-) terminal. there i just bought two kenwood subwoofers 1600w max 800w each max 400rms total 200rms each 8 ohms total 4 ohms each and i am having trouble choosing a proper amp. fuse does its work by "blowing" and stopping the flow of current. you'll get twice the number of speakers and, usually, twice the amount of total power. getting a larger alternator that puts of more amperage, your battery will be continuously and quickly charged. a fuse is a lot easier and cheaper to replace than your car or your life. but you may not realize how polyester fiber stuffing can help your bass. my buddy matt and i experimented with his car and a single sub once, but it always depends on the vehicle and the subs. maybe you should check out a pro audio amplifier to run your subs. i do understand that scenario, just have issues trying to make these, dual, 2 ohm vc into to previous question. because your entire car chassis can be considered "negative" or ground, you can think of a short circuit as positive touching negative. i also recommend using the battery negative terminal as your grounding point - i think in the marine environment it's a more reliable connection than the engine block. you were to wire them in parallel it would put the max to the speakers. wattage is also a must if you want to hear those lowest bass notes. often this is done with a fused distribution block, so each amp gets its power line fused as it's split off from the main power cable. let me know if, someone, has figured out a way to break ohms law. used to be a way to utilize a 2-channel amp to drive two speakers and a sub that was called the "tri-way mode. connect the next battery by running a wire from the first battery power, to the second battery power, and so on until you reach the last battery. if you can't do that with an amp mounted under a seat, choose another location for it. one power wire (wire that connects from the battery to the amps) to your distribution block." bridging means combining two amp channels together into one, in order to get more power.'s polyester fiber stuffing, and how will it affect my subwoofer's sound? remote is bad on the amp connection what can i do.

6 Ways to Install a Multiple Component Car Audio System - wikiHow

what sub could i get to add to the system. that gets all your speakers and sub going without needing to buy a sub amp, but you'll lose the ability to fade the music from front to rear. you have three amplifiers, two with fuse ratings of 20 amps each and one with a fuse rating of 25 amps. you get less power, but the amp runs cooler and is more stable. if you're asking about the differences in amplifier strength, then it all has to do with how loud people listen to their music, and how amplifier manufacturers respond to their customers' wants and needs. you go with a 4-channel amplifier, powering a pair of front speakers and a subwoofer is a breeze.: installare un impianto audio multi componente sulla tua auto, español: instalar un sistema de sonido multicomponente en tu auto, русский: установить многокомпонентную автомобильную аудиосистему, português: instalar um sistema de áudio automotivo com múltiplos componentes. if i hook up the subs to the amp, would it still put out 1 ohm load( to each sub), or is that 1 ohm gonna split equally between the subs, providing 2 ohm load to each one? thing to do is for power wire is connect each amp with a separate power using a distribution block, which is essentially a casing that allows one wire to supply power to multiple wires (one wire from the battery goes in and three wires can come out). a sub's rms power handling and impedance are essential to making a match with an amplifier. there are no formulas for determining how much power you gain when you bridge an amp's channels — every amp is different. can run more than one speaker from a single amp channel by wiring the speakers in series or in parallel. you should leave a few inches of air space around each side of the amp so that it stays as cool as possible.: amps usually put out more power to a 2-ohm load than to a 4-ohm load (most speakers). recently added two amps one for my subs and one for my front door 2 way 6x9 speakers. would you say this is a good idea and can it harm my subs? you can optimize the protection your fuse provides by installing it as close to the battery as possible — that increases the length of the protected cable behind it. this amp doesn't show a rating for 4ohms just 1&2ohm. don't mount an amp upside down — the amp will not be able to dissipate heat effectively, and overheating can damage or destroy your amp. speakers or subwoofer voice coils are wired in series — one after the other, a plus of one to a minus of another — you add their impedances to get the total impedance. if you are using more than two subs, then you simply use parallel or series wiring (or a combination) to get as close to the minimum impedance of the amp as possible (see our subwoofer wiring diagrams for more information). if you don't hear any distortion, even at full volume, set the receiver's volume to ¾ full. this question (or a similar one) is answered twice in this section, please click here to let us know. make sure that the sub's peak power is rated above 1000w." this method used a special "tri-way" crossover connected to the two channels of the amp that created a third, subwoofer channel. how many watts would each sub receive in this setup? now i have the sub wired in parallel to 1 ohm. if your 2-channel amp is tri-way capable, a tri-way crossover setup may be just the affordable solution for your system's upgrade. in multi-amp systems it is often necessary to use the turn-on signal from the receiver to power a relay, which in turn supplies the turn-on signal to the amps from another power source. without one, an accidental short circuit could pose a fire hazard and damage your amp (not to mention your car). the upside of class a operation is its linearity — class a amps produce the cleanest output with the best fidelity and least distortion of any other class of amplifier. there are no formulas for determining how much power you gain when you bridge an amp's channels — every amp is different. you can use this article to confirm if this number is correct for your system and this article to help you with wiring. the best way would be if your head unit (radio/deck) has a separate set of outputs that can be used on the extra amplifiers. if you drive a quiet car with the windows up, you'll need much less power than someone who offroads in a wrangler., first of all, under no circumstances should you ever mount an amplifier under a carpet. you'll simply want to run your amp in what we call 3-channel mode. addition to running power, ground, and a remote turn-on lead, your amp hook-up requires input signals. but most importantly, make sure you have the correct wires for the job. so unless the amp's specs and literature say otherwise, you will be alright hooking it up that way. just be sure to keep the gain low or you could blow the sub. an 8" bazooka at 200 watts outperform a 10" sub in a sealed box? the relay will then connect the 12 volt signal to the amplifiers and other components.'m running an jx1000/1d amp (1000 watt rms) with two 12" polk audio db1222 subwoofers rated (720 watts rms). in the case of a factory system with no remote connection, you can tie into a switched 12-volt source, one that only comes on with the car, in the fuse box.: a disadvantage in bridging amplifiers is that you must be careful not to hook up too low of an impedance load, or you could damage the amp. at that time, you could add another pair of stereo speakers for rear fill, and run your 4-channel amp in 4-channel mode., without more specs, we don't have an answer for you.

How does carbon dating work yahoo answers

if you installed it yourself, you'll need to proceed carefully when implementing a fix - plugging and unplugging cables could produce a spark which could fry delicate electronics. it’s always better to have a power wire that is larger than you need than a power wire that is too small. then, a 4-gauge ground cable connects the grounding block to your vehicle's chassis. you should always check the bridged minimum impedance specification before connecting a bridged amplifier to a low impedance sub or speaker system. a thin strip can stop your entire system from being nothing but overpriced junk. it runs from the remote turn-on lead at the back of your receiver to the remote terminal on the amp. note: for your personal safety, and that of your equipment, always remember to remove the power fuse before disconnecting or reconnecting your amplifier. i have a escalade and have 2 10" sub's in a bandpassbox behind third row but its quiet outside truck but everyone else i know has bass u can feel . then you'd run speaker wires from the amp's outputs to your subwoofers. however, you need to properly set your amplifiers' gains, not at their minimums. 2 2 ohm speakers in parrelel wiilll gift you 1 ohm load at amp. with a subwoofer with a high efficiency (sensitivity) rating housed in a ported or bandpass box.» what's the biggest amp i can hook up to my car's electrical system? if your sub amp has speaker-level inputs, you won't need an loc, you'd run speaker wires directly to the amp's inputs.» how much power do i need to get optimum performance from my car's sound system? if you plan on a high-powered system using, say, a 100 watts per channel amp, however, then you'll want to run new and thicker speaker wires directly to each speaker from your amp's output. they're designed to work with a wide range of impedances, and have tone controls and filters specifically made to help reproduce bass. back the volume knob down a bit, and your woofer is safe; clean, high-volume sound will not damage your speaker., have you tried taming the brightness and distortion by adjusting your receiver's tone controls and the amplifier's filters and boost?: if you're looking for the sub that will deliver maximum spl (play loudest), you need to consider sensitivity, enclosure type, and available power. you have a feeling that you may go bigger in the future, chose bigger wire. if you are using more than two subs, then you simply use parallel or series wiring (or a combination) to get as close to the minimum impedance of the amp as possible (see our subwoofer wiring diagrams for more information).) then you can use an electronic crossover to split and filter the signal going to each amplifier. one point for every dollar you spend and use those points to save on future purchases. to do this, bridge the rear channels to power your subwoofer, while the front channels drive the pair of regular stereo speakers. can also "stuff it" if you simply don't have room in your vehicle for the larger box your sub demands. by figuring in a typical amp's efficiency and the normal voltage of a running car, you'll find out the maximum current the amp will draw from the electrical system and exactly which size wire you'll need so it will all work properly. be certain your amp is 2-ohm stable before wiring speakers in parallel.: the thin blue wire is called the turn-on lead, as it carries a signal that turns on your amplifier., i can't recommend a setup for gear i'm unfamiliar with which crutchfield doesn't carry., you should first check the wiring and correct any shorts or loose connections.) and mobile security (car alarms and remote start) to subwoofer box design and fiberglass fabrication. but if your alternator is really 70-amps, then about 35-amps would be available for aftermarket equipment, which would support a 500-watt amplifier at best. if you're trying to install more than what your car originally came with, the same rules should be applied to those of subs. what is an adequate amp that will provide enough power for both of these subwoofers without overpowering or underpowering them? can you wire a sub box with two terminals while making all power go to only one sub? b: bridge the rear amp channels together to drive the sub. the drawback is that the signal voltage is also split so that each component is now getting a smaller low level signal which may increase the noise in the system. methods:connecting multiple ampsmultiple sub woofersmultiple mids and highsmultiple wiresmultiple batteries and capacitorsfinishing touchescommunity q&a.: to experience the lowest possible bass tones, select a large woofer designed for use in a sealed box. you parallel wire two 4-ohm speakers, the amp sees a 2-ohm load. this is an extremely inefficient method of raising power and class a amps are large, heavy, and run very hot. if i remember it will power up when needed for the conversation and then powers back down. would their be much difference between sticking with jbl, or going with jl amps? also need another length of the same gauge cable to serve as your ground wire., compare the amplifier's approximate current draw to your vehicle's reserve current capacity to determine if the electrical system can support the amplifier. for example, a 2-channel amp that puts out 75 watts rms per channel at 4 ohms may be able to put out as much as 200 watts rms at 4 ohms into one channel when bridged, which could be great for running a subwoofer. i took my system out of one vehicle and installed it to an other, no big deal my amp for my 6*9s and speakers work but cut out if i turn up to loud.
