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.
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.
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.
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.
