How do you hook up subs to a factory radioin your rca plugs and check that the signal is being taken to your amp or sub, wherever the other end of the rca wires are. keys to remove your head unit, you may not need these depending on the manufacturer and fitting type in your carmultimeter. this loc connects to the factory speaker wires and has rca outputs for your amp.?I had the same question about installing a sub to factory radio, my wife has an 05 altima with a factory bose 6 speaker system that i really don't won't tear into, and it sounds pretty good, i would just like to alitte low end maybe a 8'' or maybe a 10'', not looking for a ground pounder , there is what looks to be a small amp mounted under the back deck lid, could i just tie in to the wiring harness there? i don't want to redo the whole thing, but would like to add a sub ( and amp? good luck with your install, it took me a couple of hours, but you won't have to keep stopping to take photos ;)hmm. it works, check the remote wire output from your converter by using a voltage test between the wire and a ground, you should get a + reading from 5v to 12v depending on your converter. you believe your intellectual property has been infringed and would like to file a complaint, please see our copyright/ip policy. up your scotch blocks to stop them rattling around and to keep the cables bundled up neatly. if your local dealer is nice they may give you a hand, though be sure to look on the internet first as they'll probably want money. you tap the input side of the amp you dont even need a line out converter you can just splice some rca plugs in and get your signal there.. can i still add the sub to the stock radio? if you're using after market stereo there will be a blue wire coming from the wire harness in the back, mostly these are attached so you have to splice, just snip them and tape off the old end and run your remote wire to your amp. is very important when matching subs and amps, yes not enough power will make subs clip, but also to much power will burn your voice coils by over heating them with too much power .. you should be able to connect it to the auxiliary on the back of the stereo unit. can i hook a sub up to that or do i need to get an aftermarket radio? a good 1000 w set of speakers if you are going to pump out sound at least don't try to put 1000w into a 500w speaker, your will toasty that baby every time you crank it up. you need to do is get a rca wire, cut in half, strip both the outer and inner wire. would cause my sub to kick in when radio is on and stop working when i change source to cd?
seems you know your stuff maybe you can help me out with this problem? you believe your intellectual property has been infringed and would like to file a complaint, please see our copyright/ip policy. amp with at least 1000w on 2-5 channels with a bridgeable setup is pretty cool just be sure to buy at least a 1 farad capacitor to run the thing, you really do not want a fail in power and do not want to run an extra dry cell battery and a new secondary alternator. if you dont have the code and you unplug your stereo it will not allow you to listen to it as it will assume it's been stolen.
thanks in advance if you can help
frankvery cool, but one contemplation here. get your capacitor as close to the amp as possible, and use the same ground as you did for the amp. as i say its not really influencing the signal to the rear speakers, i doubt it makes any difference you could detect with your ears even at high volume. if you have a 2 ohm sub and a 4 ohm amp it won't produce enough power to properly power the sub. you cannot just plug it in; you must charge it first with a resistor, use a 1k ohm resistor because they do not get as hot, it only takes a few seconds to charge, do not do this bare handed. gmousersuitcase boom-boxby garren11basics of car audio (speakers and subwoofers)by dragonz2444back wooferby dustintranslatestoawesomefeatured channelswoodworkingpaperkitchen hackspuzzleslaser cuttingspacehomesteading3d printingsewingnewsletterlet your inbox help you discover our best projects, classes, and contests. converter i bought also gives you a "remote wire" output which tells your amp when the car is on so it doesn't drain your battery, if you get a converter without this option you can just join the remote wire to the acc circuit of your car, or the 12v circuit with a switch (you will have to remember to turn it off though or your amp will drain your battery).
i have installed a kit like you are talking about, it was 4 or 5 speaker wires that were spliced total.
Factory Radio Improvement through OEM Integration & Upgrades atyou tap the input side of the amp you dont even need a line out converter you can just splice some rca plugs in and get your signal there. want to know how to hook up subs and amp to stock.
have you encountered any issues with your system after doing this? have your power wire taunt and find out where your cap. try turning the amp down and your stereo up i've had no issues at all, the converter doesn't put a load worth considering on the rear speaker circuits as it's only really listening to the signal, it draws all its power separately from a 12v feed. A "Low line converter" is a device which will piggy back your speaker outputs from your head unit and convert them to Low Line RCA outputs for your amplifier . all you need is a line converter that will hook into your rear speaker wires and into the amp. you would like to learn more about one of these? once you have it go unscrew your stock stereo, unplug it, plug in your new wiring harness, and plug in the other end to your stereo. if you wish to keep the factory hu, you can also install an aux adaptor which will give you rca input. the amp will have a built in crossover to get rid of the unneeded high and mid frequencies and leave you with a good sub signal to push thru to your box. you'll need:low line converter, i got mine on ebay here for £6. if you dont have it then you should acquire it from your car manufacturers customer service phone number, your local dealer or the internet. this happens when i switch the car off or when i open the door. converter should come with wiring instructions so you will just need to match up the wires and splice them with the scotch blocks, use the pliers to press the metal splice bar so you can be sure of a good connection. the amp where you want it, then attach the ground (black or brown) wire to the amp. if you're using your stock head unit you have to purchase a toggle switch that fits your fancy, find a cool place to mount or hide it, from here you want to attach the remote wire to your amp, run it to your toggle, cut it, attach it to one terminal, then attach the end you just cut to another one. where you are going to mount it and work out if you need to add any wire to your converter to get it to reach comfortably to where your head unit cables are. you may need to twist and install both power and remote together or you can install it in the slot marked remote.
can i hook a sub up to that or do i need to get an aftermarket radio? take into account that your head unit will need space behind it to fit back into the dash properly so don't count on splicing into the cables right at the plug with the converter right behind the head unit, it may be better to mount it somewhere else and lengthen the wire to reach. (besides, the stock radio didn't have as many options as yours. i have a 2012 ford focus i just want to know if i can hook up subs with the stock radio?. if the line out converter is not connected to the stock deck/dash unit, then there won't be a music input for the subs to function.
i have a low-level converter here (not that exact brand you're using, but surely they must all behave the same way) that i'm going to be installing in my car, but i didn't want to lose the 4 in-car speakers (regardless of how weak and pathetic they are) in the process. make sure you always turn off your amp when you leave your car, it will overheat and drain your battery. you tap the input side of the amp you dont even need a line out converter you can just splice some rca plugs in and get your signal there. does it mean for me to attach the cables together by the wires, and then plug it in? you want to take out a door speaker and run 2 of the 4 speaker wires to it, pay attention to the positive (+) and negative (-) terminals. to hook up subs and amp to stock stereo in car? then unplug everything, put it all back in your dash and plug it all back together again. with the converter you get a small box with 2 rca's coming out and 4 speaker wires out the other. your rear speakers are on the rear deck, so its easy to tag on to your speaker wires there. you're using an after market head unit, go to an electronics store's stereo department and ask for a wiring harness from your car to the after market head unit. otherwise you can just undo the plug from the converter and then the back of the head unit. then hooked the speaker in the rear deck back into that. remember to shut off the amp if you do so manually. getting this wrong may well overheat cables or even blow the amp itself so make sure your cables and setup are matched.
head units rarely have rca or "low line" outputs which your amplifier will need for it's input signal. so if you don't have the remote wire from the after market head unit to turn on the amp when ever you turn on the stereo you have to turn your amp on manually. it doesn't work, make sure you have tested the connections with a multimeter and redo any that fail. when you buy the new wiring harness make sure its the same shape/size as your stereo. Want to know how to hook up subs and amp to stock. his head unit doesnt put out more power than his amp is capable of taking through the rca input. since i do not, by any means, plan to keep this sub longer than a monthish, all i did was splice the cable that is hooked up to one of the speakers in the rear deck and hook up the sub speaker wire. want to know how to hook up subs and amp to stock. your diagram with the below:The resistance between + and - speaker channels (on the same speaker) should get around 4 ohms. but i wanted a sub,I am planning on getting a new double din head unit in the next week or two. or so) would help with the spikes and not render the poor battery empty with every kick of the bass :dyou do realise that it's the battery that charges the capacitor, right? only comes on when the acc +12v circuit is activated with a click on the key turning in the ignition, at this point a blue light on the converter comes on, but that will be dependant on your converter and how you wired it, although i'm sure the converter draws a minuscule amount of power it's probably best not to have it "on" all the time, so be sure it is off when your car is.. previous comment disappeared :s take two:
thank you :)
i may not need to stop to take pictures of the process, but in addition to the rca outputs i also need to create and install a 12v-5v converter, a 7-port powered usb hub, headphone-radio transmitter, and other assorted goodies. for the rem wire, i recommend wiring it to a fuse in your fuse box to prevent battery drain. oh well, you can just pull the radio and tag the speakers there, you'll have to get an ignition source for the remote wire and its all behind the radio. like what connecters and stuff or if you can find a page online that has a guide on how to do it. have a pac sni-15 both rca jacks are black i dont know what the positive or negative is? if you have a stock stereo and you have the remote wire there you want to in twine the remote wire with the power wire before inserting in the power slot for amp. oh well, you can just pull the radio and tag the speakers there, you'll have to get an ignition source for the remote wire and its all behind the radio.
