- How to Wire an Amp to a Sub and Head Unit: 12 Steps
Contact Account Shopping Cart. June edited March in Car Subwoofer Talk. Hi, I was wondering how difficult it is to add a sub to a factory car radio? In Home Audio subs can be hooked up with speaker-level connections; can this be done in the same manner with a car audio setup? And if so, would you have to run wires from the door speakers to the sub location, and then another set of wires back to the doors to the speakers?
Post edited by Serendipity on March June edited June You would be best to tie into the rear channel, this can be done the stock head unit. Good luck it will make a huge improvment. PM me if you need more help. How old is the car? Are you certain it doesn't have a sub or preout on the back?? July edited July 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?
Anybody have any idea which wires I would need to tie in to? Samsung 50'' 4k display Polk Signa-1 Surround bar. August edited August Most amps have high level inputs but most of the time I prefer to use a line out converter. Your rear speakers are on the rear deck, so its easy to tag on to your speaker wires there. These converters are around 25 bucks from your local car audio shop.
Music is like candy, you have to get rid of the rappers to enjoy it. 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. That's what is was. IMO, the Bose system isn't that great. That's why we went with the standard system. Bose never is -Cody. October edited October November edited November I replaced the stock speakers and tried to get them amped.
As soon as the speakers were amped up the sound shuts off. The place where i got the amp installed said that my oem unit cant be amped. Now i have nice speakers that i cant turn up loud. Is there any amp that will work with my stock head unit. Basically, you need more professional, more experienced shop to help you. The best way to do this would be to use a processor that corrects the audio coming out of the head unit before it gets fed into the amp. It already has 2 factory subs under the seats. Do I have to splice the LOC on both subs or just one? Whats the best LOC for such a job?
For this vehicle where would I get the best frequency results from?
Have you guys worked on such a vehicle before? My main concern is controlling the volume to a subwoofer. With many aftermarket headunits, they have sub volume control so you can lower the subs volume and turn up the other speakers or vice versa. What if any options are there for this if using a factory head unit? Hi Frank, Towards the end of the article I mentioned the option of a separate bass control knob. We normally take it apart and mount the box behind a panel so all you see is the knob itself. I am hooking up after market amp in range rover and have loc converter got to factory sub but has four wires red and black also green and grey on the other side which ones do I hook up to to get bass for after market subs.
If we have a factory sub we typically tie the positives together and tap into the single positive lead of the sub and negatives together and tap into the single negative lead of the sub. I had my installation done by so-called professionals. They are powered by: Here is the problem when I play music too load the system shuts down. The shop that did the installation put a converter and they say that everything is fine. They say the problem is with the factory radio. Could this really be the case. Hi Allan, sorry to hear about your experience, but it sounds like a bunch of unprofessional installers.
Did you have the stock JBL amplifier in that car? Or just the basic head unit?

Typically the only things that will cause an amp to shut down like that is a bad ground or a signal that is clipping causing the amp to overheat and shut down. By the way, it would sound way better with an aftermarket head unit, just an FYI. When I play the radio the sound is low, lacks bass, cannot enjoy it at all. Radio volume cabln be cranked to the maximum.
The bass is overpowering. The highs are sharp intolerable. Previously had the same amp and sub with zero distortion.

Is it possible that this car cannot be fitted with and amp and sub? The stock set up was better than it is now. Most Honda Accords are equipped with a noise cancellation microphone in the cabin — it needs to be disconnected, that will fix your problem! When the install is complete and I hook back up the battery neg terminal to the car, the system works and sounds good.
But when I shut my car off and then turn it back on my amp comes up with the red light protection error every time after. I have no idea why. The factory system is the beats audio. Do I need to keep the factory sub installed and wired up too? If it does, that would indicate possibly a poor ground for the amplifier. Hi Annie, I have an 06 maxima with the factory premium bose sound system. All i will need is a LOC with bass control, to tap into the rear stock sub and wire the amp kit like normal right?
Also, the watt amp has watts rms x 1 channel 4 ohms bridged , and my sub is 4 ohms, watts rms watts max. Is this amp good enough to get nice bass from the sub? Or do i need to upgrade to a bigger one before i hook it up? I want bass without having to buy a new alternator lol…. Hi Ashton, yeah you got it right. Can you do that or am I way off the mark? Hey Ben, it really kind of depends on your equipment.
If not, yeah I would grab a 4 channel line output converter and use two separate RCA cables — one run the front channel and another to the sub channel. Additionally I would get a bass knob so you can have an independent sub level volume control as opposed to adjusting the bass on the head unit which will adjust bass levels to all speakers. I just installed a aftermarket radio in my 06 Chevy Equinox, everything turns on and looks like it is working but no sound is coming out.
Any ideas as to what could be wrong? You probably have a stock amplifier that needs to be powered up.
Like if you have the Bose system? You would need to use the remote turn on lead from your aftermarket radio usually blue with a white stripe and wire that to the amp turn on lead in the car harness. Hello annie,awesome blog here! I am very familiar with audio systems and have performed all installs on my personal vehicles. I recently was stumped with my lastest install in a ram pick up truck. My question is if my oem amp is filtering out my signal to my 4 channel amp is it then best to tap the wires previous to the oem amp to achieve a better sound?.
Whats happening is my door speakers are either entirely flat with no tweat,or they are all tweat. FYI its a ram with a line out converter and aftermarkyamp already in place. You may need to do an audio processor that sums the frequencies off the stock amp prior to your aftermarket amplifier so you can get a true full range signal.
Here are my questions. I have a F with Sony premium sound system. I can see the stock amp and stock sub. I have read that the amp also powers the door speakers. If so, what LOC would you recommend? I have a bass knob already that connects to the kicker amp that I want to install. I want to keep the look of my truck stock so I may swap out the stock door speakers, tweeters, and center speaker.
If I do so do you think the stock amp will do the aftermarket speakers justice? I was thinking of replacing them with Polk Audio components in the front and coaxial for the back. Hi Rob, Thanks for the comment, I appreciate it! Ah Ford and their lovely Sony system. And they have so many variations! I can understand wanting to keep the look stock. I recently did this in a Subaru with Morel Tempo speakers just did speakers and dynamat off basic stock stereo and was pleasantly surprised at the justice the stock stereo did for those speakers. And if you ever did want to change the stereo, keep a look out for Alpine and iDatalink.
So in the future there may be some nice options. Does tieing an LOC in parallel to the speaker circuit effect the circuit impedance? I think maybe you just mean running along side with rear speakers operating. So you can and are supposed to have your LOC installed along side your rear speakers. I hope that makes sense! Next how do i connect the wires in any case?? Do i have to keep the harness plugged into the head unit or do i have to keep it unplugged as i read somewhere you cannot power the speakers from both factory hu and amp simultaneously..
And while feeding the amp output back to speakers n subs we connect speaker wires to each speaker leads, so whats the difference between amp input signal n amp output signal, its confusing me as for eg. You can take the speaker leads off the back of the stock stereo and route them directly to your amp.
The LOC is your input signal. That is feeding the actual audio signal to the amp. The amplifier amplifies that audio signal and feeds it the speaker output. What if I were to tap into the factory speaker wires without the converter by cutting and splicing a rca cord? I think he only does this in cars that have a stock amp and have a direct low noise pre-amp level audio signal. I have an 07 maxima with a Bose amplifier. Should I tap into wires that input into the bose amp or the output wires and which colors. Hey Chris, sorry for the late reply, was busy trying to survive the holiday season at our shop.
OnDemand lists black as negative and white as positive on the stock subs. Other wise, probably behind the radio. Sounds great only one problem when car goes on or off i get an annoying distortion sound on subwoofer. Try switching the source for your remote turn on lead to a different accessory power source. What would work best? When in doubt, I would go straight to the stock sub. Where is the best place to hook up a line output converter when adding an amp for a sub?
I may have missed it somewhere. Hey Keith, you can grab that signal right at the stock Bose subwoofer. Like a positive one side of sub and negative on other side of factory sub? The stock amp really is not powerful enough nor designed to run the impedance of your MTX. So definitely get the LOC and a separate amp to power your MTX — you could also get an amp that has the LOC built into it too, but either way definitely just grab your signal from the stock sub, but use that signal to feed a dedicated amp to power your MTX.
I have a ram with premium alpine system. I want to add amps and a sub. The car is canbus equipped. How do I get a clean signal for amps. Anything I add must be tied in post factory amp. I need to clean the heavily processed signals. I will tune via aftermarket amps.
Adding subwoofer to stock car radio?
Not interested in complicated dsp…. Hi Fred, I feel your pain. You might want to would wait to see what JL comes up with, but it may be another 9 months or so before they release anything. They talked about this very problem at CES recently and they are in the process of designing a new product which tackles this exact issue.
You can read more about the new JL Audio processor here , scroll towards the bottom of the post. With this processor you also have the option of using a digital aux in so for a dedicated super high fidelity source, you can use an iPod running through a high quality digital to analog convertor straight into the processor. With Audison I had many defective units and it would take months, even over a year in one occasion, to have them repaired or exchanged one of the reasons we stopped carrying them. Sometimes you really only need to use two audio signals. So whichever route you decide to go, make sure you go to an experienced installer who knows what a frequency sweep is, a scope is, and what an RTA is and make sure he knows how to use them because you really need all three to set up a processor correctly in a vehicle like this.
Then when the Fix and the Twk comes out from JL you can clean it up even more. Those will be designed to do the tuning and tweaking themselves, making it a much simpler install. Hey I have a ram pickup with factory alpin system and touch screen deck. Has factory sub under back seat.. Had 4 wires going to that one sub.. Hi annie i have a question if i am connecting a line out converter on a factory rafio but there are no speakers installed the wires are there and i know which ones are going to each speaker how would i find out polarity on the wires. Hi there, I just bought a cadillac CTS and I wanted to know if its possible to hook up a sub and amp to the stock stereo,if I can how do I do it?
Of course you can!
I would add one clarification to your speaker polarity testing. Thanks for taking the time to post it! For readers that need more details on polarity testing you can check out this video post or this post on wiring up a head unit when the wires have been cut.

Hi i just bought a Lincoln mkz. I hooked up a line output converter and when i shut my car off the amp begins to work and apply bass. Im not sure why this is happening i read the directions,followed step by step. Everything works fine when i turn my radio on and off the amp goes off and on…. I got 2 10 inch kicker competition,and a watt power bass amp,stock radio….? Did you run the remote to an accessory or ignition wire in the vehicle so the amp goes on and off with the key?
Sounds like maybe you used the signal sensing feature of your line output convertor, they can do funky things like that. Try to find a true accessory or ignition wire to get the timing right. Hello, I just recently purchased a 04 Audi 2. I have a Infinity reference a mono-amp and 2x Infinity Reference w Inch that I used in my previous car and I have all the wiring as well looking to upgrade in the future but its what I have for now: Im thinking this will be a fairly easy task since I have everything except the LOC.
What im wondering is how would I wire the input to the LOC so that I can power both of my subwoofers. The Infinity subs would be wired to your amp just like any other setup.
How to Wire an Amp to a Sub and Head Unit: 12 Steps
Your only wiring options are running each subs voice coils series, then parallel the subs for a final 4 ohm load or wire the voice coils parallel, then parallel the subs for a final 1 ohm load. That amp is not rated as 1 ohm stable, which means you were probably running the amp at 4 ohms in your last set up. At 4 ohms it only puts out watts RMS. Your subs are rated at watts RMS each.
Do I need to pull the rear speaker wires from the deck and wire them into the LOC? There is also no remote wire in the harness, how does my am know when to turn on? You may want to get your signal from the speaker wires before or after the stock amp which is located underneath the rear deck in the trunk. I have installed an amp and speakers to my factory stereo, the problem I am having now is that every time I shut off my car and turn it back on there is no signal to the back speakers.
Hi Heather, I think I know what it might be, but to really answer this I would need to know a bit more. A line output convertor? Or did you cut and splice RCA cables into the stock speaker wire? Hi Brandyn, Probably running too low an impedance to the amp, this is the most common issue I see.
