Adding subwoofer to stock car radio?

Serendipity · June 2008

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?

Thanks!

You can P/Up a line out converter that converts speaker level to rca... or some amps have a high level input. 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??

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?

if 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

pm me ur email address and i can get u a diagram

2000 Nissan Maxima. I'm pretty sure it doesn't have any pre-outs; it's the stock system.

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.

Huh? There are no speakers on the rear deck, all of the speakers are in the doors.

Maybe you were referring to earlier Nissan Maxima's? I know for sure that the speakers were on the rear deck in the 1989 Maxima we had, but definitely not on the 2000.

Hmm...couldve sworn I just worked on an 01 the other day and the speakers were in the rear deck. 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 01 must've had the Bose system then. According to Crutchfield, if you don't have a Bose system, the rear speakers are in the doors.

exalted512 · August 2008

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:

I've got a 2000 Toyota minivan that I want to use the head unit (6 CD changer AM/FM [preamp onhly] by JBL) for the appearance of stock (so nobody jacks my system - live in a rental community w/high crime) but repace the stock amplifier with a 5 channel amp. I'm going to try to build a box that fits in the space in the rear where the tire jack equipment is now and put a 10 inch sub in there and mount some MOMO 6 1/2s in the factory mounts in the front doors and mid panels. Are there wiring harnesses out there that will allow me to do something like this with my factory head unit?

I have measured the space where the current amp is (center of the dash at the bottom, behind a storage compartment) and I may need to do a little trimming to make an aftermarket 5-channel fit. The sub would be a long way from the amp but I could fit a decent size box with a port in the location in the back. I will be running video (movies and PS2) at times and tunes at other times.

By the way, I saw your pics of your truck in the link in the "subwoofer to amp wattage thread". I wish I had the time to tear mine down and start from the bare metal like that. Pretty sweet and thanks for sharing.

Hopefully his head unit doesnt put out more power than his amp is capable of taking through the rca input...

Len, please forgive an ignorant newbie question, but is there a reason the rear channel is better than the front? I only ask because I just recently (this past weekend) installed a mono amp in my son's Dodge Dakota, used the "amp-supplied line out converter", but spliced into the front channel (it's a quad cab truck with four door speakers-all the same). It sounds great, but could it have been better if I had used the rear channels?
Thanks,

A lot of newer cars have a lot of EQ'ing in the factory head unit. Since they want to put together the cheapest stereo they can and charge a boat load of money for it, they use crappy speakers and EQ them to sound better. Generally the rear speakers have the least EQ on them as the higher frequency stuff doesnt matter when the speaker is 4' behind you and firing into the back glass.

Ditto what MacLeod said!

Option 1:
You pick up an "all in one" powered bass enclosure, since most will have level speaker inputs.
Many manufacturers offer these, below are a few that offer them:
Bazooka
Clarion
Infinty
JVC
Kenwood
MTX

Option 2:
You pick out an enclosure (custom, vehicle specific or universal) that fits your vehicle, add the recommended subs and use an appropiately sized amp that has speaker level inputs.

Regardless of whether you choose to go with a self powered line level subwoofer or with a custom enclosure powered by an external amplifier (w/line level inputs) you can still use your stock (OEM) radio.

ive got a 98 subaru legacy wagon. i wired the amp to the battery grounded it, wired the remote on to a 12v source in the fuse box. and got a audiopipe rca converter and hooked it up to the rear speaker wires behind the head unit and ran the cable to the amp.. the amp is on. and getting power but no sound is coming from the sub:mad:.. idk what to do now.. i checked over everything

bigmike441 · February 2010

All you need to do is get a rca wire, cut in half, strip both the outer and inner wire. then take a piece of speaker wire, strip and slit about 2 inches. take the outer cover off your back speakers and connect the two ends of the speaker wire to the stock speakers, one end to possitive and one to negative. then attach the other ends of the speaker wire to each end of the stripped rca's. repeat to the other side and now you have to rca wires to plug into your amp.

Yes, what he said. I tied into the rear channel of my old ranger and that worked perfectly.

i have a 96' Volkswagen Passat with a stock deck, hoping to install two subwoofers and an amp. Will i need to buy a new deck, http://www.bestbuy.ca/en-CA/product/sony-mp3-wma-cd-car-deck-with-aux-input-cdxgt240/10130574.aspx?path=dcd23133cc0cf54c33aa2873ae6869a6en02, or can i just use my stock radio deck?

MTS · July 2011

Hi guys, I just got a sub 6" or 8" with a maximum of 160 watts, amp integrated with RCA slots and integrated fuse. So i have a 2008 Mitsubishi Outlander LS, 6 Standard speaker with radio 140 watts. and i already have an auxiliary connection but it can only be used to play music from ipod, phone or any 3.5mm jack to RCA directly to the speakers using the radio as a medium.
Question is:
1. Can I still add the sub to the stock radio?
2. Will that fry my radio?
3. what are the adverse effect this can have on the electronics and warranty?
4. I will need major help if possible to get a diagram as how I can implement that with the stock radio.
5. Do you know if the stock speaker have connection for a Sub?

Your help is greatly appreciated

..by the way, I got this sub free..

thanks,

I just purchased an 2006 Infiniti G35x Sedan with the Bose Radio, was wondering if anyone would know if it has preamp out? And/or is there any resource I can go to online to find out what I can or cannot add to that system? I don't want to redo the whole thing, but would like to add a sub ( and amp? if need be ) without going crazy in labor..Thanks

For adding sub woofer you need adapter that converts speaker output into RCA connections. For this you need power amplifier and speakers etc.
