Strereo wiring question (93 Camry) - Toyota Nation Forum : Toyota Car and Truck Forums

Beaver · 02-18-2005, 03:15 PM

I've got a '93 camry. I want to put in an aftermarket cd player as it only has a tape deck. I don't know if I have "premium sound" or not, I haven't looked too closely but I've got a tweeter in the door armrest, fairly large speaker in the door, speakers in the rear and possibly some others. I haven't owned the car long and when purchaseing it sound was not a high priority.

So, I pulled out the deck and went to buy a harness adapter and was told they don't make one. I was told I have to find my toyota amp and wire my new stereo into that. Is this guy shittin' me or do I really need to wire straight from my new stereo to the amp?

IF you have premium sound the amp is usually mounted in the trunk on the underside of the rear deck between the 2 rear speakers. i cant remember how to wire your stereo directly to it though.

Nope, the OEM amp for the Gen3 is under the passenger seat.

Beaver, it sounds like you do have the premium setup since you have the extra tweeters in the doors. A positive check is to see if you tape deck has both Dolby B and C noise reduction. If that's the case, then it for sure, it's an OEM-amped system.

my bad

Judgeing by the mismatched bolt holding the stereo bracket into the car and the mismatched bolts holding the stereo into the bracket I'd say it is not the original deck. I would expect that by '93 premium sound came with a cd player as did my dads Celica w prem sound.

Could I not take the 4 speaker outs from my new cd player and hook them up to the existing wiring in my dash and be done with it?

Yes, there is something amplike under the pasenger seat. I did not have a close look at it last night while I was dicking around with the stereo.

I would get a decent aftermarket CD/MP3 player and yank out the old amp, and run new speaker wire off the new cd player. That's the best way to do it. There should be another harness behing the tape deck that is prewired for the non-premium stereo, you will have to get the wiring harness kit and wire it into that harness.

What's your budget for the new CD player? And are you also thinking about new speakers?

I've got a JVC cd/mp3 player to install in place of the stock deck but what do I do about the speakers. There are 8 in the car but outputs from the JVC for only 4. It's been a long time since I took any electronics butas I recall if I parallell or series my speakers into twos I will get an impedance mismatch resulting in power reflected back at the final amp stage of the JVC. If run hard it could cook. That'd suck.

I'm hopeing I don't have to buy new speakers. It's my wife's car but I drive it occasionally so I want decent sound. I don't need stellar sound, that would show the limitations of many of my mp3 files.

Yeah there should be another harness in the back to bypass the stock amp. When I installed my deck I just bypassed my stock amp which is located under the passenger front seat and took it out.

Since you aready have a good cd/mp3 player I would just look into upgrading the speakers. Is there a certain budget you are trying to stay under for some new speakers? As for the wiring you would just hook them up like normal, pos from the deck to positive of the speaker, and same for negative. Each speaker to its own channel(4 speakers total). If you are on a budget then just look into replacing the speakers with coaxial speakers. IF you don't mind spending upwards of 3-400 dollars then what I would do is get a 2 channel amp, and a decent set of component speakers for the front, and later on if you feel the need then to replace the rear speakers with decent coaxial speakers and running them off the cdplayers rear channels.

This thread might lend some useful info.

I have no intention of changing my speakers. The ones in the car are good enough, I don't care that they are not the best speakers on the market, they produce half decent sound and that is good enough. I can't crank the stereo cause I usually have 2-3 kids in the car, sharon lois & brahms sounds bad on good speakers.

All I want to know is how would you connect 8 speakers to 4 channels?

S13/R32 · 02-21-2005, 12:14 AM

8 speakers to 4 channels - well forget the wiring harness toss that idea out the window, all my years i've been an installer i've never used a harness unless its one i've made up for running mutiple amps, i would just simply solder the wires together, with a bit of heat srink.

now back to ur 8 speakers im guessin u have a wagon... now u sed u got tweeters in the doors and another speaker in the doors, so there should be a cross over for those speakers so u should have only 6 speakers to install as the tweeter and the other speaker in the door run on the same chanel unless toyota have done something stupid and frustating like runing every speaker and tweeter striaght to this amp under ur seat.

from wat i can tell u, u have some options-

1. if there are cross-overs with the tweeters wire up four speakers to ur head unit, then if u wanna get the other 2 speakers working asumming u got RCA preouts on the back of ur head unit buy a low power 2 channel amp it don't need to be expensive or powerful as most factory speakers aer like 30-50watts max. a second hand amp would be a good donnor, then u got the cost of a wiring kit.

2. now as u probly kno its not a good idea to run more than one speaker off one channel but with RCA's u can split no problem, now with this u will probly have to cut and solder wires of a RCA cable i wouldn't axactly recomend this but hear it goes...

get an RCA lead if ur head unit has two RCA pre outs get two, figure out the inputs and outputs of the factory amp like which audio input make wich speaker work ect.
get the RCA lead and wire it to the amp since u can splice RCA's u can wire in to 2 channels, so if u got 2 sets of pre out front/rear u can use the fade feature.
use the front preouts for the speakers in the front doors and the rear preouts for the 4 speakers in the back.

thats some options but u may find that the amp probly dosen't all of those speakers or it runs the back speakers and is a cross-over for the front something stupid like that

i hoped this helped ya not confused
