My system does it also, I think it might be the rca's, if yours are silver plated, try some gold plated rca's..Mine are silver plated also but never changed them because i'm not really annoyed by the sound....
94 Camry stereo/amplifier question
I just had an aftermarket CD receiver installed in my 94 Camry, and I'm not happy with the result. When I turn the unit on, I get a loud pop out of all the speakers. Is the amplifier always on by default (no remote wire)?
I'm thinking about bypassing the amp, 'cuz the receiver does 50x4. Does anyone know the power output per channel of the stock amplifier? Also, can it be bridged for re-use as a sub amp?
Thanks!

The receiver does 50x4 max wattage, probably about 18-22 x 4 RMS. Your stock amp will most likely sound better than running it off the deck. I doubt you'd want to bridge it, if it's even possible.
Not sure what the loud pop is....usually it's due to not have a soft start on the amp, but since it's the factory amp, I doubt that's the problem.

What's happening is that whoever installed the radio is using the factory-amped harness, instead of using the harness to bypass the factory amp. The loud pop you hear is the problem resulting from the OEM amp not able to handle the source load from the aftermarket radio. You can try and put a 4.7K resistor inline with the blue turn-on wire and see if that cures it. Otherwise, just bypass the amp completely.
My car has no factory amp and i still get the loud poping sound when i turn the car off and on..could it be my equalizer?
Yes, anything within the chain of sound alteration can have bad effects such as popping noises. Bad or inferior RCA cables may cause problems too. Thus, it can be a very long process to determine and eliminate unwanted noises.
I should have mentioned earlier that I think I saw the installer put in a line-level converter. So, it's definately running through the amp at this point.
Aside from the pop when it's first turned on, the sound pretty much sucks all around. I'm thinking about taking it back and having them bypass the amp, but I haven't decided for sure yet.
Anyone know what the power output of the factory amp is??

what kind of head unit, and speakers are you using?
i have a 94 camry v6le and mine has the factory amp (but i removed it) the speaker read 15watts so i doubt the amp puts out much also my car has the 8 speake system it sounds alot better if you bypass the amp.
It's an Aiwa CDC-X504MP 50x4 head unit, and the speakers are stock.
I kind of figured the factory amp wasn't doing much. I think I'm going to take it back to Best Buy and have them bypass the amp. I'll probably upgrade the speakers fairly soon, too. Any recommendations for replacements? I don't want to have to buy a separate amp. I'm just going to drive them off the Aiwa head unit. I might get a small amp for a dedicated sub in the trunk, but that would be even farther down the road.

I've bench tested the factory amp, and it is in fact 15 watts/channel max, 11w RMS. It has the same type of amplifier IC's as an aftermarket deck but lower power, so you'll be better off using the power from your deck. Plus fewer components in-line = less chance of interference and distortion.2wickedtoyz said:i have a 94 camry v6le and mine has the factory amp (but i removed it) the speaker read 15watts so i doubt the amp puts out much also my car has the 8 speake system it sounds alot better if you bypass the amp.
If you just get the Metra harness for Toyota, you can bypass the amp. There are 2 blue connetors inside the dash to the right of the deck, they are where the output for the amp connects to the speakers. Unplug those and plug the standard Toyota harness in (after you wire it to your deck, of course) and you're good to go
Edit:
Harness on eBay
I have a similar problem with my 94 Camry Wagon stereo system, and I need help! First, does a 94 Wagon have an internal amplifier? if so, where is it located? My main problem is that during either warm days, or when the stereo is played too loud, the amps seem to cut out. The prior owner cut the internal wires in the dash, so I had to find each one, which I did. Everything sounds ok, until it cuts out. It acts as though it gets too hot (amps that is). I have a Kenwood 50x4 stereo, with 6 speakers in the car.
What can I do to eliminate this problem? I was unable to bypass the factory amplifier as I couldn't find it, or the wires going to it.

When you say you have six speakers, do you mean that you have a component set and another pair of speakers, or you that you actually have three pairs of speakers hooked up? If you have 2 pairs on the same set of amplifier outputs, you will be pulling a 2 ohm load from the amplifier, and most decks are only rated for 4 ohms +. The extra draw would cause extra heat and could cause the problem you are describing.mike_ballard said:I have a similar problem with my 94 Camry Wagon stereo system, and I need help!

I just checked my service manual and the factory amp is located under the front passenger seat in the wagons as well. If it's not there, you don't have one, and your deck is hooked straight to the speakers.
I have just the factory speakers, which are one in each front door, plus two larger ones in the rear hatch, plus two small ones in the side of the rear hatch. The stereo is a 45Wx4, not a 50Wx4 as I had thought.
Sounds like you may have found the problem, however, how do I solve it? Do I need to get a head unit that is capable of 45Wx6? or something like that? And I looked, no factory amplifier.

As a first step I would try unhooking one of the rear pairs of speakers and see if it solves the problem. There's no sense in spending money if it's not necessary. If that does solve the problem, you can either use only 2 pairs of speakers or use a small 2-channel amp on one pair and run the other two pairs off the deck. Keep in mind the factory speakers are only rated for 15 watts each though, you may want to consider upgrading them.
If I were to go the route of a small amp, where would I install it? Also, I assume you mean to unhook the speaker at the speaker right, not at the headunit? This has all been good information, and has been most helpful.
I'd assume the rear two pairs are hooked to the same channels, so you'd want to hook it to 2 of the rear speakers. i'd probably put it under the passenger seat, that way it's out of the way and your power/signal cables will be short.
Yes, unhook the wires at the speakers.

Is there a site I could get instruction on hooking an amp like this up? Do I have to run new wires to the rear speakers? If so, where are they? I know, I ask a lot. But I travel a lot and having a working stereo is a very nice thing. Where would you suggest I get the amp?
Try Basic Car Audio Electronics, they will have about anything you want to know. The 'amplifiers' page should get you started, and then some.
You would have to run another set of wires from the amp to the speakers.
For an amplifier, I'd say one of these would suit you fine. Legacy isn't by any means top of the line, and their output is overrated (just like most inexpensive car stereo producs), but it should be more than plenty for your application. I've installed the 300 watt version of that amp for a friend, and while I doubt it put out 300 watts, it worked great and he had no problems with it. The price is right, too. (Except for the shippng ) You'll also want an amplifier install kit, I'd just pick up the cheapest one from Wal-Mart, and maybe you could just get an amp there too.

So is that what that thing is underneath the passenger seat? cause there are a LOT of wires connected to it... more than any amp i've ever seen... (in my 1994 2dr)
