I have a 1997 Toyota Avalon with 4 speakers (actually 6....2 speakers plus 2 tweeters upfront, 2 speakers in the back doors). I've seen reference to a factory amplifier located somewhere behind the glovebox, but I'm still not sure what I'm looking for. Can I tell from the wiring if one is utilized? I only had the factory amfm cassette stereo to start with. I removed it, but I'm still trying to find out if I have an amp hiding somewhere.

Any help would be greatly appreciated.

Cheers, Mike

One more thing: I just noticed that the wiring diagram in the vehicle database doesn't match up with the connector I have. Very few of the colors match, and I have multiples of some colors (white for one). There is a spare connector which I assume connected to a factory CD player, if I had one. Anyone have an idea what is correct?

Thanks, Mike

Latest update: I gave up trying to locate the amp, as I didn't really want to take apart the dash/glove box area just to find it. I went to BestBuy and purchased an amp integration cable (basically a cable with a Toyota connector on one end and dual RCAs on the other). I used this and completed the install in 30 minutes. The cable was kinda pricey ($17.99), but quick to use.

The wiring diagram database here assumes "no amp" on the wiring, which is probably not correct for most Avalons. Mine had just a basic cassette stereo and had a separate amp. Just something for other Toyota/Avalon folks out there. The wiring might be correct on the "output" side of the amp, but getting to the amp is a problem. If someone can offer advice on getting to the amp, it would be good to post for future installers.

Cheers, Mike

I'd also like to know about the amp. I have the 87 Avalon XLS with the basic factory AM/FM/cassette. I'd like to upgrade it to a unit that plays CDs/MP3/WMA/etc. I'd probably want to use the amp in the new radio, instead of the amp that is suposedly behind the dash.

Also, any tips on replacing the factory door speakers with better, and ideally bigger speakers?

I don't want to add any amps or speakers in my trunk, because I need all the trunk space I can get when we go on long trips.

OOPS. That's obviously 97, not 87 Avalon.
