So I have this problem with my 1997 Toyota Camry were the back speakers have no sound at all coming from them. It has a replacement JVC head unit, but besides that it is all stock.

I tested the head unit and it is outputting a signal to the rear speakers, but it is not showing up at the end of the wire in the trunk. I saw that the 1997 Camry LE had a factory installed amplifier. I am thinking that is the problem, but I don't know were the amp is located.

Does anyone know how I can get to the amp? Also if there is a problem is there a harness I can get to bypass it?

 

If the radio has a remote amp, the amp not the head unit outputs the signal to the speakers.

If the radio has an amp it may be located under the front passengers side seat or far passengers side under dash area behind glove box.

Check radio harness, the head unit radio has shielded cables harnesses. The combo radio/amp unit does not.

To bypass the wiring run additional wires from the amp or radio to the speaker.

Wire colors are black and yellow (LH) and red and white (RH).
