1998 Chrysler Sebring Convertable. How do I bypass my amplifier?

Okay. I own a 1998 Chrysler Sebring Convertable and for the stereo system there is an amplifier built in underneath the passanger seat, mine doesn't work and the one I bought for a Replacement doesn't work either. I was wondering if anybody knew where I could possibly get the wiring system or whatever I need to by-pass the amplifier so that I can just connect every speaker straight to the stereo. Please if anyone can help me.. I'd really appreciate it, I've been at this for months.

And.. we did check the fuses. everything is fine, the person before me did something to ruin the wires under the seat and they are water logged.

Therefore I would just like to know if I can bypass the amp and just hook the stereo straight to the speakers.. and if so, where can I get that wireing?? and a diagram to help me with it.

Any questions just email me at christine.presto@Yahoo.com with subject title.. "car info".
