I have the base Pioneer system in a 92 SC300. I'm looking to upgrade the rear amp. I'm not really wanting to change the head unit. I've searched, and have not been able to find a wiring diagram for the rear amp under the CD changer. Any help/advice appreciated.

Also any input will be appreciated on replacing the speakers with something mid range in cost.

Wow, who would have guessed? 3 different units.

P6800 is what mine says...
