I'm gonna have to test this 'heavy modification' theory one of these days. I'm sure theat ther eis an easy way to splice into the existing wiring to take full advantage of the existing amp and speakers. Once that's done adding an aftermarket amp to use teh existing wiring shuld be childs play.
Godd job with the CD Changer though. That sure makes it much easier.
