In my 92 z28 it has the bose premium sound. The previous owner who i cant contact because i got it at a dealer had an aftermarket deck as far as i can tell because there is an adapter plate in place. But he took the deck when he traded the car in so now it has no deck and my pioneer wont work with the bose speakers! I HAVE NO STEREO!! Best buy people say the only way around it is to rip out all of the old speakers and wiring and replace it all. What can I do that dosent involve that. Is it likely that I could even find a factory cd deck for this car that will work with the bose speakers?
