I'm good enough with car audio to figure it out myself, I've done the system in my celica (with help), and in my audi I installed a line output converter to the stock bose amp and added a sub and amp to that. I actually just found a pair of used bose rear decks and picked them up for $50 in good working order so hopefully these last a few years and now I won't have to pay $150+ for speaker repair. Thanks everyone for your suggestions and info.
