For your sake I hope this isn't true, but a car audio worker at Circuit City has told me that in most Bose systems, you have to rewire everything due to the original "Bose-exclusive wiring." Granted, he may be full of [you know what] but the system that he suggested for the replacement of a Mazda Millenia's Bose system cost a pricey $750 including installation. Not to mention that this system that was replacing the blown Bose system wasn't even Top-of-the-line...
