yeah iv kind of narrowed it down to the deck .. the gm decks these years have allways been plauged with issues .. has any one tryed to hook a aftermarket deck to the bose amp with out a interface . it seems that with most of the adaptors out thee there taking the preout from the new deck and through the adaptors wireing sending that signal to the bose amp . iv seen a few that also allow u to use that decks speaker outputs to . most seem to be limited to 3 volts max preout and im guessing since most newer decks have 5 volts or more alot of the noise issues are related to that .. i guess i could allways pull the bose amp add in my own amps to power the speakers . even though the bose speakers are of a lower ohm rateing im sure if i dont drive them too hard i wont over work the amps too much .. like i said im not to worried about loseing the chimes or the onstar . but i dont want to spend a bunch on a interface and have it give me issues . or noise . plus my daughter keeps reminding me that my new truck is lacking a dvd for her since my last one had one lol
