I'm having a problem getting a straigh answer on whether or not i can install my two 12" kove subs into my 96 aurora.  The problem is I have a factory bosse system with the factory cd changer.  According to a few places I've called my subs cannot be added without a new cd player or getting rid of the speakers in the back.  I think some of the places are just trying to make me buy a new cd player.  I also don't see why I would have to get rid of the back two speakers to add two subs.  Any suggestions would be greatly appreciated.
