Ok guys I know this should go in the sounds and shine section but I need a quick answer. I have the Mach460 system in my car and one of the amps in the rear is blown. I went to have a new aftermarket amp and subwoofer box installed and was told that in order to do this the whole stock audio system needed to be ******ed out and replaced. Is this true? I thought you could just wire in the amp and subwoofer..
