I have a Alpine CD player in my 1996 Mustang GT along with the stock Mach 460 speakers and amps. When listening to music the drver speakers will go in and out. but not completely off. But when the r working the passanger side is louder. Much cleaner sound. The back ddrivers side speaker is barely working. Does anybody know if this is a speaker problem or a amp problem or even wiring? Bestbuy did the installation of the deck. Thanks for your help stangnet.
