2002 ford mustang gt aftermarket stereo question
Hi I have a 2002 ford mustang gt with the Mach 460 stereo. When I bought the car it had an aftermarket head unit, and it still does. My problem is the driver side tweeter and the right rear tweeter are the only things that are working. Nothing else works. I need help to figure out how to get the whole system working? Please help any advice would be greatly appreciated.
