Car side of wiring harnass not making good contact
I found my problems in the Mach 460. The adapter was bad but it would also seem that the speaker harness on the car side is messed up. That may be why there was issues with the original adapter. The bad car side messed it up. What is the best way to fix this. I can half plug in the adapter and wiggle things around to get all the speakers to work but not once it is fully plugged in, I lose good contact. I know the wires are still good because i can make everything work but the female plug on the car side of the stereo for the speakers seems to be messed up. Tips tricks?
