I installed a new cd/tuner in my 1993 Explorer. None of the speakers work. If I hook up a speaker directly to the tuner, it works. But now none of the wiring works. It's like something got disconnected that affected all 4 speakers. It makes no sense. Am I missing something? I have the harness wired right and the unit gets power, just the wiring in the car no longer works. Any suggestions?
I don't follow you. There are 3 wires that I didn't connect. "P-Cont", "Mute" and "Ant". The power harness has 3 wires unconnected, two blue and an orange. How do I turn on the factory amp?
