My radio didn't work when I bought my car. The premium sound system stereo had been replaced by a cheaper AM/FM factory model.
When I took out the radio, I noticed there were two sets of wiring harnesses. One set goes with the premium sound and wires to the amp, the other goes up into the dash (I guess Ford installed both sets of harnesses on all cars, one for premium and one for standard?). The latter works, and powers four of the six speakers. But I checked the premium system wires with a circuit tester, and they don't have power.
Does anyone have any suggestions on why the hot wires on the premium plugs wouldn't work? Do the hot wires get power through the amp, and if so, does this mean the factory premium sound system amp is toast? I'm stumped.
I'd like to return it to stock with the factory premium sound system rather than getting an aftermarket system, if for no other reason than to avoid giving would be thieves any more incentive to cut my top or break my windows. The thought alone makes me cringe!
