IIRC, the Ford factory amp is expecting a pre-amp type signal from the stock radio. An aftermarket radio like a Pioneer CD player has it's own internal amplifier and it can send the wrong signals to the factory amp. Some of that depends on how the new radio's wired into the harness. I'm no expert on the subject, but I'm pretty sure that's the case.

Some places sell the factory amp bypass wiring as a harness you can just hook up. I seem to recall seeing some threads on here before talking about a "no sound" issue with aftermarket radios.

Sorry I didn't respond sooner...didn't see the thread.
