HI, I have a 1992 Crown-Victoria with the premium sound system. I'm trying to add a CD player and have bought the wiring harness adapter.

My problem is that there is no sound to the speakers, however the radio powers up fine. I'm guessing that i have to bypass the amplifier.

Can anyone give me an idea how to do this without running new wires to each speaker? I searched but came up with nothing.

Just to clarify,

You are replacing the factory radio with an aftermarket one right? If so are you sure you have all the proper connections on the harness, as well as the antenna cable?

When I bypassed my amp, I had ordered a whole wiring harness from Crutchfield. I had to disconnect the wire harness at the amp, plug the aftermarket Crutchfield harness into the amp harness, run the aftermarket harness through the car and under the carpet, route it around so it wouldnt bee seen under the dash, and bring it up to where the radio resides. Did that all w/o a problem and it worked out fine.

yup exactly what sep just said, its also refered as a reverse harness if you need to ask anyone at your local audio shop.

its a PITA process but its the only way it will work. either that or just get new speakers and amp \:D

I didn't have to bypass the amp in my 1989.
Did you connect the amp turn-on wire when prepping the harness?
