Hey,
I just recently bought a 1987 5.0 LX and I was told by the owner that the radio tended to make noises at times. Well I didn't really mind not being able to listen to my radio at first, but now would like to try and fix it so I can listen to it. There's an aftermarket deck that has a CD player, speakers in the doors, and amp. I'm pretty sure that it's alternator whine because from what I read if the whine sound that it has increases and decreases with rpms then that's what it would be. It makes this whine when the radio is on and when a CD is in only when the engine is on, when it is off it sounds fine. I tryed unplugging the RCAs and listening for any sound and I heard none so I would imagine that the amp is grounded fine. From what I have read and understanded I need a noise filter/noise suppression kit. Wanted to get some input on this before I go and doing anything that I don't need to do. Any help would be great. Thanks in advance.

Problem solved. It was the ground for the amp.

What did you do? How did you fix it? I'm having the same problem...

you can also get feedback if you run your speaker wires and power wires together. always run speaker/relay down one side of the car and the amp power cable down the other.

How did you fix it?

I have the same issue in a '94 Convertible.
