There is NO AMP in a 1991 fleetwood. It has amplified speakers. All it has is some fuses in the underhood fuse panel and a relay in the fuse panel.

Answer
Do the speakers sound distorted or do they whine ?. The diagnosis depends upon what type of sound that they make.



I can e-mail you a full set of electrical schematics and diagnostic charts to tell and show you how to test to see if the problem is within the radio, a wiring problem or a speaker problem for your radio but you will have to contact me at:
