WHINE IN SPEAKERS

[GRAPEAPE94]

I have recently started to get a noticeable whine in my speakers when listening to my XM radio. I have a ground loop isolator installed. The whine is there even with the engine off and the key in the run or acc. position. I do not have the noise when listening to the AM or FM on the radio.

Unplug the audio cable from the XM radio and see if the whine goes away. Try plugging it into a different audio source (a phone is best, when it is not plugged into a charger) instead of the XM radio and see if the whine is there then. Try plugging a set of earphones directly into the XM radio and see if you can hear the whine then through the earphones.

Those steps will help isolate the source of the noise.

Found the problem. Dumb luck. Checked every connection for the radio, cleaned them all and after putting everything back together the noise is gone. The sound now comes through clear as can be.

I was getting worried there for a bit, I thought that you had a new SO, and that might have been your problem.
