I have a 1991 Saturn with the original factory radio. The only modification made was to add a trunk-type cd changer.
The problem with the radio is that I am losing my right channel (both front and rear). It works fine when I first start the car but then I hear a "pop" from the right speakers and the sound disappears (when I turn the balance all the way to the right I hear a slight sound). Occasionally I hear another "pop" while I'm driving but the sound does not return. I suspect I'm also losing quality on the left channels...but since I'm closer to those speakers I can't say for sure.
I did have a new alternator installed in November. Do you think there is a loose wire (between the radio and the alternator) or is the radio giving out after all this time? (or something else)
Thank you for any suggestions you may have.
