Problem with Saturn Factory Radio

I have a1991 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 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.

Double check again, find out if the sound cuts out on am/fm, cassette or only on cd. If it is cutting out only on cd, there is a problem with the channel in the cd player, a problem on the input channel on the back of the head unit or more likely a problem with the cd changer cord - may be clinched or have broken wiring. If the sound is not present on all 3 sources, then DYohn is probably correct.

Hi,

Thanks for the replies to date.  To clarify, the right side cuts out on AM/FM, cassette and the cd changer.
