Hello! welcome to justanswer!
Does the buzzing sound stay at the same volume as the radio?
Can you still hear the buzzin if you tun down the volume all of the way but still have the radio on?
I tried unhooking the battery for about five minutes, and sure, enough, only the back speakers continued buzzing, followed soon thereafter by all of the speakers, although the radio and CD changer were clearly working. The sound is more of a loud popping sound when the ignition is turned on.
I'll try the procedure a few more times, but please send me the procedure to remove the AMP and refer me to a place that repairs them. Thanks.
Ok, below are two links. One has the AMP removal instructions and the other is a link to a site that can help you in repairing the AMP.
