Recently started having trouble with the rear speakers hissing, crackling, popping, squealing, etc., etc.
It happens intermitently whether the radio is on or not.
Adjusting the fade control on the radio all the way to the rear speakers results in no sound whatsoever from those speakers except of course for the hissing, . . .
It is an Audi Bose system and so far the only way I have found to stop the noises is to pull the fuse for the radio.
Any suggestions as to my problem(s) will be greatly appreciated.
