93 Audi S4 - No Left Front output from Bose speaker. This is a reoccurring problem with the Left Front speaker not having any sound. We have found the stereo and Bose amplifier to be in working condition when sent for bench test and repair. There may be a wire problem from the amplifier to the speaker. If your stereo is experiencing this problem, please bring it by, no charge, and we will post new instruction help for this problem. Thank you.
 
2000 +/- S4 - Poor AM Reception One strange problem with this system, the screws securing the antenna amplifier were loose. Tightening the mounting screw completed the ground circuit and took care of the problem. The Antenna Amplifier is located on the rear driver's side roof pillar, behind the panel.
