Folks, 1998 Audi A4 with the Bose system. All the speakers have a garbled sound. Replaced the radio...still buzzed Next thought was cracked cones but when I took off the grill on the right front found it was intact. Is there another amplifier somewhere that might be causing the distortion. It really distorts at low volume. -- Paul Caouette sv Wild Iris (V40-133)
