The Audi Q7’s rear subwoofer, OEM 4M0035621A, is a used Bass Box Speaker that adds low-end punch to the factory audio system. Also known simply as the subwoofer or bass box, this unit was removed from a donor Q7 equipped with either the 2.0L turbo four, 3.0L supercharged V6, 3.0L diesel, or the 3.0L mild-hybrid turbo V6. When the subwoofer fails, common symptoms include distorted bass, rattling, or no output from the rear speaker.
