My bose subwopofer in my MY2003 996TT has stopped working, it was making a slight distorted/crackling noise then in my attempts to stop the crackling (banging the top etc- not too hard) it stopped working alltogether now. rest of system works fine but sounds **** w/o the base. is there anyway of fixing it or anyone an idea of what has gone wrong and how to fix it? thanks
