this is another item i found in my garage cleaning from my 6. it is the rear shelf bose subwoofer. it worked fine when I took it out but not sure now because the large dust cap was lose when i pulled it out of the box. would at least be good to have in case you decide to trade and have gotten rid of all of your stock bose stereo. like i said no guarantees that it works!!!!! if intrested send me an offer.I'll ship for free.
