im wanting to add the premium sound to my 04 model, ill use my own amp/headunit, but id like the factory subwoofer if i can get ahold of one, there are plenty on ebay for $50-60 but dont include the interior trim.if anyone wants to do away with theirs and wants the non-premium sound side plastic parts, im willing to do a trade+ ill give some cash, if the subwoofer is blown thats fine too, ill replace it.matthew
