We just inherited a very nice 94 c280 from my father-in-law with the stock Bose system. It sounds pretty damn good, but I would like to get a little more low-end. I checked with the local Meyer-Emco and they said they knew of no easily added subwoofer due to the wiring of the Bose system. Anyone with any other ideas? I don't need super high-end, I'd like to add a relatively simple powered subwoofer if it could be easily incorporated.

I posted something in regard to adding a CD changer on the general tech board, but probably should've posted it here. The car is supposedly pre-wired for a CD changer, and has the CD button on the face plate. I bought what is supposed to be a plug in unit from Crutchfield made by USA SPEC. It certainly appears to be the correct unit with the 10-pin rectangular adapter, but I simply have not been able to find the corresponding connector in the trunk. The only open connector is a three pin square connector I found on the right side where the 10-pin is supposed to be. Any ideas on what this plug is for, and any further details on where to find the 10-pin?
