Subwoofer

Do a search here in the forums, I found a replacement dual 2 ohm free air and used it on my old 01 deville. When my son's went in his Deville, we used a new surround kit on his sub. The surround is usually all that fails on these. That was the cheapest route, but both methods worked well for me. Also, some guys on this forum found a CTS sub that interchanges and is much cheaper than the Deville replacement to buy new. Since this problem is so common, if you buy used, you may need another one in a month or so. Been there.
