I have the stock subwoofer and enclosure from my 2007 wrangler unlimited. It is in near perfect condition (there is a scratch on the plastic but it is only cosmetic) and it fits 2007-2010 wranglers and wrangler unlimited. The wiring harness is intact and was not cut during removal. Just plug and play!
I am in Atlanta, and as far as I know it will be a perfect fit in any 2007-2010 jk or jku, I am not sure about newer jk's because they changed it a bit back there. Maybe you could get it in with some trimming
