I've got a box you can have, but you'd have to pick it up. 3.25cubes @ 32Hz with 12^2 port area per cube. 15" Q that was in the wife's car that was totalled a few weeks ago.
I'm in Beach Park, IL but will be at the Frost Off show in Madison on the 22nd. PM me if you want it....
i actually have one built right now that was made to be used with either the Q or BL......... was made for a customer but he gave the wrong measurements
no sub has been mounted and was just made last week
