12" under seat subwoofer enclosure in 02 CC

[fishv12]

Good afternoon,

I recently purchased used at a killer price an amp/sub/box combo which had a 12" JL W0 sub. With the sub instructions it specifies a 6.5" mounting depth and 1.5 cubic feet airspace. Now after some research all I can see for my truck is 10" sub enclosures. Fitting something any bigger than 10" on the back seat is impossible but under the seat would it be? Could I build a custom box that would fit my requirements have have it down fire with enough room for the sub? Then again I can't seem to find any box with enough mounting depth room for my sub.

Any help is greatly appreciated. I am quite efficient at building cabinetry so I am thinking about tackling the problem myself but it just seems like my sub is going to be a problem.

I have a Jl13w5 under my rear seat in .8 cu and it works very well sub requires 2.75 depth.

Take a look at this thread. Look at all three pages. whitetrash21 posted the box design he is using for a down firing sub. You might be able to figure out a way to make it work. Just keep in mind you do need at least half an inch behind the sub (in the box) and enough clearance in front of the sub so it doesn't bottom out while playing.

Thank you gotdsl actually this even gives me some dimensions to start with. He used a 10" sub witch was 6" deep but at half an inch deeper I am sure I can make it work by simply adding half an inch to his dimension. Even if someone feels the box through the seat at that location I don't really care as I rarely have someone sit behind me. It might be a little tight on the sides as mine is a 12" sub but it should work. This really gives me more than I was expecting so I really appreciate it.
