$10 bucks more and one of these should work in that enclosure with very little trim out?

Or maybe one of these here. take a little more power, and cost a bit more and should drop right in that enclosure if you havent cut a larger hole.

i havent tried either one of these subs yet, but I have been looking at them closely to try out. just a suggestion for the space /enclosure you have. Now i have had a pair of the A,Bass ES Series 1044 on one my PPi Phantom 1000.1D and they did really nice in my nephews double cab 16 GMC truck.
