What exactly did you need help with? It seems like a good start so far (besides the port area being too small if your just going for SPL.)

Any pics?

make sure the front baffle is very solid and thick. also, remember on a wall for spl to tune a bit higher, and the box size will be quite a bit smaller than a box tossed in the back of a tahoe.

also on a wall.. make sure each sub loads the same way. if the sub at bottom is moving more than the top, it can usually end up with some cancellation, or even ruining a sub.
