I'm usually pretty good at finding these things but I can't seem to find a single 12" shallow mount box for an 08 Supercrew. Any help/suggestions? I just sold my 2 12" P2's and I'm trying to maximize my back seat so 2 12's is out of the question. I'm getting a shallow mount P3 and can't find a box.

 

mtx thunderform. you can get just the box or loaded with a sub, built in amplifier optional also.

 

The one that I saw was for an extended cab and didn't sit underneath the seat. Do you have a link?
