Crew Cab setup...yes a dead horse, but mine is specific
#14
I had my box built for my 10 behind the seat. I have not got it yet, but I am waiting. Ported boxed will hit hard with Hip Hop and rap, but when it comes to rock it wont hit as clean like a sealed box will. pro's and cons to everything really.

01-06 GM HD Crew Cab Dual Downfire Box
The SD-2 requires .5 for airspace sealed. The box is .6 minus the .08 for displacement that's pretty damn close to me. I don't think you will get a closer box prefabbed.
