custom fiberglass boxes

[Bigcat]

I'm interested to see if there is one to fit a 03 Denali. I want to keep the third row and would really be interested in a way to hide two 10"s in the truck although this idea comes in a close second. Probably easier/ less expensive to accomplish too

That would be sick but the only problem is the rear HVAC.

Where's the rear hvac?
