Took a while and a whole bunch of math to figure out the right volume to fit behind the seat. One jump seat is still completely functionable, and the passenger seat can slide all the way back if they want comfortably. It's 3 JL w1v2's powered by a 500/1 JL amp.
The box is sealed, and I filled it a little bit with 2x4's to give me a volume around <2 cu. ft inside. I was a little skeptical about having sub's on different sides of the box, but it came out great and sounds even better.

3" BL, cranked TB's - 31" wheels(soon to be 33)
yea, the person in the jumpseat is gonna get punched in the face with bass haha... i'll work on getting a video up, right now the truck is at the half way point with a body lift so it's a little immobile for now
