Sub box design for a Double cab?

i just got a jl w6 10 for my double cab 2002 tacoma, does anyone have a sub box that fits in their back seat?

 

Look up above in the stickys section and find Mr. Marv, extremely helpful in explaining stuff. I can not stress that enough, the first time i spoke with him i spent the better part of 30 minutes just explaining what i wanted from a sound system before he made any recommendations. I've also got speakers and mounts coming from him. He also builds sub enclosures etc. some of which may interest you.

 

I dont think there is a chance in hell of getting a driver that deep behind the seat in a first gen Taco DC.
