There is no square when doing boxes its cubes, so go out in the truck and measure your max dimensions you have for an enclosure (height x width x depth); then give us the numbers.

i feel really dumb for saying squared, ive had that drilled in my head all my life and i knew it was cubed but apparently i wasnt using my brain, ill put an update tomorrow of how much room i have back there for an encloser, i just got home and i need to go to bed. ill have it up first thing after work tomorrow

Veteran equipment for a mostly mainstream consumer, I love these.

I'll offer my advice tomorrow, PS3's suck at typing.
