2005 Pathfinder sub

Hey guys. Need advice on a sub config for my 2005 Pathfinder. Key elements I need: 1) Saves space. I carry lots of crap for business by folding down third row seats so I can't have it going across horizontally blocking storage space. 2) Be nice, clean and crisp bass. A stealthbox-type deal would be the best on the sides but neither JL Audio or MTX make one for my model/year. Someone suggested i get a box that portable so I can disconnect it and take it out when I need to save space. Any suggestions? Help greatly appreciated!!

If your just looking for crisp bass, You can always just put an 8" or a 10" in the back in a small box. you can screw the amp to the wall and just take the sub box out whenever you need the extra room...this gives you a little more freedom of choice than a vehicle specific box does...'89 Mercedes-Benz 300E

Blowing up in a car accident doesnt worry me, as long as I'm putting out some major dB's when I die...

I used to have a golf and had two IDQ 10"s in there and sounded heavenly. Going for mainly SQL. You think one 10" or 12" in a huge pathfinder will sound adequate? Thanks again.
