We recently built and installed a box to hold two 12 inch woofers under my rear seat, worked out pretty well

also had a hard time decided on what i wanted to cover it with as carpet being my last choice, so i came up with spray on bedliner, i think it blends in with the interior well

 

Nice work on that box, is that a sealed unit or ported? Do you mind posting the dimensions of your box also?

 

it is a sealed enclosure, a ported box requires too many cubic feet for this application, as it is it sticks out from under the seat a bit, but still plenty of room when the seats are forward

i forget the measurements off the top of my head but i will get them and post them

 

Nice work. What kind of subs, amp, and most importantly, how does it sound?

 

2 cadence ultra drive 12s and a cadence ultra drive 300w amp

and it sounds great, it really suprised me with the down firing of the subs, this is the first time i had ever postioned subs this way

 

Looks very cool man.
