Dodge quad cab, box under seat?

I have a quad cab ram and I got a box from ebay that is under the back seat.  It was made of 100%mdf and is of great quality; no amp rack.  I got a pair of the audiobahn AWP310T compression piston subs to go in it (shallow moutning depth, which is a must in this vehicle).  As for those JL's I hope they're shallow and don't require too much airspace.  A fiberglass enclosure would give you more mounting depth.

I have a picture of the install I did at MobileDynamics over the summer with these subs.  They're here http://www.mobiledynamics.com/main/phoenix/pages/projects05.htm and it's 1/3 of the way down the page.  My amps by the way are under each front seat, minus the center console.   

ive rearfired those exact subs and it actualy outslams most other subs ive heard or done anyother way.  the box is definately not for amatuers though and it might cost bout 150 tops in materials to build.  just think about it and get at it...thats what i did. ive always known  anything is possible just might take some work.
