Need a box design for 4 12's

[RHoughton1]

I have 4 dd's 1012 series. I have removed the back window out of my truck and connected the camper shell with a boot. I have walled off the side walls with 3/4 inch steel and 2 sheets mdf and I have the whole bed to work in.

Heres a pic of the old set up i currently run 2400 watts rms to all 4 subs and I dont want to cut metal.the bed is 48"wide 33" tall and 6'long the back window opening is 13" tall and 49" wide. I also compete in MECA if that helps.
