sub ?

i know i work at a stereo shop lol it is impossible to get the correct amount of air space for all four 12s to unload in a reg cab mazda

I used to run 3 JL 12 w 6's behind the seat in my Reg cab. BUT I also did some " massaging" of that stupid bump on cab back wall !! 50.5 inches long - 21.5 inches high 11" at botton and 6 " at the top.
About 3.5 cuft

hey im not arguing the fact of air space or the stupidity behind my answer of the 4-12 but that is what the kid wantd so i sqeesed them in there for him i dont like the idea of it but that not my truck or my choice he wanted it done i made it happen...
