I used the program WisISD to help me with this box. Dual 12" kicker Solo-baric L5 ported box.
L=35 W=21 H=13
each chamber is an optimal 2.75 cubic feet. I might change the dimentions a litle bit, ive got to size check everything for my car before i draw it up on RHINO and see how i can incorperate a flush mount amp rack, flush mount cap compartment as well as a double baffle top to flush mount the subs for protection and a sleek look. Any other suggestions
