thanks I wanted the box to be hidden (kinda) and wanted to keep the rear seat (06 impala). the top and back of the box are mdf so the subs arnt seen I play it and every one says where are the subs ? here are some pics of the rear seat and box connection

trunk false wall with rear seat folded down port in the middle (box top and back not on that is why you can see thru)

So does anyone here know how to know what size to use for each area of the box? I understand the design, just dont know how to know how much space for each section.
