Ok, I made a prototype single 12" Box that fits on the driverside of the trunk in Convertibles....it as .94 cu feet of air space with 1/2 plywood(remember, just made it to test fit), now i plan on making one outta of 5/8" MDF. It leaves PLENTY of room for a second box on the other side and then you can mount amps in the middle....and possible still have room for a backpack or something for us "school kids". If all works out I will make up "Blue Prints" b/c everyone on this board is too lazy for too "MAKE YOUR OWN PRINTS". What is the big deal, you have to take measure ments to make the box anyway so y not post them? ANYWAY.....if it works i will post plans for ppl.

EDIT: IT IS A 12" BOX NOW BUT WILL BE FOR 10W6s....I only made it a 12" b/c my friend had a spare 12" and we wanted to try it out.... But that is only the hole you cut in the top, hell you could make this for a 5 1/4 semi- sub if you wanted....
