Ok so here it is...i want to put 2 re sex 12's behind my back seat in my 03 f350 crew cab..i know i have to move the seat forward and im planning to move it 2 inches up...the box i want to build is gonna be 44.5Wx14Hx8.5D thats the external size and the internal is 43x12.5x7 which leaves me with 1.8cuft after dissplacement..what i want to know is, is this a good idea? do you think it will work? if not what can i do to make it work? and no dont say make a wall or tear out the back seat because my parents wouldnt let me do that, im lucky that they are even letting me do this. im buying all the equipment from here http://www.advancedcarcreations.com/main.htm they are an authorized dealer for what i want thats why im going through them..also if you do have a better idea in subs they have a list of all the dealers they sell and i would like it to be from one of them. so and help or constructive critism would be appreciated!
