hey, im looking for a box consultation/design for my golf. currently, ive got two 12's in a 5 cube box subs up port forward, bolted where the rear seat used to be. i'd like to get, 1)my rear seats back and 2) more output, same equipment. the subs are pioneer premier ts-w3001 4 ohm and the amp is a hifonics hfi2000d. i wouldnt mind taking up most of the trunk, just as long as i could fit the box through the hatch. box would have 34-36 hz tuning and be double baffle, with ample bracing. i dont have the precise max dimensions, but i know from the backseat to the trunk wall its 24''. i can get the rest of them later if you'd like to do the design
