let me know...i'd be glad to help you outYou do some nice work. I may have to hit you up for my box. I am going to need a box custom fit for my Magnum. Probably around 4 cubes at 38HZ for an HDC315, sub up port back. I am thinking if I should go with aeros or a slot port. Will be getting sub in the next few weeks, already have both amps (AQ2200d and AQ4X90). I want to sound deaden before I build the box.
