Hi everyone, I recently bought 2 Hifonics BRZ15D4 Brutus 15 just to see what they will do and I wanna build a blow through for my truck, and I need help designing it, I'm not sure about woofer displacement and port area. Each sub requires 4 cubic f/t. I'd like to tune the box to 32 or 33 hz. Something low so you feel it in your chest, I don't wanna go to big on the box so I can still use 6 ft of my box.

I have the basic box planned out. Right know I have enough room for 9.58 cubic feet and that's without port area and sub displacement. Is that to much?
