I have 18" high by 38" wide by 20" deep to work with. Using 1" mdf and the measurements of 18x35.75x18 the internal volume is 5 cubes. How can I build a vented 5 cube internal volume enclosure tuned to 35 hertz with the sub mounted in the middle of the box (kickers reccomended size and tuning? Maybe I should pay someone on here to design it. I'll be sending it 4000 watts rms from a memphis mojo. I'd love to hit 150 db as long as the box doesnt destroy the sub on daily use.
