I need help on getting the cu. ft. for a box with 4 dimension. Actually before I get into that I am planning on putting in 2 15" kicker xpl's and powering them will be a jbl 1200.1 amp. which I found at etronics.com to be the cheapest, 309.99 for the 1200.1. The speaker thermal power handling is 600 watts each and there max on an enclosure is 2.7 cu. ft. the box that I plan to put them in is 37.5w x 18h x 19d1 x 12d2 and that is external. The wood being used is all mdf 3/4(heavy!!! there goes my gas mileage) It also has a center divider. so how do I get the cu. ft. from this box and if the box comes out being to big, would factoring in the speaker displacement make a difference? Thanks for the help in advance.
