[QUOTE="Mr Cabinetry, post: 4078771, member: 571490"] OK, if I took what you gave up so far for the enclosure given what I've already done for the design the enclosure right now is at 7.56 cu.ft. - Not including the sub and other displacements. And since your going to be " tubbing out " the bed of the truck and you don't know at this point what you will or will not have to work with dimensions wise The best course to take is finish all the metal work in the bed of the truck and then design the enclosure to fit around that because given what the design of what the enclosure requires when all said and done, your looking at close to 8.0 cu.ft. total for the enclosure. But the real pain in the azz of the whole design is trying to fit 4 12" subs with ports with a 49" width x 14" height and trying to do it without wasting a sh!tload of area to do it to make it all fit. I'm just going to show what talking about purely from a concept perspective: [IMG]http://i29.photobucket.com/albums/c251/MrCabinetry/Various%20Pics/4cvx12sporteddraft.jpg[/IMG] Looking at the front baffle area given for the width working with, the subs would have to angled as such to fit them all and for the minimal angle to be used not to eat up volume and still fit the subs. Porting wise, best that can be done here is use 6 - 4" dia ports which is 75 sq.in. of port area. For the tuning Kicker spec's given the volume of the enclosure cal's out to 44 hz port tuning. Those 6 - 4" dia ports would be 10" long. The only thing unknown is the power, but, if each sub got 750 watts with those ports, there is no port noise. [/QUOTE]
