First off this is in the enclosure section also. But couldnt decide where it belonged more so threw it in both. Dont hate on me for doin it, i just wanna make sure i get this right.

Well I'm about to build a box for a 02 Tahoe gettin a 18" d2 loaded fi btl triple 1" slug motor. Thinking 44"w 15" h 33" d. 10" wide port 7.5 cubes tuned to 31, may change it up to get 30 hz for da loz. But is 7.5 a little high for it?

Or just figured this one up 48" w 33d 16h 11" wide port l2 of 20" 6.8 cubes tuned to 30 hz 23 " of port per cube(thats not to high is it dont wanna get port noise badly). Maybe that would be better.
