98crewcab Posted January 31, 2010 Report Share Posted January 31, 2010 (edited) break it down to rectangles and squares. the angled part make a square and divide it by 2 to get that volume. give me a minute to draw up something to explain........... ok, excuse the crude drawing....something quick. L X W for each "box", then L X W for the imaginary box (angled one) then divide by two. add up all your square inches and multiply by your highth to get your volume by cubic inches. divide by 1728 to get your cubic ft. hope this helps Edited January 31, 2010 by 98crewcab Quote 06 2500hd, 6.0L, 4l80e, 4wd, (muah work truck) 7" BDS HC lift kit (5) 37x13.5R18 Toyo Open Country M/Ts (5) 18x10 Moto Metal MO962 tablet in lieu of deck blue tooth interconnect to soundstream eq (for volume control and bass control) 4 Alpine type r 10's 6 cubes net, 80sqin's port, tuned to 33hz 2 brutus brx5000.5's 2 pairs 3" polk audio for a pillars 4 pairs polk audio 6.5 comps 1 pair 8" polk audio for mids 2 xspower d3400 batteries.....learning alot from meade and his circle of some of the baddest installers ive seen- thanks guys, for not being so cocky and posting the way it should be done!P.S.

98crewcab Posted January 31, 2010 Report Share Posted January 31, 2010 every thing in the box labeled with L x W is box. the port is everything unmarked........

alvitae Posted January 31, 2010 Report Share Posted January 31, 2010 To make the angled part easy you could use the wedge enclosure calculator at 12volt.com. Quote Link to comment Share on other sites More sharing options...
Boon Posted January 31, 2010 Report Share Posted January 31, 2010 That's effectively a choked tapped horn anyway... doesn't calculate like a normal box. Quote 10.x volts fo' life! Link to comment Share on other sites More sharing options...
