You have to take into account the displacement of the subs, but the formula is LxWxH / 1728

that will give you cubic feet.

go to kicker.com and find your sub on the site. they will have the driver information listed below (eg, sub displacement/volume)

HMMMMMMMMMMM

I just bought a box off of ebay

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...&category=14945

and on their it says its 2.9 cubic foot

I did that lil

LxWxH / 1728

which is

27.75x18x17.5 = 8741.25/1728 = 5.05 Cubic foot (using the bottom width of 18")

27.75x12.5x17.5 = 6070.3125/1728 = 3.51 Cubic foot (using the top width of 12.5")

Which ones correct and why is their site wrong?

:dunno:

You should have gone to math class ;) j/p

My calculations say that box is 3.25 cf before sub and port displacement. With that design you can't figure out the internal volume by just multiplying length width and height. There's more to it, but I dont feel like explaining...there site is right though, and if you have anymore questions feel free to ask
