You already have the subs? I'm thinking you are going to want more airspace for 4 of them!

[bn020]

yes already have all 4

[kam311]

Well I'm thinking you don't have enough room with the stated dimensions for 4, is there no way to get more room out of your hummer??

[RickyFriery97]

with those dimensions, you have 12.68 cubes, gross

after sub displacement, it knocks it down to 11.84

not to mention port, and bracing disp.

dont think you have enough for all 4
