Air volume question.

[Hbtank]

7Im looking to add a kicker 43CWR152 comp r behind the third row seat of my 01 expedition. Due to space issues I want yo use the Sound Ordnance BB15-150S. The kicker specs state minimum volume for a sealed box is 1.8 cubic feet. The SO box is 1.51cubic feet,Will this slight difference hurt the sub?

dude don't do it those so boxes ****.. they are tuned wayy to high.. do u have the sub already? we can help u find better sub but not a 15 in a box that should have a 10 in it.. u would be much better off getting a better 12 in 1.75f box than a 15 in a box way to small tuned at 45 hz or so..

I think it's a sealed setup...

It's def not gonna sound good as your hoping due to choking the sub and it's below recommendation requirements. Sell that one, and get a few smaller ones. How much space do you have to work with?

sorry ht u should get a nice 12" sub u can get a ok 1.75cf ported box for a 12 (box is really 2cf total) or 1.25 cf sealed for a 12 both probably better than 15 that will hardly move..

Thanks for the help, I haven't bought anything yet. I want to add a sub but keep the 3rd row seat in my expedition. The measurements are around 24inchs high x 15 inches deep x 30 inches long. The depth of the box is proving to be the issue. Im not looking to rattle other people's cars but i do like the music loud in this here band. Any suggestions on a box sub combo i would appreciate
