Best 18" Sealed Sub?

so your pulling the back seat(s) out? what is the maximum airspace you can get? for a couple more cubes you can go ported (maybe 6-7 cubes) and probably have much "louder" results and still get low.

I'm leaving the back seats in. I'm going to totally get rid of the middle seat in the front and make a box that goes from as close to the dash as I can get it to the front of the back seat and possibly step it up so part of it can rest on top of the seat and have the sub fire up or forward.

Something like this very crude pic. lol. (just try to ignore the commas)
