Would 4 Oa 15s work in a 14 cube box?

[Based]

So at first I was gonna do 2 18s but now I realize I wanna do 4 15s. Just one problem, unless I go over my window line an inch or two (which I don't wanna do, I wanna stay flush), I'll only have 15 cubes after wood. No subwoofer displacement because I'm inverting them. With the aero port(s), it's gonna come down to around 14 cubes, maybe even more I don't know how to design boxes...

Would they still do well? recommended max from Obsidian is 3.75 per 15, 14 cubes is like 3.5 cubes per.

Or maybe I should just *** it and go over my window line?

And also, does port direction really matter from like a truck to a car to an suv? Like people say the port should up fire in trucks and back fire in trunks and whatever. I'm in a truck, so should my port be up?

Ok I just ordered the 4 15s. I'm excited. Next thing I'm buying is the alternator and battery I'm gonna be using. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif//content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

What vehicle is it? Most SUV and hatchbacks are great subs up port firing back. Some pickups are good both firing up, or port to the side. Obsidians are great subs.
