not enough airspace? bigger system ideas?

[YZmoto125 10+ year member]

So right now I have kind of a dilemma. I have an 0615L7 with a ZX100.1 hooked up to it in my nissan titan extended cab pickup(******* doors model). Right now, with the windows down, it puts out pretty good bass, but once i shut the windows, all that goes away, which i think is due to it not having enough airspace inside the cab? Dadly, right now the box is sealed, and I plan to change that this weekend, and get it in like a 3-4ft3 ported box(thats all i have room for), but will it still just be chocked on air?

Also, pretty soon I plan to upgrade my system. Its loud right now, but I want louder, a lot louder. I plan to get a zx2500.1, and im still not sure what to run off of it yet. I was thinking 3 12L7s, 2 15L7s, or 1 12" solo x. With this, i would shave off the 60 side of my back bench seat and turn it into a 40, then build a fiberglass custom console between the seats. What I wanted to know was will I just end up with the same small amount of bass till i put the windows down? Its getting cold here in minnesota so thats not really an option. So of these options, which one would you choose and why? and yes im gonna get kickers, so dont tell me to get different subs.

yea the L7s love big boxes,but 4^ft should be ok for the 15"

You might be having some sort of cancellation in the cab. Try changing the way the box sits and see if you can make the sub face a different direction.
