anyone have a simple sub up port back design sitting around for a DC lvl 3 15?

Ok so I was gonna try my hand at aeros ( never used aero ports ) but I just don't think that's gonna be ideal, its going in an suv max dimensions are 36 wide , 20ish tall , and as little deep as possible would like to stay around 18 deep or less but I have some wiggle room, I keep playing with it in torres but I fear I'm over thinking it and making it more complicated than it really is because I've been researching t-lines and bandpass boxes now I can't figure out a simple design for a slot port for this bad boy ... It will get about 1100ish RMS , thanks in advance for any help but I'm going to keep playing with it so maybe I can figure it out

What is the required air space for a DC level 3?

Says 3-3.5 with 15-16" port per cube ... Was hoping around 32-34 Hz tuning

Ok so I came up with a few possible designs but It just doesn't seem right to me , I feel I mist be doing something wrong, as soon as I get to a truck stop where I can get wifi ill upload the pic so maybe you guys can tell me what I'm doing wrong, like I said it just doesn't seem right , like my port is taking up much more airspace than it should for one
