Here's the deal. My bandpass wall is almost complete (build log soon) My rear chamber dimensions make building a 6th order difficult and so I've resorted to just a 4th order. 22.75x42.25x34.5 are the internal dimensions of the rear chamber. I would do a 6th order but trying to cut down that much cubic feet when I only have 22.75" deep to work with is a pain and it's almost the same deal if I built a 4th order. I could go about 8" deep but that still leaves me around 6 cubes, and that's more than I need for 2 15's. My question is, would I benefit anything if I had the subs in seperate enclosures angled inward? Like a mini V except only for the rear chamber? I would still have the front chamber with the loading/port wall behind the passenger seat but the rear chamber enclosures would be facing each other and the subs will load off each other.

That's the basic shape of it, minus a few angles from the wheel wells and what not. It would be shaped the same way for a 4th order also. The drivers are Mach 5 Audio SPL 15's

I never thought about making a labyrinth style port for the rear chamber so it might work out now...

Yeah, I'm using pretty much every contour in my Jeep so I have quite a bit of room too work with. about 25+ on the front chamber. I didn't want to do a labyrinth style port on the rear chamber because I like L's better but I would have some dead space inside because of how shallow my rear chamber is.
