I just bought 2 15" Fi SSDs w/ copper coil option. I was wondering which box type would yield better results.. sub back/ port back towards the hatch, or sub up/ port back CRX style.

In a 2dr blazer I've had good luck with sub up port back when running a single 15 apxx with 3500rms on it in a 4 cuft @ 38hz enclosure.

Until now Ive always had sub up, port back in my Bravada. My Mag is now fired toward the hatch and I actually like the sound of it better. I guess its all personal preference, though.
