Planing on new build

[xanoreita]

Been planing on a new build for some time and looking for some advice on aeros and sub facing.

This is what I'm thinking about to get when having some extra cash:

Subs: 2x Ground Zero GZRW 30SPL, 12", 1000 W rms ( http://www.ground-zero-audio.com/english/05_rw30spl.htm )

Amp(s): 2x Titanium GZTA 1.1200MK² ( http://www.ground-zero-audio.com/english/08_ta11200mk.htm ) OR 1x AQ2200D, havn't decided which one should I get, AQ seems cheaper than the GZ ones but ofc it would cost some more cos I'm from EU.

And heres the current box design and this is where I need some advice, thinking 2x4" aeros with lenght of 10" but the port are per foot seems kinda small...should I put 6" aero instead of 4" or what? And also which one would be better, subs up port facing to cabin or trunk or subs and ports facing to cabin and sealing off trunk?

Sealing off the trunk would be better. Also go for the AQ amp.

And, what is the port area per cubic footyou have with the 2 4" aeros?

last link has pic to box calc and sketchup but anyways, box calc is saying 6.25

Your port area per cu ft is a little small. I would shoot for 8-12 in per cu ft. Might have to use 2 - 6" or 3 - 4" ports. Everything else looks good.
