Reccomend me a box based on these T/S specs

[I Like Waffle]

Got my 4 15"s in and they have no mf reccomended box size. I had 2 ported in about 5.5-6 cubes @ 34 and liked them alot, loud as piss . I was thinking 11-12 cubes net @ 34hz for 4 of them, trunk car so subs and port will both be up unless i can figure something else out, was also thinking of port forward? Ive heard bad things about port forward for whatever reason though.

T/S -

Power - 600/1200

Sensitivity - 90

Nom imp. - 3.5ohm

FS - 25hz

Qts - .53

Vas - 3.8

VC - 3 inch 4 layer

Thats all i can pull up right now, what can everyone reccomend for box size based on that?

I didn't know piss was loud. I think shits are a in the middle and they are louder than pisses so where does that put you? lol

Lol but if you liked what you had before, double it and tune it to 34 again? Sounds pretty logical if you liked it before.. I might actually lower the tuning to 32 or 33 but that's just me.

what did you hear about port forward?

A while ago when i first signed up for the site in 05 i remember reading a big discussion on port orientation, and everyone generally decided that port back was always best, something about port forward interfering with the spl in the cabin or cancellation. Something along those notes, i mainly just remember that it was determined port back was the best for whatever reason, so ive always tried to go with subs back port back, or subs up port back.
