Looking for help with enclosure

[xanoreita]

So basicly I don't understand a shit about calculating wat kind of enclosure I need so wondering if someone could help me out.

Ported box is wat I'm looking for.

So I have 2x 12" Ground zero Titanium GZTW 30T

GZTW 30T details (copypasted from GZ homepage):

diameter: 30 cm / 12"

power handling: 400 WRMS

impedance: 4 ohm

voice coil: 50 mm / 2"

excursion: X max. 14 mm / 0.55"

resonance frequency: FS 25 Hz

SPL: 87,8 dB

my trunk details:

Width: 37 inches max

Height: 16.1 inches max

didnt bother measuring the lenght, got enough there.

if any other details needed, I'll try to give em.

those subs kinda suck but can't afford better atm

thanks
