Hey 80, I need a design..

[TechSys]

Vehicle = 1989 Chevrolet Astro
Electrical and amp = SoundStream XXX-6500D on 16voltscharging at 19.5volts
Subs = 4 SoundStream SPLX-154 quad 1ohm 15"

RMS Power (Watts) 1000
VOICE COIL DIAMETER (INCHES) 3
VOICE COIL IMPEDANCE (INCHES) QUAD 2 Ohm
WOOFER DISPLACEMENT (FT3) .13
MAGNET WEIGHT (oz) 192
FREQUENCY RESPONSE (Hz) 20-300
Fs (Hz) 34
Qes .388
Qms 5.041
Qts .360
Vas (Ft3) 2.31
Xmax (in.) .565
SPL (dB) 90
HOLE SIZE (INCHES) 14.25
WOOFER DEPTH (INCHES) 8.125

Preferably a wall, somewhat like what I have now, but louder.. hehe. For info, here is a pic of what I have now



It only does a 146.7 average 30second bassrace run. I think, with a better enclosure, it could be in the mid 50s, but not positive on that.

Let me know if ya need any more info.

Edited: I forgot something. The maximum H x W x D is 44x50xUp To 50
