Hey guys....I have a quick question. I am new to the car audio hobby and I have a Ford Fusion with an old JBL GT150 amp. I have put in a Sony Xplod XSL123 and it sounds good....but weak. It is in an old sealed box from a home theatre that is no longer sealed....and definitely not the right box for a car trunk. Anybody have any ideas on how to make a Super loud ported box for it?

Parameters of Sub

Fs-22.6
Qts-.54
Qes-.65
Qms-3.20
Vas-4.47
Mms-158.4
Lvc-1
Xmax-4mm
BL-11.2

Thanks!

Those T/S parameters can't be right... and if they are, it's a pretty ass-like subwoofer.
