Pioneer Double 12" Subwoofers + Custom L Ported Box!!! (jl, alpine, sony, vibe, fli, fusion, kicker) ?

I have a dual 12" Pioneer Subwoofer setup housed in a custom L Ported sub box. This setup is LOUD! I could be heard at least a quarter of a mile away on 600 rms between these subs (on 300 watts rms each) and they were ridiculously Loud for 2 entry level pioneer subwoofers. Subs model Number - Pioneer tsw1208d4 12" x 2 Custom Box - Made by a friend of mine from Car Audio Security The box is 3.5 cubic foot tuned to 33hz. It hits very Loud. I will also chuck in some 10awg speaker wiring for you. Very well made box aswell with bracing and properly sealed joints, all glued and screwed together very well.
