Well figure I might as well show the forum, this is the start for me. American Bass VFL extreme 12" subwoofer on Hifonics Brutus BRZ 2100.1D wired down to 1ohm running 1400watts rms. box is about 3 cubic feet with 36hz tuned port. Bumps pretty **** hard was running off a Rockford Fosgate t500.1bd nice amp but wanted more power got that BRZ and my sub slams. The video doesn't do any justice, ask me any questions I get bored so I'm on here a lot. I can get more videos as well. I'll use a digital camera so hopefully the bass can be heard.
