I have this connected to 2 12 inch Rockfor Fosgate T1's. They are loud as fuck and the neighbors hate me.

I have this amp running 2 JL w3v3's in a ported box. The amp is 3/4 of the way up and it slams hard. This amp is a monster and for what has it priced at you'd be a fool not to buy it. This amp hangs with the big dogs with a tiny price tag. Ive owned Hifonics amps before and they cease to amaze me time and time again.

I have this amp hooked up to 2 apline type E. Everyone knows that's low grade subs. And it will make ur eyes shake. And the amp is less then half way. Great amp
