I originally ordered this amp to push 2 12" v-max dual 4. O man. It pushed those babies hard and they took the power. I then sold the Cerwin's and went with 2 12" orion XTR-PRO dual 4ohm. And lemme tell you, those xtr blew the cerwins out the water. The orions are sum beefy subs. And i wired it dwn to 1ohm on the onx and it plays them LOUD N LOWWWW. Luv the glossy finish. After hour of beating the orions up, the amp is still kool to the touch. Higbly efficient indeed. Nice features nice look and power to spare. My only gripe is the power and ground terminal, would be nice if it were 1/0 but instead its 2gauge LAME! So i had to cut a lot of copper off my street wires power and ground. Other than that, GOOD AMP.
