    i have this hooked up to 2 10" alpine type E subs. i would recomend this combo to anyone! i bought the subs on a fluke,but i believe the amp is everything. couldnt have picked a better amp! Just pissed i paid $600 for it 3 years ago! Infinity has my loyalty!

    I bought one of these a year ago hooked up to two Infinity Refrence 12" 1252w's in a ported box. Everyone tells me its the loudest 650w they've ever heard and it hits cleaner then anybody I know. You can hear me from a half block away with the windows up. I'm gonna replace it with something with more power but It's a great amp that out preforms its specs.

    I just got this bad boy in today and had my new system put in. I have it pumping into two 12" JL Audio W3v3's and it makes them hit like CRAZY!! Not only does the amp deliver, but how can you beat the price? MSRP is $459 and you can get it brand spanking new for $189? You'd be crazy not to purchase this beast.
