Awesome

This amp powered two 12" alpine type r subs in a sealed box. I have never in my entire life heard subs that hit that hard. This amp is a must for anyone with type r subs. I've had kickers, and a cerwin vega stroker that was awesome, but these alpines with this amp are outstanding. Be sure to buy a power cap because lights will dim

BAD A** AMP

If you're looking for an amazing quality, high powered amp, look no further! This amp has some serious power! I hooked it up to my JL 13w3v3 and this thing doesnt even break a sweat! Iv had no problem standing up to people with the JL 1000/1 amp, I love this amp and will continue to go through JBL for any amps in the future!

DAMN

I just installed this amp on 2 12 L7's 2ohms and DAMNNNNN! I think the birthsheet said 1448 or somewhere around that matter. Yea its a oversized amp, but its worth it especially if you don't wanna buy the fancy name stuff. Overall, I give this amp a 4.5. saves money and this is a dang good price to get it at.
