Don't buy this amp, go with the aq2200d. This amp may push out 1300 watts rms at 1 ohm. I had mine connected to 2 15" CVX dual 4 ohm and it only pushed them as hard as my MB Quart raa1000... not much. Upgraded to the aq2200d and will never look back. Save up and buy a better amp.

Very clean amp and has great sound. I would recommend this amp for a nice install and great power, for pushing some subs, 10 or 12's. Kole has been around for along time and they rock in the older days. So buy one, cant miss.
