January 9, 2009 Never Seen Better For The Money

Allen from Hamilton, OH

I just recently bought this amp. I hooked it up to Type-R 6x9s, and WOW it gets extremely loud. I don't even have the gains half of the way up, and it's gets too loud where it starts to hurt your ears. The sound quality it produces is phenomenal. I haven't had any issues with heat. Setting it up was easy, and the controls were easy to follow.

Honestly, I can't see why anybody would buy another amp that puts out this equivalent of wattage. It's cheap, and blow-your-head-off loud.

I've owned more than a dozen 4 channel amps over the last 30 years and this amp is a winner! The sound is crystal clear powering Infinity Kappa 60.7cs in front and Kappa 62.7i in the rear. the highs sparkle at high and low volume and the gain is only at 75%. DO NOT MISS THIS DEAL!
