Never Seen Better For The Money

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.

great amp

I have this hooked up to some pioneer speakers I bought here as well, and they sound unbelievable. Plus its alpine quality so you know your not getting cheap stuff.

Best 4 channel for the money, *****

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!

good buy

a bit large for the power output, but the sound quality is fine, it has not overheated or had any complications. if you have room for it, I would recommend it

Great amp for mids, highs

I just bought this amp off a buddy of mine for the speakers in my car, and this amp helped my speakers compliment my JL w7 so well. Highly recommended

Makes my speakers SCREAM!

Bought this from sonicelectronix, and have it hooked up to polk momo 6 1/2 components in the front and 4x6 momo plates in the back. I absolutely love how it makes them sing.
