Great Amp, Nice compact design
July 10, 2008

Review written by Jeffrey from Gulfport, MS

This Amp not only looks good and is discreetly compact, but it produces some awesome results. I hooked this up to some Alpine components it it sounds amazing. I definitely recommend this amp to anyone looking for something to push 2 sets of Alpine SPX-REF components, since that is what I have.

The only down side IF I had to pick one would be accessing the gains. There is a door that you have to remove in order to get to them, and you have to use the right size Allen wrench in order to remove the door.

Nice amp tiny, great sound low on features
July 17, 2007

Review written by Kaushal from Des Plaines, IL

Nice amp, good sound quality, but no pre-output, and lacks features found on similar priced amps. Also cheap plastic on sides, and caps are also plastic.
