This Amplifier amazes me

I am an electrical engineer and typically the larger the amp the better (meaning more MOSFETS, dual diodes, heat/thermal dissipation and other pre-amp electronics) When I first received this smaller amp I was skeptical. I put it on a 12" DVC 2 Ohm Punch and I couldn't believe it. Rockford Fosgate did their research on the circuitry of htis amp and that research paid off. Worth every penny, I have actually bought another one of these mono-blocks, a 4 Channel amp, Component Speakers, an 8" Subwoofer and several other products now all made by Rockford Fosgate. If you are on the fence then believe me, I have designed electronics for a living for 25 years now, this amplifier will not disappoint.

As advertised.

So far so good. Everything I expected from Rockford. Hopefully I get Long life out of the product.

Knocking hard!

Hot Amp in More Ways Then One

This is a very user-friendly amp. The instructions were very precise for connecting and calibrating. It also helps that it looks nice, so it’s a great display piece. My only issue is that it gets really hot so placement is crucial. I didn’t mount or run the remote because that’s above my pay grade. Gonna go with a professional For that.
