"Just bought one of these a few days ago, installed it myself, and man does this thing SCREAM! I'm already pushing 2 10" Kicker CVR's (on a seperate amp) but now I have some Infinity 6x9's, I had to put these things facing away from me cause they would literally make my ears ring! Great buy! Do buy one if you want your car to be loud."

One amp system 10/29/2007
By Timminator from Ohio

What's great about it: flexible, reliable, sexy
What's not so great: None to report

"I'm a die hard fan of 4 channel amplifiers. I've got the front channel hooked up to all four door speakers in my van with the high pass crossover protecting them from potentially damaging bass. The rear channel is bridged, uses the Fosgate's built-in low pass crossover, and is powering four 10" subs. This allows me to fade the sub in and out to adjust for songs with too much/little bass without affecting the bass balance w/in the music. Very pleased. Strongly recommend."

WOW!!! 10/20/2007
By TheMrBill from Skagit County, WA

What's great about it: Powerful
What's not so great: Ears Hurt :p

"I can't believe how well this amp performs. I bought it a month ago but couldn't install it until today...

I took a 1 1/2 hour car ride to the place that does the install. Let me just say that I didn't expect this kind of a difference... My 6 1/2" Alpine type S 2-way speakers were a perfect match, as far as rms goes. I used to turn my head unit volume up to about 21-26. It'd get pretty loud & then distort. But now, with the amp, I can only go to 14 or 15 until my ears hurt! The bass response is amazing, it truly sounds like I have a pair of 10's sitting in my trunk. I have no subs at all. And the clarity is still amazing.

Later, when I get subs installed I'm going to turn on the high pass filter. That way I can turn it up even more and totally destroy my eardrums :D hehe.

To sum it up, I was totally amazed by this amp. Waaay more than I expected. And, like all Rockford fosgate amps, my rms on my certificate was much higher than 50 watts per channel. I have to be careful not to blow my speakers I guess."

Wow.. 09/24/2007
By MECP from Hattiesburg, MS

"Rockford's amp's never fail to impress me I have this amp power 4 Alpine Type R Component Speakers and it sounds wonderful this amp puts out plenty of power for just about any full range speaker on the market. My specific amp had a test sheet with 1357 watts max power, which is about a perfect match for the Alpine's with a 330w max power rating for each speaker. The only bad thing I can say about this amp is its shiny black finish attracts dust easily."
