    Quality blew me away. I installed for years but the power is just simply incredible and absolutely 0 distortion if you follow the manual and have quality speakers. I am running fosgate tweeters and Polk 6 1/2 and 6×9’s in rear with an old 600w precision power with 1 15″ hifonics warrior.

    I bought this amplifier to replace a Pioneer 4×100 amplifier that had a HORRIBLE engine whine problem. Installed this amp and the problem is completely fixed. This amplifier also has a much better crossover then the Pioneer one did. Also extremely fast shipping, I’m so glad the seller decided to use Fedex instead of UPS. UPS is extremely unreliable and actually lost a $380 subwoofer I ordered.

    This amplifier is amazing! The sound quality is excellent! True Rockford Fosgate sound. I replaced a Taramps with this and the sound is night and day difference. I won’t look at any other amp’s in the future for my mids and highs.

    I have purchased and installed more amps than I can count. I have always had plenty of volume in my cars. What makes this amp special is that wired as a 3 channel amp it drives my subwoofer to the hard hitting base I could never obtain from cheep amps that claim to have more power.

    This is so loud and clear through my infinity 4ohm references in my Silverado. My audiophile friends all give it a resounding thumbs up

    Been owning this type of amplifier since the 80’s …my first amp was a punch 45 then a 75 , all the way up to a punch 150 ! They have always been great but I must say better with time !! A plus

    After debating with myself over removing or not the Harman Kardon system in my Mercedes, I did it along with installing a modern Android head-unit. Besides the fact that if you don’t do this kind of modification of the entire system, you won’t get the full benefits of a DSP enabled audio system, the sound quality is much improved. I also replaced the speakers with two sets of Infinity Reference 6.5″ component ones for the doors and a Kicker sub-woofer driven by a kicker single channel amp. The CLEAN technology did work unexpectedly well. the power is plentiful (probably 2 1/2 times what the original system was) and the sound is finally NICE. Also for those who might wonder what kind of music I’m into, it goes from opera to rock and oldies… I highly recommend this amp as I don’t regret owning it.
