      What a Beast !!!

      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

      Great Amplifier

      Great quality! Excellent sound. Nice and compact. Fits nicely under my truck seat! I bought Rockford Fosgate because you know exactly what you’re buying and it does what it says it does.

      Is ok…

      Is ok… Will probably buy an AB amp for my highs instead.

      Rockford Fosgate and Amazon have terrible customer service

      1st I would like to say Amazon is changing. Just like everyone does. Customer service not the same. Now that they are big. The don’t care. I bought this amp intending on installing ASAP. Then had to put my vehicle in shop. Vehicle was in shop for more than 30 days. Out of return window. Went to install amp. Right out of box. Amp in sealed plastic. It absolutely doesn’t work. Amazon won’t take back or exchange. Warranty with Rockford fosgate is terrible. The said I had to send it, pay for shipping and then it would be 2 months. I am beyond fuming. This sucks all the way around. I’d just like to thanks Amazon and Rockford for nothing. Remember Amazon. Don’t get cute. We the people can shop a lot of other placesUpdate!!! Amazon finally made it right with me. Thanks Amazon. Rockford you still suck!

      Worst amp I Ever used

      This is possibly the worst amp in my 40 years doing this line of work. I first tried it on 3 channel too weak to play… then I went 2 channel and went in to protect at under 10 watts or 70 decibels.

      Great sound quality and build quality

      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.

      Excellent!

      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.

    14. Eric

      If your thinking about it just do it already.

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

    17. P. Kay

      Just buy it!

      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 finally have the base I always wanted.

      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.

      Started smoking within min. of using for the first time!!

      See that little white cloud next to the RCA’s in the front? That’s smoke! Hooked up, correctly, and it started smoking nearly instantly!!! Bought another brand of amp and hooked it up to the same wiring and no issues – works wonderfully!Buyer beware of this one. Wow!

    23. Thomas Moyer Jr

      Awesome amp.

      Awesome amp. Sound quality is amazing

    24. Outdoors in Fl

      So incredibly clear and plenty of power!

      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 initially bought a budget 8" subwoofer unit from them, and my expectations of its performance were unreasonable. I decided to upgrade to a 12" and they readily accepted my return and promptly prepared the 12" for me. Very happy with my purchase! I Would definitely recommend doing business with the folks at DDF. :D
