Clean Class D on Highs - VALUE

I have been a Rockford fan all my life. They represent QUALITY and set standards. I am proud owner of power and punch series amps. Now I have prime to cover all the lines. This amp, being a class D for one, on highs, is not the same as AB but I can tell you that you REALLY NEED TO KNOW YOUR SOUND to tell a difference. 99% probably wont. There is a difference when it comes to comparing prime to punch and to power. If you don't own a power series then you won't understand. But when you do it's obvious you have something special. Prime is great, having this r600.4 on RE XXX 6.5 components up front and Infinity Reference in the rear, you get plenty of power and a clean signal. If you are tight on your budget and want VALUE matched with quality then this is a great choice.

Great deal

Definitely would recommend really good quality and easy to use.

Best amp I've owned

Big brother to my R400, I have the R600 powering 2x8 inch bazooka tubbies, and 2x10 inch bazooka marine tube subs. Incredible depth, clarity, and volume. Factory tested at 820 Watts RMS. I cant imagine how loud this would be in a car - it fills my 39 foot boat with sound.

A year powering my setups, great amp!

This amp is a dream! Well worth the price. It's reliable, clean and efficient. For my first setup I used it to power polk db's (2 components in the front and 2 coaxials in the back. Those speakers were monsters. I upgraded a few months later to polk's high end MM series. I only installed two front components for my sound stage and I'll tell you, I push it to the max all the time and still receive VIVID clarity, sound quality, and power from the combo of amp and speakers. This amp is versatile! So if you decide to switch it up like I did, as long as you do your research (and your math) this amp is unbeatable.

Great Buy

Have always been a fan of RockFord since the early 80s truly dependable and way underrated. I would recommend this amp to anyone from novice to expert.

AMAZING

just an all out amazing amp, have had it for about 2 months and have never had a problem. Puts out great power

Good amp

Bought this amp and hook it up and dam this thing is a beast you should buy this amp for your highs price was good happy with this amp

Power house for an entry level amplifier

Do not underestimate this amplifier just because it's Rockford Fosgate's entry level Prime series. This little guy packs solid lows and clean highs that will scream through your Mids and Highs. I have this amplifier running full range speaker configurations but I'm sure it would run moderate subwoofers fairly easy. All in all if you're in the market for a solid 4-channel amplifier I would highly recommend this product!

Save Your $$ and Buy this Amp!!

On strong recommendation from another seller for a less than $200 amp I bought Zapco 4channel 75/channel amp, and in less than one year started having problems. I bought this amp from Sonic a month ago and I wish I had saved my $$ and gotten the R600 instead. Its a noticable step up in power, particularly running at 2 Ohms/150/channel with my Image Dynamic CTX compontents and ID8 sub. Like the rest of the reviews, I have much bigger, clearer SQ, soundstage separation and especially midrange sound coming from more power.

AWESOME

LOVE THIS AMP, COMPACT, SOLID, WELL BUILT, VERY EASY TO INSTALL, NO CONS

Clean - Nuff Said

All I can say is wow... just wow. Clean sound, compact design, and even when, like the other Class D amps, ran hard barely breaks a sweat. Although it might be paired wrong with some speakers I've never heard of they still pack a punch for uncommon. Either way this amp does pack some punch, love it.

well pleased

This amp is effin awesome. Running polk db6501s and a bridged mephis 10 sub. My jeep sounds ridiculous now. Delivers booming bass and still can be tuned for any kind of music. Worth every penny.

love this amp!!

Its worth your money. Amp gives out clear and loud sound.

just wow

Me and the my brother have been putting in car audio for a little while and I'll tell you something, this amp is the most clean I've ever heard in my life. I've never heard rockford amps before but now I understand the hype. I will buy rockford again and recommend to everyone. And in the picture it looks small but it's pretty thick to be honest. But still compact.

clean sounding and true out put

this amp rating are true and you can trust it sounds clear and doesnt get hot plays for hours with no problems

Good ole Rockford

Over the years Rockford Fosgate has continually surpassed my expectations. I've been trusting in RF for over 20 years now. This prime amp is a "prime" example of why I've been a loyal customer for so long. It's supposed to be the "value" series of their products but yet it performs better than most other premium lines of manufacturers. It's small yet powerful, performs at a surprisingly cool rate, represents at a very clean ratio, and is versatile yet simple to dial in. Once again, I am one very happy camper and you will be too. Can't go wrong with Rockford Fosgate!
