Description

Built by Fanatics…For Fanatics! Truly a line designed by fanatics for fanatics, our family of products are developed by the same people that use them in their everyday lives. It’s the Rockford Fosgate commitment of passion, power and performance built into everything we produce, connecting enthusiasts to their music and machine. Best of all, our entire line of products are designed and engineered in Tempe, AZ, USA! The Prime R2-500X4 is a full-range class-D 4-channel amplifier, capable of operating at 4Ω or 2Ω stereo, and 4Ω bridged/mono and rocking 500 Watts of RMS power. This amplifier is extremely efficient because of its class D technology, which reduces demand on the vehicles electrical system. The amp also features C.L.E.A.N. circuitry to help you adjust your gain settings and the unique P.O.W.E.R. supply continues to generate more than the rated power as the voltage increases. The Prime Series was developed for car audio fanatics that want a reliable amplifier that won’t break the bank – with all the power and performance you’ve come to expect from Rockford Fosgate. Rockford Fosgate amplifiers are renowned world-wide for being “under rated,” easily surpassing all specifications, and most importantly, generating more power than their ratings. The latest generation of Prime Series amplifiers are also designed to be easy to setup and configure, making them perfect for use with factory audio or custom aftermarket systems. The Integrated Punch EQ corrects the acoustic deficiencies in the listening environment, by delivering up to 3X the bass via equalization. Rockford's integrated level setting technology called C.L.E.A.N (Calibrated Level Eliminates Audible Noise) is our patented circuit with input and output clip indicators that help match the source unit to the amplifier and optimize musical output

  • Perfect amp for everyday use Perfect amp for everyday use
Just like the title says because this isn’t in a show or competition sound vehicle, just in my everyday driver(2003 Mitsubishi Montero Limited) 75X4 it claims to push I highly doubt that, more like 100x4 because I had to completely redo the settings on my radio including doing away with using the loudness settings, even after working and fine tuning the C.L.E.A.N setup, I feel like my truck should be in a sound competition, I have it running a set of Punch P165-SE 6 1/2 components in the front doors and a set of Punch P1675 6 3/4 3way speakers in the rear doors and it is mind numbing the amount of clarity and non distortion it’s putting out, birth sheet says the total RMS power is 580 which is still jaw dropping ... show more

  • Friggin' Love It!
It's been years since I've heard my sound like this. I actually bought this to replace my Pioneer D-class 1200w amp. The sound coming out of my speakers sound soooo clean, and powerfull. I have this installed in my 8th Gen Honda Civic (without a 2nd battery) but I do have this paired up with a Rockford Fosgate Digital Compacitor. All of my speakers are Rockford Fosgate full-range 6.5 speakers, but I also have tweeters installed (Pioneer). This amp doesn't seem that it sucks up too much energy from my battery, which I was aiming for. I had that issue with the previous amp I mentioned. I went with this amp also because I used to have a mono amp that drove a sub box I had, so I knew what it could do (I now have a powered sub installed in the spare tire. I wanted my trunk space back lol). But IF I needed to buy another one of these, I would. ... show more

  • Well Put Together
Well known brand with a solid product. It is well put together. Has all the proper documentation with test results. As input LED and outpet LED so it makes it easier to set levels. It may be a bit on the pricey side for three hundred thirty bucks, but if you want quality it is worth it. I have it powering 4 CT Sound speakers. ... show more

Amazing amplifier, louder than the rating, crystal clear audio, diy install; bring your own cables. This brand’s amplifiers are the best and hands down our perform any amplifier in their class. I have two in my car one running since 2013. I cannot express how great this product is.
