Description

The Prime R2-500X1 is a full-range class-D mono amplifier, capable of operating at 4Ω or 2Ω 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. Designed for subwoofers, a variable infrasonic filter and remote level control allows you to tune the bass to the desired level for your music. 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 - and with the included remote level control, you’re in charge of your bass. 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 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!

What a surprise!
Just wanted to chime in and confirm what others have already mentioned. I bought this little amplifier back in August and it is absolutely phenomenal. I have mine pushing one dual voice coil 10" shallow mount P3 Rockford Fosgate subwoofer in a vented enclosure inside my 2021 Chevrolet Colorado ZR2. The amp is not even breaking a sweat. In fact, the amp had to be turn way down because it was over powering the factory Bose system. It's THAT loud! I've impressed my family and friends alike with the power that this thing makes. For a minimal investment, it REALLY has woke up the rest of my factory stereo system. I highly recommend this amp to anyone who wants a reliable and powerful amplifier that won't break the budget. ... show more

Excellent Amplifier
I took about a year to write this review because I really wanted to get a feel for the product before I said anything about it. I don't have anything negative to say about this amp. I'm not running a competition system by any means but it power my JL 12" sub very very well. With all the adjustment options that it has. The signal sent to the sub is very very clean. The sound itself is very crisp and precise. Theres no distortion whatsoever. The sub that I'm running has an optimal rms of 300 watts, which is right on the sweet spot for this amplifier. As long as it's tuned properly and with a sub that's within it's optimal range, this amplifier is absolutely fantastic. ... show more

Very high quality. Came with a certificate and was rated at well over 500.
Great amp. Really woke up my 97 tj. I am using it with a single fosgate M2 10” I’m not into crazy bass so I’m extremely happy. Straight forward installation

Fantastic Single Sub Amp
Easy to wire and install, produces excellent power to drive a 'Pioneer A-Series TS-A3000LS4 12” Subwoofer'. Matches perfectly with resistance and output for this speaker. Price point hard to beat with RF quality.

Great sound from a TRUE 500 watt Amp
This amp works great coupled to my 2 Fosgate 12's, the wattage rating is a true rating unlike most of the no name/off name brands that try to sell you a 1000 watt amp for 150, This Fosgate unit has a true wattage rating not like the cheap brands that don't tell you the distortion levels on theirs are above 30% at the advertised wattage. Save time and money and get this Amp ... show more

Entry level…
I have been a Fosgate fan for decades and considered it to be my second favorite. I think I have a change in heart. I run 1, just 1 10” Kicker L7 in its Kicker manufactured ported box. It was powered by an older model Kicker CX mono amp (only because I had it for 6 years) and it dominated in sound! Fast forward to 3 days ago I decided on trying something new from Fosgate and what in the blue hell was I missing?! Granted new amp new sound but this little but heavy guy woke that L7 up!!! I never knew it was asleep! That 10” L7 craves power and this so called entry level 500 watt claiming amp gave it 604 watts! People I have demoed it for could not believe that only 1 10” sub could sound like that!! Well I am going to venture out and add a second L7 just to disturb the peace! I’m sorry but this amp is not entry level! First place for sure!!! ... show more

I have 2 P2 12s it’s a good amp not enough power to really push 2 12s P2s work good with one without distortion

You really can’t beat Rockford or kicker…..
Easy install!! Just remember it needs an 80 or a 100 amp fuse like mine to run properly.
