Availability: 17 in stock

Primed for Performance, the R2-500X1 is a 500 watt, class-D amplifier capable of operating at 4Ω or 2Ω mono. 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, a P.O.W.E.R. supply that generates more power as voltage increases, and integrated Punch EQ that corrects for acoustic deficiencies while delivering up to 3X the bass. Perfect for subwoofers, a variable infrasonic filter and remote level control allows you to tune the bass for the desired level for the music.

      More power than you think

      Actually, 650 watts. A sheet comes with each fosgate amp. They test each one, cool that it’s underrated.

      Great product

      Really nice amp (on the right). Came with a birth sheet of 630 WATTS RMS! I have it powering 2 JL audio subs and it does it well. No complaints. Rockford fosgate never lets me down. I have been buying their amps since the 90’s.

      Amp is very powerful! And the C.L.E.A.N helps so much when adjusting amp.

      This Amplifier amazes me

      I am an electrical engineer and typically the larger the amp the better (meaning more MOSFETS, dual diodes, heat/thermal dissipation and other pre-amp electronics) I bought an R1 model of this amplifier and it absolutely amazed me. So I bought the R2 as well and I have to say these amps are so efficient, clean and worth the money. The electronics in the pictures are of the R2 amp, the difference between the R1 are the heatsink hold downs (which are better), a few of the electrolytic capacitors, the stand off board that wires to the main board and just the actual dimensions.

      Rockford fosgate never lets me down

      Sound quality is awesome, and the bass knob is great when you don’t want bass all the time. Great value for the money!!

      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.

      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

      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.

    18. Amazon Customer

      It rocks!

      This amp rocks. It’s compact and puts out clear sounds. It has no problem pushing my 500w sub.

    19. Shane

      Rocking little amp!!!

      Small and powerful. Running 2 Infinity slim 10’s at 2 ohm and they are pushed hard. Sounds great as a mono amp.

      Hot Amp in More Ways Then One

      This is a very user-friendly amp. The instructions were very precise for connecting and calibrating. It also helps that it looks nice, so it’s a great display piece. My only issue is that it gets really hot so placement is crucial. I didn’t mount or run the remote because that’s above my pay grade. Gonna go with a professional For that.

    21. Chris

      Rockford rms is always under-rated.

      There’s nothing to dislike. This amp is amazing. Everything I needed and more.

    22. Jose

      Bad product

      Best part is the power controller knob

      Bought this to power a jbl 12″ I got on black friday for $30. Couldn’t find an amp I trusted for ~$100 so I bit the bullet and got this RF amp. It’s in my old 98 C1500 and is great! They send a spec sheet from factory testing. Easy to wire up, easy to tune with all the CLEAN IN & CLEAN OUT lights on the amp. Great amp for my small setup. It’s pretty small compared to amps from 10-20 years ago.

      Premature failure, no solution.

      Failed within 6 months. Seller will not honor the warranty, and Rockford wants me to pay to ship it back, sit there for weeks or months to be repaired and then pay to have it shipped back to me. Poor quality, poor service, poor warranty procedures. I’ve been a long time loyal Rockford customer, but after all the money I’ve spent on their products I think its time to take my business elsewhere.

      It’s a Fosgate product, you get what you pay for.

      What’s not to love about a Fosgate product! My wife bought me this for Christmas and when I opened up the box I was happy to the Birth Certificate said 630 watts of peak power! I am truly impressed with what this amp can handle. I currently have it installed in a 2006 Chevy Silverado and I am pushing a Kicker L7T 10″ and I haven’t even maxed it out yet and I am blown away with how great it sounds. I used a 4 awg Kicker Amp Install Kit and it all worked out perfect. I would recommend this Amp to anyone who is looking for an amp that does what it says it will and more.

      Lil bad bush

      Not impressed for the price!

      I had a skar audio amp running my 8″ jl audio zub in my jeep but the amp was to big to fit anywhere so I bought this Rockford Fosgate amp that would fit hopping it would replace the skar amp and fit properly. Unfortunately even tho they were the same cost the Rockford Fosgate was not even close to the same quality on sound to the sub very distorted and just sounds cheap. If you have room go for a better amp like a skar audio.

    37. Bzom-b

      Worthy of the name

      I have this amp pushing one kappa comp 10 inch 2 or 4 ohm sub. I’m running 2 ohms at 645 amps in a sealed box. It makes that sub pound. Like really pound. It’s incredible the sound that comes from one little amp. It’s tiny.Worth every penny.

    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
