Power Specifications - Subwoofer Channel

RMS Power @ 4 ohms
The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far. If the final impedance of your speaker(s) or subwoofer(s) equals 4 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound. The 5th channel on these particular amplifiers are usually dedicated for driving subwoofers.
300 watts x 1 channels
RMS Power @ 2 ohms
The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far. If the final impedance of your speaker(s) or subwoofer(s) equals 2 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound. The 5th channel on these particular amplifiers are usually dedicated for driving subwoofers.

Amplifier Specifications

Amplifier Series
This designates the series of the amplifier. Many amps are available in a litany of different wattage and channel configurations, but maintain consistent features throughout the product line.
Prime (Rockford Fosgate)
Amplifier Class

An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.

D
Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
1 - Mono
Total RMS Power Output
Total RMS power is measured by multiplying RMS power per channel by the number of channels, and is calculated at the lowest level of operating impedance.

RMS power is the amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.

The RMS output figure is much more accurate than the peak rating when comparing products.

500 watts
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
4 AWG
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
2 ohms
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
Not Bridgeable
THD at Rated RMS Power
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
<1.0%
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Yes
Preamp Outputs
Many amplifiers are equipped with RCA preamp outputs which pass the original music signal from the source to additional amplifiers. This is known as daisy chaining because the source connects to the first amp, and the first amp connects to the second amp, etc. The advantage to daisy chaining is you only need one 2-channel RCA cable to transfer the signal from the head-unit to the amplifier, and then one additional cable for each amp being daisy chained.
1 pair
Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

Low-Pass (LP)
Low-Pass Crossover Frequency
The low-pass crossover frequency is typically used for subwoofers. It can be a fixed crossover point or a variable crossover range. A variable low-pass crossover allows you to select a specific crossover point which allows frequencies below the set crossover point to pass, while making frequencies above the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

50 - 250 Hz
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
>100 dB
Bass Boost
The objective of the bass boost is to get more kick out of your subwoofer. It is a circuit that emphasizes the lower frequencies at a given point. The bass boost should always be set first before setting the gain. This feature is known for destroying subwoofers and is commonly used incorrectly, so be cautious.
0 - 18 dB
Bass/Gain Remote
If the amp comes with a bass/gain remote you will be able to control the level of your bass from your dashboard. Typically bass remotes also include a 16-20 ft. wire for installation.
Yes
Fuse Rating
The amperage and the number of fuse(s) an amp requires.
50A X 1 In-Line Fuse Recommended
Strappable
Some amplifiers can be "strapped" together in order to increase the output of a single audio channel. These amplifiers feature RCA preamp outputs, allowing you to pass the signal directly from one amp to the other to ensure consistency.
No
CEA-2006 Compliant
Amplifiers that have been tested to meet specific standards. When a car amplifier meets these standards, you can be sure that it will be able to produce the amount of power specified by the official CEA-2006 rating. Usually, these rating consist of the following items:
  • RMS Power
  • Signal-to-Noise Ratio

This rating applies to both external car amplifiers, as well as the amplifiers inside of in-dash stereos.

Yes
Sonic Certified Amplifier
Sonic Certified amplifiers have been tested by the experts at Sonic Electronix to meet or exceed the wattage ratings provided by the manufacturer. If this is marked as Yes, then you can trust the wattage ratings. If marked as No, then we have tested the amplifier and it did not meet the advertised wattage ratings. If marked as Not Tested, then the Sonic Electronix experts have not yet been able to test the amp.
Not Tested
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.

Happy and impressed.

December 27, 2013

An absolute steal for the price. I have this amp wired to 2 ohms at 500rms on a fosgate punch p2d4 10" and it punches alright. I only have the gain set at half way. At first I had it installed to a stock stereo, what a waste. Now I'm running a pioneer 3500bhs and it has phenomenal sound, punch, clarity and rumble. It has more than enough power. Very happy and Sonic matches prices for less.
Will always shop here in the future.

Rockford Fosgate has great power!

January 9, 2014

I bought this amp to upgrade from a 300 watt RMS Kicker amp. I enjoyed the Kicker amp, it could shred, and reliably too. However, this review isn't about the Kicker amp, it's about the Rockford Fosgate R500X1D. I installed the Fosgate and powered a 12 inch Polk, which burned it up. Then powered a Alpine 12 inch, which it nearly burned it up. This amp can REALLY push power! When you pair it, DO NOT just wing it, do not just turn the volume up to 3/4 and turn the gain up to 1/2. Any distortion pushed from this amp will kill a subwoofer. Meter it and O'scope it (or DD1 it). But when you set this baby up right, this amp ROCKS! I have it set up with 2 Kicker 12 inch Subs in a premade Kicker enclosure, and it kicks! I would definitely recommend this amp.

Decent amp for the price.I thought i enjoyed this amp,until i heard my sub through a different amp. I am changing out all my stuff for JBL (just because. no real reason...at first)when i hooked my 12 inch P3 to the JBL amp it was clearly a cleaner sounding bass note! For the money a good amp. If you have a little extra coin go for a different option.

Install went nice, when I first installed it it was on an old Sony Xplod 1200W sub, which at 4 ohms isn't bad, but when I put it on my twin Kenwood 3013PS 12" 400W RMS subs... it punches and punches and it's not even maxing out the subs themselves. I'm impressed on the power output, the birth sheet stated 664W RMS from the factory at 14.4V. Over all, well worth the purchase.

This is my first amp, so I have only second hand prior knowledge, but it drives my RF 10" sub really well. It was super easy to install and the class D doesn't get very hot at all so mounting options abound. All in all I highly recommend this amp if you're looking for an affordable way to drive a sub. It won't rattle the neighborhood, but it does get a few looks at the stoplights!

(I don't know about the durability, I'm sure it's fine, but it's new so I can't can't comment on that one. )

Great budget amp

December 21, 2014

I already own a 500.1bd and 700.1bd RF punch amps for my two cars. I wanted another for my wife's vehicle. Forgot to mention we had a RF 300.1 in hers. I recently bought a Alpine sws 12d4 for her to replace an old kicker first gen crv. This is a single sub in a prefab ported box. Just wasn't happy with the 300.1 anymore, not enough power.I read the reviews on the 500x1d and was hopeful that it would be a good fit for her alpine without spending 200+. Got the amp Saturday and installed it. I have to say that it looked even better than the pictures. Also that it is small but heavy. Cool. Plenty of power with the sub wired to 2ohms. I only have the gain set at half. I'm sure we will have this set up for a long time. It bumps now and sounds great. Since I have only had the amp a couple days I'm giving durability 4 stars.

just hooked up this amp to two p2d2 8'' subs from Rockford, which contrast it nicely. when i first pulled it out of the box i was surprised on how small the thing was! which is great for small vehicles, in my case a 94 Nissan hard body. would recommend this sub to any one that ones a quality product at a low cost.

Extremely happy and impressed with Rockford's power

September 24, 2014

At first, I was skeptical about buying this amp due to the fact that I had never seen or heard a rockford amp in person before. But after I installed the amplifier with ease, I was astonished at how well this amp drove my subwoofers. I have it powering 1 Rockford P3D4-10 and it bumps. I have this amp and sub side by side with a second P3D4-10 powered by a Kenwood 7005ps 5 channel amp and when the sub powered by the ken wood amp starts to distort, the sub powered by the rockford amp stays strong without the gain turned up all the way. Extremly impressed with this amps capabilities and power and very happy with the sound. The pass-thru RCA ports on the amp are a bonus as well. I would definitely recommend this!

Solid amp for a great price

May 11, 2014

I have this running the newest P3 15 at 2 ohms and does it's power then some. Awesome budget pair up, the subs seeing 3 cu^ft at 35 hz in a L port design box. Loud and clean, this amp beats the crap out of that P3 15. The birthsheet said 637 rms. Originally I've always ran punch amps and honestly I thought that I downgraded because of budget purposes. But I sure was wrong. It sounds great, it gets lukewarm at the most after about an hour play time at full tilt. It was kinda difficult to get 4 gauge wire to fit but it fit barely on a Rockford 4 gauge kit. I guess that's the only complaint but besides that this amp is absolutely awesome. Especially for what you give for it. You'll notice when you open up the box, this amp is tiny! But made of a high quality construction, it's solid. Everything is oscoped, perfectly clean and dialed in. I highly recommend this amp for the value and performance. If your planning on having a 600 rms setup, go for this amp. It's cheap, reliable, and exceeds it's rating. I've had it for 1 1/2 months, and it's had a lot of play time full tilt for extended periods of time. Highly recommend it.

Not a whole lot to say here. Excellent product thats is very well made (typical for Rockford). CEA compliant and VERY compact which is probably my favorite part. LOTS of clean power for the size it is, it came with a certificate of 629 RMS. Runs pretty cool. It gets warm but never burning hot although I am just powering 1 MB Quart PWM304 with it . Highly Recommend this product. The only con are the angled wire terminals.

Lots of Power for the Price!

May 13, 2014

I purchased this amp and have had it in my 2005 Impala for 1 month now. It is powering 2 12" MTX Terminators, and it slams! Although the specs online say the amp is rated for 500 Watts RMS, my amp came with a spec sheet stating that the amp was tested and provided 642 watts of clean power at 2 ohms. For the price, it is one of the best amps available.

The amp was very easy to setup. The only issue I had was when I was trying to fit the 4 gauge power and ground wire into the terminal block on the amp. I managed to get it to fit, but the terminal blocks are angled down. Due to this, it is difficult to get the wires to fit once the amp is mounted to the sub box. This is a minor complaint, because once the amp is connected, it is easy to tune and it works great.

Also, the included dial works very well, and is useful when you simply want less bass without having to adjust the gain dial on the amp.

Overall, this amp works very well. I have not found anything better for the price. It provides much more power than it is rated for, never gets warm, and is built very well. Personally, I highly recommend it.

March 11, 2014

This is a reputable brand that is known for there high quality products. So I bought it. Paired it with a jl w3v3 10" and it sounds awesome! I would definitely buy another Rockford amp. Just make sure it fits well with the wattage of your sub and you're golden!

Stage 2 for Stage 1+ prices!

January 30, 2014

This Rockford Fosgate R500X1D is an amazing piece of hardware! I had a previous gen (R500-1, which was 2 previous gens behind) that was a Class A/B amp and the birth sheet was around 524RMS @2Ohms. That amp was OKAY until it started to over heat even when set with a DMM below the correct gains. This amp is literally half the size (just bigger than a CD case) and is the more efficient Class D which allows for better input-to-output power. This 500w amp was birthed at 638RMS @2Ohms and let me tell you...that's no joke for SPL!

I have a Pioneer TS-W1200PRO (12" DVC 450RMS handling) in an AE sealed box @1.08cu/ft is loud! I have this amp DMM tuned to about 475RMS after I broke in the sub and it's enough to feel the air moving with 3/10th bass boost. I can't be more pleased with this little thing, at least until I get my next sub that can handle the power (google SoundQubed). I've ran this amp at full (tuned) levels for a trip starting in NC and ending in upstate NY (10 hours) and not once clipped/got hot.

Pros: Definitely underrated power specs, very small and can fit in most any corner, Control knob comes in handy when a 5-0 pulls up at a light with the windows down, uses allen wrenches for wires (and comes with them), Stays very cool.

Cons: No subsonic filter (thus 4 stars), the remote has a VERY bright blue LED and can be bothersome at night...but I'm going to tint it or mod it to control another LED circuit to flash with the beat in the hatch.

I recomend this amp to any one its looking for a budget amp..for the price.!! ROCKFORD FOSGATE ALL THE WAY.!!

For it's size, this amp pack a prime punch! I run a pair of 12's off this in 2 ohms. The bass hits hard, shakes my mirror, and allows quarters to be bounced off my trunk. While you won't be breaking any windows with this, it has set off some car alarms in parking lots.

I put this amp onto a pair of Pioneer TS-W254R subs and build a custom box. I installed this amp in my 16 yr old sons car. This setup really hits hard and you can imagine how he plays it. Its been installed for about 2 months and have not had one minute of trouble. The amp plays well and runs really cool even when really pushed.

This amp rocks. I got this same amp and an earthquake sound 10 inch sub a week ago and it hits hard for a 10. This amp is really cheap but still great quality. Might even hook my friend up with one. I have it's big brother the 1200d pushing two kicker 15s hard. They are hitting around 140db. Great amp both of them.

March 15, 2015

I own this little amp and matched along with 1 RF P3D410 500 RMS / 1K Peak woofer in a ported box. Brand new, it sounded legit for the budget but after the break in period was over it didn't perform as it once was expected. Sure it hits but there's something that feels off. I have it wired properly for sure and the power is being supplied by a Optima Yellow Top battery along with a 160a alternator but it's just not hitting as hard. Maybe it's the ported sub box I bought from Amazon. Don't know but I'm going to try a sealed box to see if makes a difference.

Super power in a small package

March 5, 2014

I have this amp powering a single Rockford Fosgate P3D4-12, this amp will put some amplifiers twice it's size to shame. All i can say is pure undistorted vibrate your azz power. Way underated i cant turn the gain half way because something will give either my back glass or my front no BS, whoever doesn't believe me come sit in my 07 accord. For now i have the sub in a prefab sealed box, but will soon get a custom built to specs ported enclosure. Love Sonic, love their service, and prices will be ordering much more soon, thanks.

Bomb Proof Amp

October 17, 2014

I wasn't going to review this amp, but I just feel like it deserves some recognition. I'm buying a NVX JAD1200.1 to replace this Rockford, so I decided to smoke test my R500X1D. I wired this amp down to 1 ohm on 2 Sound Stream T7 10's. I just went on a 30 minute ride blasting Decaf through it at max volume (probably clipping a little). The amp didn't even get warm! Never went into protect mode. Subs didn't get warm. No hiccups. Bottom line: Rockford makes awesome amps.

I'm sure they don't recommend wiring this little guy down to 1 ohm, but it's probably over 3 ohms at all frequencies after box rise anyway. The amp has never given me any problems. It's very solid and feels well built. Even on really hot days in Florida I don't feel bad about blasting away for hours on end. It's not anything crazy, but it does bang pretty nicely for an amp rated at 500 watts.

I wish amplifier manufacturers wouldn't make us use a screwdriver to set the controls. Why can't they make it so you can adjust it by hand like the volume control on your radio? It would stop the gain setting etc. from getting scratched up and you could probably set it more accurately by hand. Other than that, it's a solid amp.

Never gets hot....

November 13, 2015

Seriously. This is the first RF amp I've owned and probly the first good class d amp I've ever owned either. I've heard if you run this at 2 ohms it will get warm but me railing on the sub at 4 ohms doesn't even get this thing heated. In fact it always feels cold to the touch. It was worth the minimal amount of extra money to get a good brand amp for this alone as it gives many mounting location options, not to mention longevity.

Cons: amp has no fuse. It's up to you to be SURE to correctly fuse this thing with the amp kit, not really a con an fyi.
The remote bass controller light is blazing bright, not sure how someone could drive with it facing you. I took it apart and taped over the light and it's still bright enough to see when on, definetly liveable now.
I wish manufactures would incorporate a a power switch into the remote bass controllers. Like if you turned the switch all the way down it would click at the end and turn the sub off. Seems like a no brainer as I sometimes take the sub out of the vehicle and I don't want the amp to even turn on.

Overall? Can't beat it.

An absolute steal!

May 6, 2016

I bought this amplifier a few months ago on sale for around $120, and I am blown away at the amount of performance it delivers.

Although it is rated 500 watts RMS @ 2ohms, these amps actually put out well over 600 watts as many other owners will say. My "birth sheet" that came with the amp showed that it had been tested at the factory to put out 624 watts RMS, while some other units have tested at 630-640. What's crazy is just how small this little amp is. It easily fits under the driver's seat in my Corolla, along with a 2 farad capacitor.

I have used it to power a cheap Kicker Comp at 4 ohms, and now I have it running a single 600w Pioneer TS-3003D4 at 2 ohms, which it does with no problem. This amp hardly ever gets hot, and has never shut off on me. This is the first Rockford Fosgate product, I have ever bought and so far, it has been great!

One thing to note though, is that there are no on-board fuses, so make sure you have an inline fuse ( I'd recommend and 80amp) wired on your amp's positive power cable (which you should have regardless. )

One Awesome AMP

May 1, 2016

I have been a long-time fan of Rockford Fosgate, all the way back to my High School days in the 90's when I was proud of my punch 45.
So, when I decided to add some bass to my 02 Dodge Ram Quad Cab 4x4 I first looked at RF. I didn’t want to just settle on RF simply because I loved their products and quality over 20 years ago. After all the playing field has been greatly leveled since that time and RF has out sourced their entry level "Prime" Series like many others have.
So, for several weeks I researched the different brands of amps, reading countless reviews and watching YouTube videos. I kept coming back to this RF Prime R500X1D. The price is amazing for what you are getting. The best part was that It would be a perfect power match once driven down to 2ohms for what I was intending to install.
I obviously purchased it, which is why I am writing this review.
I have zero complaints about this amp. RF is known for under rating the RMS on their amps which is impressive to me in a world where 200 watt amps are regularly sold as 1,000 watts. The birth sheet that came with my amp was approx 637 watts RMS. Thats not bad when I paid for a 500 watt RMS amp.
I am VERY impressed!!!!
My Only Regrets with purchasing this amp is I "kinda" wish I had gone ahead and purchased the R1200-1D. Then again the average amp draw for the R500X1D is only 25amps while the R1200-1D is 55Amps.
And… right now this amp has pushed my two JL audio 10’s like a beast and it barely gets warm.
I can say that It doesnt effect my factory electrical system and I haven’t had to modify anything.

Cons:
The only complaint I have about this amp… well not necessarily the amp but the “Punch Level Control Knob” is that the blue light is reaaallly bright. Normally I like the accessory lights in the interior of my truck to be bright but this thing is a little annoying to me. One of the biggest reasons I don’t care for it is that it’s so bright that you can’t tell what the actual level is sitting at (at night) because the light prevents you from seeing the position of the knob face. I’m considering just putting a small piece of scotch tape over it. This is def not a deal breaker but is worth mentioning.
Also, it would have been great to receive the typical RF security screws that they include with so many of their products.
One last thing… the angle of the power and ground block makes for a fairly clean install, especially when the wires are run from under the amp and then into the block but can be a pain to get 4awg wire completely into the hole at that angle. I ended up installing the power and ground wire into the amp and then mounting the amp to the cab floor under the drivers seat.

To bad we can’t post pics of our installs on with our reviews.

All in all, I would def recommend this amp to anyone that is looking for excellent power, clean sound and an incredible price.

My ears will never be the same

March 10, 2016

This thing, this tiny little black and grey box of metal, seriously blew my mind, and quite possibly my ear drums after installation. I don't know how nor did I expect it to pack as much of a demonic punch as it does. I have it in the back of my Hyundai suv, pushing 2x Rockford fosgate 12" p2's in their own custom vented box. I've never been known to scream like a 12 year old girl at a princess party, but the first time the beat dropped after I put the thing in, that shrill little noise could've been hear for miles I'm sure. It hits so hard it will literally blow a lighter out, that a person in the front seats is holding. It has extended the cracks in my front window ten fold, ruined a decent amount of my hearing I'm certain, dropped sunglasses out of the ceiling without notice, and hasn't stopped moving my rear view mirror to where I can only see a little bit of the backseat floor area. But I love it. The best little investment, for the money, that can possibly be out there. A true 500w amp, an essential for anybody seeking that life ruining level of sound. (Listen at your own risk!)

March 6, 2016

I bought this amplifier to go with my single Rockford Fosgate P3 12 inch subwoofer. The sub can handle 600 watts rms, 1200 watts max, and the birth sheet of my amp claimed that the amp can put out a very powerful 631 watts rms. At 2/3 gain and 1/2 punch EQ level, the subwoofer, which is in a 1.8 cu ft ported box tuned to 36 Hz, is clean, loud, and probably going to result in permanent nerve damage (which is why I will not turn it up much further: PLENTY of bass).

One drawback, however, is the lack of an adjustable subsonic filter. Although, I have heard from many sources that this amplifier actually comes with a fixed subsonic filter possibly around 30 Hz. This is evident, at least in my setup, because the subwoofer is obviously not trying too hard (little movement) on freqeuncies below 30 Hz, which makes me feel comfortable having it in a ported box. I do not believe that it has a chance of bottoming out with my current amplifier settings.

Rockford Fosgate (awesome)

March 5, 2016

This amp is the first from Fosgate for me. This amp is awesome. It's small but puts out a lot. It's a single channel amplifier mainly for pushing subs. I have 2 10inch kicker comps hooked up to it and they sound amazing. The amp doesn't get that hot and so far I have yet to see any cons on this amp. The awesome people at sonic electronix helped me pick this one out as I am a beginner and I don't think they could have recommended a better amp.

Excellent budget amp

February 27, 2016

This amp replaced my aged JL Audio 500 watt amp. I was on a budget so I chose the Rockford Fosgate Prime amp for RFs reputation, the price, and the positive reviews. It effortlessly powers my single JL Audio 10W6v2 and it sounds great to me. It did take a few days to break in and sounded a little flat at first. But after 5-6 commutes, it fattened up and started modulating my heartbeat. Cheers to Sonic Electronix for great customer service.

GREAT PRODUCT!

February 24, 2016

Ive always been a Rockford fan. Previously I owned the 1000 Watt prime monoblock but ended up selling it with my previous system. At first I was wanting more power when shopping but settled with this 500 Watt because I know rockford pushes true RMS to watts. Coupled with tthe Rockford Fosgate P3 12'' this thing pushes. Sounds great, clean audio and worth every penny. Would recommend to any one interested.

Its a Rockford enough said

February 22, 2016

I bought this amp because of its size and power out put also great price. Overall better than I expected but again it is a Rockford. Only negative for me the remote is useless it sounds better without it hooked up. Not really a big deal as I don't mind retuning once in a while. I've been using Rockford Fosgate amps for 15 years im happy the Chinese production hasn't ruined them I will absolutely continue buying their brand and continue recommending them to all who ask

Really Impressed.

February 19, 2016

If your looking for clear non stop power in a small package look no farther than the 500.1 Prime , this amp is a little war horse and I mean that, my birth sheet said 637 watts And I bieve it, I'm currently pushing 2 Kicker Comp 12 wired at 2ohm and it literally shakes my full size Crown Vic to pieces. And might I say I'm more impressed with how small the amp is my last amp was a Dual 580 and that was like a foot+ long , If your tight on space and money and want a amp with serious power look no farther than the 500.1 .. I'm sticking with Rockford Amps , I'm Pushing 500+ watts [email protected] and my Kickers are thumping like crazy ....

Thanks Rockford For making an incredible amp with amazing clear power in a small amp ...

Rockford R500X1D Amp

January 29, 2016

This amp is a BEAST. When I got it the birth sheet rated it at just under 640 watts RMS. I paired it with a rockford p2d4 12" sub and it hits HARD. Very easy to set up, and is nice and small so it can mount just about anywhere.

Great amp

January 11, 2016

This amp is tiny but don't let its size fool you. The birth certificate has it doing 575 watts rms; we have it hooked up to a 12 inch sub in a ported box using 4 gauge wiring. It gets super loud and boomy. The trunk had to be sound deadened because of the bass pounding.

Unbeatable price for this performance

January 10, 2016

I have this paired with a 12" Rockford sub and my system hits hard and sounds great. The amp is extremely well made and the QA sheet that comes with it has it putting out 600+ Watts into 4 Ohms. The remote gain knob is a great addition, include in the box. Easy to setup, all top notch terminals, and great controls. I am using it with speaker level inputs from my 2014 Silverado.

I do have to very small grips though. First, the plastic speaker level connector does not stay put in the amp properly. I had problems attaching and removing the connector. I had to open it up and glue it back in place, otherwise the pins in the connector were not making proper contact. Second, it has speaker level inputs but does not auto turn on/off. That to attach to my trucks OEM radio requires that you either attach it to the ignition power, which is a nightmare to get to and then pass back to amp. I choose to make my won amp turn on circuit from an IC comparitor and an RC filter. Works like a charm. It really should have had that for the speaker level inputs. Minus one star for that.

BOOMIN SOUNDS! Excellen value!!!!

November 23, 2015

Those who read this, just to let you know that I am/have been a professional electrical/IT/engineer since 1999 and this rating should help any amateurs, beginners or up to even the best professionals with purchasing this product.

This is an excellent amp, I haven't really messed with the settings to "tune" it very much I just set everything at ~mid-levels, my pioneer deck has much more options to change levels, but right out of the box, this amp has been excellent so far, has not cut out/distorted even one time since installation and use. Installation was fun and easy. (Weekend project)
I had to cut a hole through the bed lining to mount the ground cable to the chassis but it's solid grounded and it's very rugged which is driving 2 - 10" ported JBLs that have 1000 watt max power, I even dropped the Ohmage down to 2 from 4 by wiring the subs in parallel, I'm sure this helped the amp from over driving and peak current phases.

So far my system sounds, looks and feels professional and could stomp a lot of competition. Great BUY, unbelievable value!!!!
Highly recommend!

Best Answer: I would need your equipment specs (speaker RMS wattage,IMPEDENCE, model, manufacturer ) this R500xd in question is a mono amp meant only for subwoofers. If you use this for your two tens depending on final impedance of the two tens then this amp is plenty powerful for your build. If you would like further recommendations from me please ask!

A shopper on Nov 16, 2014
Best Answer: Yes peak numers really does not matter its rms that is important you want to send the same rms from the amp as sub although for the best peformance you want to give it some head room and send about 10-15% above rms to the sub . Rockford fosgate always underates there amps even the prime series so this would work very well for you set up .

i have 2 10 inch subs i got from some old home tower speakers they are both 8 ohms if i ran 2 sets of speaker wire from the amp to both of them would it harm the amp? or if i just ran one?
A shopper on Nov 12, 2014
Best Answer: The Fosgate R500X1D is rated at 300W X 1 @ 4 Ohms and 500W X 1 @ 2 Ohms. The reason it is 300W X1 and 500W X 1 is that this is a mono amp which only has one channel. With your (2) 8 ohm speakers you will be able to achieve a 4 Ohm load on the amp by taking the positive lead from each speaker and wiring them to the positive lead on the amp and by taking the negative lead from each speaker and wiring them to the negative lead on the amp. This is called parallel wiring and the formula is as follows:

Rtotal = (R1R2) / (R1+R2), so in your case (8*8) / (8+8) = 64 / 16 = 4

Do a Google search on car audio sub wiring and you should come up with all kinds of good reading.

Hope that helps.

what is the max power rating wired at 2ohms?
Michael H on Aug 24, 2014
Best Answer: Hey Michael this is Caleb N. glad I could help . This sub is rated at 500 watts rms which is continous power . Rockford amps are underated so it will push alittle more then that . A tip I would give is make sure the subs you are running are 2ohm stable also make sure to give the speakers about 10-20% over rms you want to give speakers head room when you are wanting to crank it up not the bare minimum .

Will this amp power my two 300 watt 2 ohm 12 inch kicker subwoofers?
JGrocks18 on Apr 11, 2015
Best Answer: Yes, if they are single voice coil then the amp should be pushing more than 300rms at 4 ohm. If you have the dual voice coil wired to 2 ohm then you will have plenty of head room for more. I know the power rating for this amp are underrated. Mine came with a birth sheet claiming 639 RMS at 2 ohm.

I got a kicker comp r 12" sub to go with this amp. The sub says its a 2 ohm sub, but the switch on it only has 1 or 4 ohms to select. Which setting should it be on?
A shopper on Apr 2, 2015
Best Answer: Hello,

Stephen has provided the best answer. Assuming you only have One subwoofer, then you MUST put the switch to 4ohms. Switching over to 1ohm WILL damage the amplifier. Also, the sub does NOT "say its a 2ohm sub", it likely says DUAL-2ohm. Unfortunately, you may want to consider changing out the subwoofer for the Dual-4ohm, to get the proper figures you seek. If you've purchased these products from us recently, give our sales team a call for help.

kenneth on Jan 3, 2015
Best Answer: Hello Kenneth,

For future inquiries, its important that you specify the exact model number of the subs. Your description can literally one of two current models, and one of NUMEROUS previous models. All the answers you are getting will be wrong and detrimental to your setup if you are implying any model that is not the Rockford Fosgate P2D2-8 . Please make sure you go with two Rockford Fosgate P2D2-8 . The Rockford Fosgate P2D2-8 wired in series/parallel will give you a 2ohm final load, making it a PERFECT match for the R500.

if I have 2 2ohm subs hooked to this will it give 250 watts rms to both channels??
A shopper on Dec 17, 2014
Best Answer: In short no. This is a mono block amp which means it only has one channel. If you were to connect both of your 2 ohm subs to it you would have to wire them in series which would produce a 4 ohm load at which the amp only makes 300 watts which would be 150 watts per speaker. If you wired them in parallel it would produce a 1 ohm load which will most likely mean the amp will spend the majority of the time if not all in protect mode.

Can I wire 2 Rockford Fostgate R2D2-12 (4 Ohm) subwoofers to this amp in a 2 Ohm configuration so each sub will be hitting 250 Watts?

Best Answer: This would be perfect, and will do absolutely no harm to the subs as it is split. In a system like this it is best to match your RMS rather than go above it which will not only limit your power capabilities but also over stress your amp due to running 100% all the time pending the type of music. It is easier to tune down rather than overrun everything else to meet power requirements...

Is it ok to run this amp at 8 ohms?
anthony c on Feb 20, 2016
Best Answer: Hi Anthony,

You've received contradicting information, so we're going to step in:

Yes, you can. Although there is no rating (and we can't provide one) you CAN run the amplifier at anything ABOVE its lowest stable impedance, including 8ohms.

Will i need a capacitor if i bridge this amp to two subs? They're 250 watt rms as 4 ohms
Shaun G on Dec 16, 2015
Best Answer: Hi Shaun,

This amplifier doesn't require very much power to perform well, therefore a capacitor will likely not be needed.

Also, you cannot "bridge" an amplifier to a set of subwoofers. Silly semantics, but we want to make sure you communicate with the community with the appropriate jargon. =]

I have a NEW ROCKFORD FOSGATE P3D2-12 12" 600 WATTS DUAL 2-OHM CAR SUBWOOFER Will this amp be fine or should I have gotten a 4 ohm speaker?

Best Answer: Hello Kendal,

The Dual-4ohm , wired in parallel to a 2ohm load, would be the proper match. However, Rockford Fosgate does suggest that the subwoofer can work well with 300W - which is what your driver would get, wired in Series to 4ohms - but clearly this wouldn't be the 'optimum' power .

How long is the remote bass control wire on this?
A shopper on May 5, 2015
Best Answer: Too long. Seriously, unless you're driving a limousine, I promise you'll be just fine with plenty to spare. Can't give you an actual number for it's length because I never measured. My car is a 2013 passat. Amp in the trunk, control under my dash. Still have enough wire to reach the emblem on my bumper

Is this amp https://www.sonicelectronix.com/item_67758_Rockford-Fosgate-Prime-R500X1D.html be a good match for two of these? I won't be under powering or over powering them right? Also has anyone tried these in this enclosure https://www.sonicelectronix.com/item_92143_Qpower-QBOMB12V.html or even tried the enclosure itself? Finally is this overall a good first budget setup? And if you could recommend me with a good amp wiring kit for this setup that would nice too. Sorry for all these questions as you could probably tell, I'm a audio noob. Thanks in advance.

Best Answer: The amp would have enough power if the subwoofers were a different impedance. The subwoofers are have dual 4 ohm voice coils, this can be intimidating to someone who is new to car audio. Simply put, when you connect the subs to the amp, the subs will be wired to 1 ohm (so will speak in a 1 ohm language) where that amp will put out 500 watts at 2 ohms. So what you will need is either two dual 2 ohm subs or two single 4 ohm subs. I would suggest these subs http://www.sonicelectronix.com/item_64264_Kicker-40CWD122-CompD122.html wired in 2 ohm.

If you need help with the wiring, feel free to use sonic electronix wiring diagrams http://knowledge.sonicelectronix.com/tools/subwoofer-wiring/

As far as the box goes, it's a nice box but it's a little small for you. These subs require 1.75-2.25 cubic ft per sub in a ported box and ported boxes are better when they're built specifically for a subwoofer. I would suggest this sealed box instead. http://www.sonicelectronix.com/item_33909_Atrend-12DQ.html

For a wiring kit, I suggest this one. And you can save a few bucks on it when you buy it with the rockford amp. http://www.sonicelectronix.com/item_86031_Belva-BAK42BK-Black.html

I have 2 10 inch Rockford r1s the 2015 model their stats are 200 watts rms a piece and 400 watts max so 400 watts rms and 800 watts max if I wire them to 2 ohms will 500 watts be overpowering them or will it work good?
A shopper on Mar 26, 2015
Best Answer: Hello,

Unfortunately, you won't get accurate enough information to answer your question, because you did not provide the information we need. A description of the subwoofer isn't going to help, unfortunately. You managed to omit the important part of the description, the Configuration. Assuming your drivers are Dual-2ohm , then wiring them to a 2ohm load is perfectly fine, because the amp will provide ~250w RMS to Each.

The R500X1D is not 1ohm stable so it is not compatible with the enclosure. We suggest one of the two amplifiers that is recommend on the enclosures product page. (and yes, they are "larger")

I am looking at the R500X1D does this amp get very hot @2 ohm load during long listening sessions?
A shopper on Mar 19, 2016
Best Answer: Any amplifier will get hot after long periods of play time. Your electrical is something you should keep in mind when adding amplifiers etc. This is a great amplifier, however I don't have all the information needed to answer the question fully. Need to know what subs you are using etc. Read the RMS ratings per ohm load with the amplifier and match that to the RMS of the sub/subs. I.E. 500 watts RMS on one 10 that can handle 500 watts RMS , or 2 10's that are 250 watts RMS each . This amp is capable of handling a 1 ohm load.

The Rockford Fosgate P3D2-12 is NOT a "2ohm sub" and the R500X1D is NOT a "2ohm amp" . The subwoofer is a DUAL-2ohm subwoofer and it is very important that you make that distinction. As for the amplifier, although it is Stable to as low at 2ohms that does NOT mean we call it a '2ohm amp'. As for the second part of your question, Absolutely Not! Doing so will deem the setup improper use and will void your warranty. We suggest the P3D4-12 if you want to run that amplifier.

Does the high level inputs also double as a remote turn on? I am planning on adding this amplifier to a car that has a stock head unit. Was hoping for a convenient install. Thanks
Grant on Oct 17, 2015
Best Answer: No. You will have to tag an ignition or accessory wire and run it to the amp. Make sure you fuse it online with a 5 or 10 amp fuse. Doing this adds less than 30 min and will make for a nice clean install.

I purchased this amp the other day. The problem is that it's only putting out a small amount of power. The amp before was some cheap 300w 2 channel Planet Audio mated to my 2ohm 400 rms Pioneer Premier sub. It hits good, but I wanted something a bit more punchy. Im currently running 8 gauge walmart power and ground through my car. I connected my new RF to everything and the blue light turned on. However it was putting out a very small amount of voltage. The ground and all fuses are good. My guess is that it need 4 gauge instead of 8?

*Tested with my friends system running 4 gauge, it worked great when that happened.
Travis S on Oct 12, 2015
Best Answer: Hello Travis,

There is absolutely no doubt that 8 Gauge of cheap discount wiring is not going to provide enough juice to a proper amplifier, like the R500X1D . We, and Rockford Fosgate, highly suggest investing in wiring that matches the performances of the amplifier; that is, 4 Gauge OFC wiring. However, this suggestion isn't implying that it is going to fix your problem. There are a few more variables involved, and you didn't provide enough information to touch them all. (it would be almost impossible to do so through this medium) .
Get back to us after you've upgraded your wiring, and please make sure to Then provide proper model numbers, not descriptions. For example, "2ohm 400 rms Pioneer Premier sub" can mean just about anything, and doesn't help us conclude that this is a compatible driver. In fact, if the driver is a Single-2ohm, it would Not have ran very well on a 2-Channel amplifier, but then you might mean something completely different...point is, we need a model number next time =]

Best Answer: They have similar (if not the same) specs in terms of power output.
The RF has a slightly smaller footprint (barely) than the alpine.
The RF includes a "remote punch level control" which is a knob to control the level of bass, alpine's equivalent (RUX-knob) is sold separately.
But it's always nice to have matching brands of subs and amplifiers.
The RF is cheaper too..
I have 2 MRV-M500s though and they haven't disappointed me at all.. Haven't seen the RF in action to judge

What is the true rating for the amplifier at 4 ohms? Because I know it is more than 500 at 2 ohms so I am curious on what it truly is a 4 ohms
Sadiq L on Apr 22, 2015
Best Answer: At 2 ohms the birthsheet states 517 and 4 ohm is half of that so at 4 ohm the amp would be doing 258rms watts.
