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.

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
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
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 - 12 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 
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.

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.

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.

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.

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!

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.

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.

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.

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.

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 .

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.

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. )

Hector O on Nov 2, 2014
Rockford amps have always been solid, for the price you can't beat 500W RMS @ 4 ohms
Fred G on Sep 4, 2014
could this amp power 1 10 inch p3 at 2 ohms healthy? this amp does 500 rms and the sub is 500 rms 1000 watt max will it be healthy for the subwoofer?
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.

I sold the car that this amp was in and forgot to get the remote. I want to install this in the car that I have now. Will the amp still work without the remote?

Best Answer: Hello Kirk,

Absolutely; you just will not be able to adjust the Gain/Level 'on the fly'. You can regain that feature by picking up a Universal Remote Level Control like the NVX XBRC;

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 .

I have a 1968 C-10 Truck and are running a custom autosound with 300 Watts Peak featuring 2 Channel RCA Auxiliary Input for Satellite etc, 4 Channel RCA Pre-outs and Subwoofer Line out w/Level and x-over Adjustments with (2) 6in Pioneer Speaker 120 watt speakers, w/ (2) 200 watt 8" woofer and 2 Piezo tweeters and a 40 watt Dash Mount Speaker. Also, i'm running (2) 10" sub woofers, What amp would you recommend or would i run multiple ones. I've seen a lot of people recommending the Rocksford Fosgate Punch 300 series with this radio. Can you help?

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! Hope this helps. Birth sheet on amp was 678 watts if I remember right, plus it's really small which is awesome
