Power Specifications - Full Range Channels

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 speakers or subwoofers 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.

100 watts x 4 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 speakers or subwoofers 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.

150 watts x 4 channels
Bridged RMS Power

Bridging refers to combining two channels on an amplifier to create one channel with double the voltage and an increased power output. A 2-channel amplifier will bridge down to 1-channel and a 4-channel amplifier can bridge to create 2-channels. An amplifier is most commonly bridged to drive a subwoofer.

Remember, once you bridge two channels down to one its final impedance will be 4 ohms unless otherwise specified. This rating lists the RMS power created once an amplifier is bridged.

300 watts x 2 channels

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.
4
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.

600 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.
4 ohms
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.
No
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.
No
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)
High-pass (HP)
High-Pass Crossover Frequency
The high-pass crossover frequency can be a fixed crossover point or a variable crossover range. A variable high-pass crossover allows you to select a specific crossover point which allows frequencies above the set crossover point to pass, while making frequencies below 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
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.
90 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.
No
Fan Cooled
A great feature to have if an amp generates a large amount of heat. Cooling fans can help regulate the temperature to prevent the amp from overheating (burning).
No
Fuse Rating
The amperage and the number of fuse(s) an amp requires.
60A X 1 In-Line Fuse Recommended
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
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.

Clean Class D on Highs - VALUE

July 25, 2014

I have been a Rockford fan all my life. They represent QUALITY and set standards. I am proud owner of power and punch series amps. Now I have prime to cover all the lines. This amp, being a class D for one, on highs, is not the same as AB but I can tell you that you REALLY NEED TO KNOW YOUR SOUND to tell a difference. 99% probably wont. There is a difference when it comes to comparing prime to punch and to power. If you don't own a power series then you won't understand. But when you do it's obvious you have something special. Prime is great, having this r600.4 on RE XXX 6.5 components up front and Infinity Reference in the rear, you get plenty of power and a clean signal. If you are tight on your budget and want VALUE matched with quality then this is a great choice.

Best amp I've owned

February 15, 2013

Big brother to my R400, I have the R600 powering 2x8 inch bazooka tubbies, and 2x10 inch bazooka marine tube subs. Incredible depth, clarity, and volume. Factory tested at 820 Watts RMS. I cant imagine how loud this would be in a car - it fills my 39 foot boat with sound.

A year powering my setups, great amp!

August 21, 2013

This amp is a dream! Well worth the price. It's reliable, clean and efficient. For my first setup I used it to power polk db's (2 components in the front and 2 coaxials in the back. Those speakers were monsters. I upgraded a few months later to polk's high end MM series. I only installed two front components for my sound stage and I'll tell you, I push it to the max all the time and still receive VIVID clarity, sound quality, and power from the combo of amp and speakers. This amp is versatile! So if you decide to switch it up like I did, as long as you do your research (and your math) this amp is unbeatable.

Power house for an entry level amplifier

June 8, 2012

Do not underestimate this amplifier just because it's Rockford Fosgate's entry level Prime series. This little guy packs solid lows and clean highs that will scream through your Mids and Highs. I have this amplifier running full range speaker configurations but I'm sure it would run moderate subwoofers fairly easy. All in all if you're in the market for a solid 4-channel amplifier I would highly recommend this product!

Save Your $$ and Buy this Amp!!

July 22, 2014

On strong recommendation from another seller for a less than $200 amp I bought Zapco 4channel 75/channel amp, and in less than one year started having problems. I bought this amp from Sonic a month ago and I wish I had saved my $$ and gotten the R600 instead. Its a noticable step up in power, particularly running at 2 Ohms/150/channel with my Image Dynamic CTX compontents and ID8 sub. Like the rest of the reviews, I have much bigger, clearer SQ, soundstage separation and especially midrange sound coming from more power.

Clean - Nuff Said

September 27, 2014

All I can say is wow... just wow. Clean sound, compact design, and even when, like the other Class D amps, ran hard barely breaks a sweat. Although it might be paired wrong with some speakers I've never heard of they still pack a punch for uncommon. Either way this amp does pack some punch, love it.

I've never heard rockford amps before but now I understand the hype. I will buy rockford again and recommend to everyone. And in the picture it looks small but it's pretty thick to be honest. But still compact.

I was in the market for a new 4 channel, this is what I needed. Rockford has a solid reputation from its early days when I used an old school power 650 to power some SPP154's ( old power 15's ) back in the early 90's. Rockford has never failed me.

Convenience of website in searching for amplifier, specifically how you can filter the amp by the RMS power output. Also I wanted to purchase from a trusted source so there would be no issues with shipping, product accuracy, etc.

gain setting for rockford fosgate amp ?
A shopper on Jan 11, 2015
Best Answer: Hello,

Unfortunately, we could not reach your question in time. If we had, we would not have allowed the system to submit it. You are going to continually receive vague/general responses, because your question is rather open.
Assuming you are asking 'What the correct Gain setting is?' then the answer is 'There isn't one'. If there was a "correct" setting, the amp would come stock with that setting, and not allow you to adjust it. The Gain/Level/Sensitivity is intended to match the output of your headunit. So if you headunit puts out 4v, then you will likely fall around 4. Nevertheless, we suggest doing your own homework on "How to properly set the gain on an amp" or taking the amp to a Professional . A professional will use proper equipment, like the SMD DD-1 , to accurately set the Gain.

SMD DD-1

Does the punch eq only operate on low frequency and only on the rear channel when in 4 channel mode? Or does the crossover settings (such has set to HP) change it to a high frequency like on the Punch series amps?
Tripp P on Jun 24, 2015
Best Answer: The eq is a +18db @45hz bass boost. It will only adjust your low end frequencies, so I suggest not using it. It also makes the speakers distort easier. And it will adjust all channels that are in operation. Changing the crossover setting will not adjust the frequency nor the db level of the punch eq.
