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.

50 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.

75 watts x 4 channels
RMS Power @ 1 ohm

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 1 ohm, 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.

Not Stable
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.

150 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.
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.

AB / 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.
5
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.
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.
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)
Full (AP)
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.

80 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 - 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.
Optional (Accessory required and sold separately)
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.
40A x 2 
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.
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.

Very Nice Amp!

October 7, 2011

I bought this amp, so that I could power all my speakers and sub, with one amplifier. I have a toyota tundra standard cab. Even though I do have a decent amount of room behind the seats, I wanted the install to be clean and as compact as possible. Having ONE amp, was what I was aiming for.

This amp is not huge by any means, but it does the job nicely. Like all RF amps, this one comes with a certificate on certified power. Listed as 600 watts rms by 5 channel at 2 ohms on the box, mine is rated at 721 watts rms by 5 channel at 2 ohms of actual power on the certificate.... Which means the sub is getting about 360 watts rms since it is 2 ohms. Half of the power goes to the subwoofer and the other have is spread out among the rear and front lefts and rights. So each output for the speakers is getting about 90 watts rms at 2 ohms. I have infinity speakers, and infinity makes their speakers all 2 ohm independent. So they are getting what they need.

Very good signal to noise ratio and very clear sound. VERY LOUD!!! I have the inside speakers' gains only about 1/3 the way up, as it hurts my ears to have them any higher. I barely have to turn up the HU. The sub is being powered very well and hits hard. I was deciding on this amp or one of the kicker 5 channel amps, but I went with this because of the price, and I knew it would be rated much higher than 600 watts rms, and I was correct... Good Purchase. I highly recommend.

Great Amp for the money

December 7, 2012

I have this amp running all 4 component polk db series speakers and 1 massive (brand name) 12" sub in a ported box. I have a 4 guage power wire, and monster 6 channel RCA's on a Keenwood deck with 4 volt preamp rca outs for front, rear, and sub. With this setup i am only running the amp at half power and without hyp or exageration this amp suprised the heck out of me. It friggen rocks like a multi amp setup. So for the price, you simply can NOT beat this amplifier. For a moderate setup and a great music experience this is the amp for you. And you can always trust Fosgate.

Great amp for the money!!

September 9, 2012

I have had multi-amp setups in the past and wanted to try out a multi-channel amp. Based on my preferences I like the multi-channel better. This amp puts out plenty of clean power when tuned right. I would definitely recommend this amp. Sonic had it at a great price and I received my shipment a day early.

Love it!

July 17, 2012

I did a lot of research before selecting this amp and am totally satisfied with it. I have owned it now for over 6 months. The certification enclosed with it stated the output was 751 Watts! I use it to drive two Boston Acoustics 6x9s in the front doors, and two Polk 5.5 coaxials in the rear plus two Polk tweeters in the sail panels and two Polk 3.5" speakers in the dash. It also drives a 10" Pioneer sub under the rear seat. The amp is mounted behind the rear seat of my 2011 Tundra DC.

The sound is crystal clear and I have more bass than I need so I usually keep it at 1/4 and rarely more than 1/2 of the full limit.

You can't beat this amp for the money!

March 7, 2012

This is a very nice amp for the money. My amp arrived with a birth sheet of 700 Watts RMS total power. The amp provides lots of clean power and it is very easy to tune or make adjustments. They even include a separate bass control wired remote (Kicker charges you $25 extra for theirs). Overall a solid amp, from a top manufacturer, that features quality construction and ample power.

All in one power

February 10, 2012

Looking for power for all of your speakers and don't want to spend tons or have several amps, this amp is the ticket. About 1/3 power is all I can stand in my vehicle. I liked having one amp to drive 4 sets of speakers and one sub. I will probably look at another R600-5 for one of my other cars. One critical thing to mention, you must use 6 RCA connectors, 3 pairs, if you want 5 speaker setup. I used 4 with a y-spliter for sub inputs. There is no switch to combine inputs for using a single RCA. I would include the cost of RCAs in your budget.

Overall nice amp, a bit bulky for concealment

November 19, 2011

I bought this amp for my 2008 dodge ram truck. My first thought was to conceal this under a seat because I wanted a stealth system. It really was alot longer than i first thought, but once I got over the length this was exactly what I wanted. Im using it for my surrounds running an alpine type R system 6.5 and 6x9. overall this thing is sweet, with no heating issues and lots of power.
