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.

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.

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.

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
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)
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.
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 - 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
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.

Great Amp, Great Price, Delivered Fast

January 29, 2015

Title says it all. Have ordered quite a bit from Sonic in the last few months and absolutely everything has been perfect, no snafus at all. Even the wiring harnesses and face plate adapters THAT WERE GIVEN FOR FREE AND OFFERED AS A SUGGESTION at the time of purchase were perfect. My installer said it was one of only a handful of times in his 15 yrs of stereo work that someone brought ABSOLUTELY EVERYTHING that was necessary to complete the install. Sonic made me look good!

Great Sound, Bad Thermal Management

January 22, 2015

This amp really sounds great, running 4 RF component systems and a kicker CVR 12 in a sealed box, the electronic crossovers are fantastic and the amp has plenty of power to reenforce the bass and the treble frequencies. the only problem is that this amp can get hot, on a warm day in a black car the amp will thermally protect and require several minutes to cool off, my recommendation would be to mount it with lots of room for airflow or you may have problems driving 5ch at full volume. 3 star durability for the heating issue.

Tried others, kept this one

February 23, 2014

This amp does the job well. I tried to save a few dollars with another brand and sorry I just didn't go for the Rockford in the first place. Its not a show amp that you'll brag about looks, but the music is nice and clear. I'm pleased with power of the sub channel and the remote control is a great feature to adjust the punch depending on your mood. Its great to have all the tuning options but it took some effort to get it dialed in just perfect along with the tuning settings on the deck. I'm only running one sub but think of adding a second now that know what the amp can deliver. Overall, a great product for the daily driver.

Awesome 5 Channel Amp

October 11, 2013

I would definitely recommend this amplifier, this thing is a beast! This amp is running a pair of Pioneer TS-D6902R in the back, a pair of Pioneer TS-D1602R in front and a AudioPipe Subwoofer. Well this amp pushes them very clean, very smooth and VERY loud. I have no complaints. For me this amp is a must buy, and for the price, why not?

Why did you choose this?
Sonic Electronix Store
The price, and I had an older 300-1 punch mono amp for years with no problems so I settled with the prime 5 channel amp as it has a price point I'm comfortable with. My sub is only rated for around 300 RMS, and the 50 watts per channel is enough for me - I just want nice clear sound.

Does this amplifier feature auto-on when an audio signal is detected or is a 12v remote line required?
A shopper on Nov 27, 2014
Best Answer: Hello,

The R600X5 does not have "Sensitivity On", and will require a 12v Remote Source. If your vehicle/project does not provide a suitable 12v (delayed) remote/accessory source, then you are able to rig a module - like the PAC TR-7 - to provide you such a source.

Which amplifier has more power? The Hifonics ZRX 1000.4 or the Rockford Fosgate 600X5?
A shopper on Nov 30, 2014
Best Answer: Hello,

I'm sure you already know; but I need to point out that you are comparing a 5ch vs a 4ch. Of which, a 4ch will often have More power to its Full Range channels vs a 5ch. This is the case here. The Hifonics ZRX1000.4 is likely providing ~60w RMS x 4 @4ohms vs The Rockford Fosgate R600X5 50w RMS x 4 @4ohms & ~100w RMS x 4 @2ohms vs 75w RMS x 4 @2ohms. The fifth channel on the Rockford Fosgate is obviously a moot point, due to the ZRX not having one.
