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.

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.

1200 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.
1/0 AWG
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
1 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.
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 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
Subsonic Filter
Allows you to block (filter) ultra-low frequencies that your subs cannot reproduce.
15 - 40 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
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.
100A In-Line Fuse Required
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.

lots of power for the price

February 2, 2014

My birth sheet said 1,313 watts at 1 ohm. Can't really beat that for the price. Small amp with a lot of power. I recommend upgrading your battery though. My lights dim a lot on my stock battery. It accepts 4 gauge wire but I would recommend running 1 gauge wire to the trunk then use a 1 gauge to 4 gauge distribution block so you will only have about 1 or 2 feet of 4 gauge for more juice to the amp. It does not have a built-in fuse so you need to buy a fuse holder.

No Regrets

August 20, 2014

After 6 months I'm happy with this every day. It can deliver without a problem, and the "remote punch" lets you adjust the level on the fly--couldn't live without that now. To make it happy, I upgraded my alternator and battery and added a capacitor, ran a two gauge cable to split into fours (for this and the P400), threw in ANL fuses, and now I'm happy. Real happy.

Works Amazingly

May 26, 2014

This amp blew me away. I replaced my POS kenwood kac-9105d amp with this and the difference was night and day. I've owned the amp for 6 months had have had no problems with it. It never overheats, even in the 90+ degree heat. My only complaint is hooking up the power and ground cables. 1. The power is on the right when it is traditionally on the left. I almost blew the fuses the first time I hooked it up and since the fuses are internal, I would've had a completely dead amp. My friend did this with his amp and he had to buy a whole new amp. And 2. Fosgate recommends 2-gauge power and ground cable for this amp but I can just BARELY fit my 4-gauge wire into it. It takes me forever to get the power cable in correctly. Not to mention i have the amp mounted on the back of my sub box out of sight, and the terminals are faced inward towards the box! How stupid is that? So not only is it nearly impossible to fit 4-guage wire into it, but you can't see what the hell you're doing either. And they made all their amps like this! Honestly, they could have done things better and made things a lot simpler.

learning lesson

May 18, 2014

I will say that this is a strong amp that sounds really clean but, it doesn't pair with just any sub-woofer. I have an Alpine SWR 12D2 and it is not enough power. I thought that moving up to Fosgate would be a rewarding investment and instead it was an expensive experiment. I can run the amp at more than 4-5 gain or the protection shuts if off. I have a larger sub-brand amp that can do what this RF can do, all day, and never shut off. So here is why this pairing doesn't work. (I really really wish that it was enough) Fosgate sub-woofers and most other sub-woofers are designed to function at half of the peak power is rms. (I.e. 250rms/500peak, 500rms/1,000peak. 1:2 ratio) The Alpine I use runs at 1,000rms/3,000peak (1:3 ratio). The rms is perfect matched but when the sub is finally pumping, as it is designed to, the amp isn't stable enough and immediately shuts down in protection. I'm running an XS 3400D car battery with a Tsunami 2 farad capacitor. I have OFC 1 gauge wires and everything is perfect, until I tried to change my amp to RF. I use my old amp and I guess do not fix what isn't broken. Pair this with a lower power demanding peak sub-woofer and you will like it. It is a seriously strong amp just not with my pairing.

I am nervous bout ordering stuff online! There is so many risks. When I ordered they made sure it was me ordering the product. And made sure my needs were met. I was pleased with the service as well as the product I bought from them. It was a high quality amp that was very cheap. The amp sounds great and have had no problems with it. Never once have I had a amp that I have running 2 ohms full power going to my subs and it doesn't even get warm. I am very excited I chose this amp from this website.

October 12, 2013

I have this amplifier pushing a single Alpine Type R 10D4 wired at 2 ohms. This combo beats quite nicely in my F150 in a custom ported rear console box. This amp is very efficient. I am on stock electricals and have no light dimming whatsoever. Amp stays pretty cool as well and puts out a very clean signal. My birth sheet from Rockford says 1304 watts at 1 ohm.

This is a very powerful amp in a very small package. I paired it with two Rockford Fosgate P3's in a bandpass box. I would definitely recommend it for those wanting the most for their money. I only have one complaint...the website states that this amp accepts a 0/1 gauge wire for power, but it doesn't. 4 AWG is the largest size that will fit. Overall it is an excellent product at a very low price.
