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.

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
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.

300 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%
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 (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 - 500 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 - 500 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.
80 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.
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.
60A x 1 
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.
Amp Bluetooth Connectivity
This feature will tell you if the amplifier has the capability to connect to a Bluetooth device.

good cheap power

April 10, 2008

i have 2 of these now powering my 2 ma audio hk100xc's. they do have some kick and are nice but dont have too much power. they are how ever under rated as the birth sheet for both of mine said that they do ~ 400 rms and 1200 max. so that's about what your getting if you can get the power to them. anyways these amps are fairly decent and you really cant go wrong.

July 25, 2012

Fantastic amp, especially for the price. I am pushing a 12" JL Audio W3 with it and this amp has plenty to spare. With the gain control at 4 (out of 10), it's louder than I need and typically keep it dialed back with a volume control unit on the dash. Easy to install, tons of power, and reasonably priced. What else could you want?!?!

I love Rockford Fosgate amps

August 21, 2012

First thing I must say is that this monster is so tiny for the amount of power it puts out. My iPad and this amp are exactly the same size! The birth sheet that was included shows the total power this thing gives out when the car sits at a 14.4v

418 watts RMS @ 2 ohms
286 watts RMS @ 4 ohms

I had this amp hooked up to 2 Rockford Fosgate P1's and they sounded fantastic. Then I sold the subwoofers and went with a new 12" RE Audio SEX subwoofer which sounded absolutely phenomenal. My car is black and this California heat isn't helping but this amp never reached the point to where it got hot enough that it needed to shut off. Not even in the summer where would have days of up to 100-108°
One last thing, the Punch EQ isn't provided but I definetly recommend paying an extra $20+ for it because it comes in very handy when needing to control the bass rather than having to toggle with the amp you can simply do it from the comfort of the drivers seat :)
For the price that Sonic Electronix has to offer you would be a fool not to buy it.

Not enough for my set up

January 7, 2012

I have this thing hooked to a single 12" Alpine type-r 600 watts rms and it isn't doing anything, I think my battery is going bad which probably explains this problem. I'm starting to think my trunk doesn't have a solid sound because the spare isn't in there and the flimsy cover is a little warped so I think I'm losing a lot of sound cause it sounds okay with my seats down. As far as overheating, I have no explanation cause I have a good short ground and my stereo tuned for best s/n ratio and the amp was turned to 4 gain out of 11! I've just ran into a million problems with all my stereo components ever since I got my car and it's not my first.

Did a custom install on Wrangler, sub in center console box facing down behind front seats, Kicker l5 8" this sub/amp combo makes owner very happy. Its loud enough for him. He is deaf in one ear, and can't hear out of the other. the other sound comes out of kappa 4x6 plates front and kappa 6x9 in rollbar boxes rear, profile 4 channel amp. his p300-1 says 401 watts at 2 ohms. Cleanest install of mine to date.

powerful little sucker!

March 13, 2011

I bought this amp to push my JL Audio 8W3v3 based on reviews by fellow purchasers. I have to admit I was very skeptical about both the amp and sub being that I had never owned an 8 inch sub before. When the amp arrived I immediately thought "oh crap, this is tiny". Don't judge a book by its cover, this thing is amazing! I have it wired to a lowly 4 ohms and it pushes the heck out of that JL at half gain. With the optional bass remote all wired up I never have to touch the amp again. Fits under the front seat easily and stays uber cool. Power birth sheet says 286rms at 4 ohms and 414rms at 2 ohms.
