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.

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.

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.

1000 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
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.
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 - 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
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
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.

I thought this was a great amp to use to run your whole system with only one amp. Build solid and tough! Rockford still has great products. I installed one in both my sons cars and wow they rock. We are using Kicker subs. One son is using Alpine speakers and my other son went with the Rockford pro series speaker.

Wouldn't buy again

February 10, 2013

Being a little older (40) i remember when Rockford was one of the best u could get, I still have Punch 150s I bought new, what a great product. That was not the case here. The item arrived well packed. After that it was all bad. I opened the box to find made in china all over the amp. I spent the day installing the amp. It worked great for the first 5 minutes. The protect light came on and it never worked again. I wouldn't recommend buying something like this online if it can be avoided. I know I won't. There are plenty of company's out there that still make amps right here in the USA. That's what I'll buy from now on.

AMAZING!!! Buy without hesitation!

February 7, 2013

I have this unit installed in my boat fed by a Kenwood KDC-BT952HD. It is driving 8 (yes 8, 4 pairs) MTX 8" two way marine speakers AND 2 Image Dynamics ID10 D2 subs. MTX Coaxials are wired in parallel to achieve 2ohm per channel. Image Dynamic subs are wired in series/parallel again to achieve 2 ohms.

I've always assumed class D amps would only be for sub woofers but with the current wave of manufacturers releasing class D full range amps I was intrigued. I found a white paper online detailing the latest class D chips and how they have been improved (heavy read but worth it if you can grasp even half of it) to increase accuracy and efficiency. That paper combined with the ease of installation (1 amp for 10 speakers vs a typical 3 amp setup) and the potential weight savings (again, 3 amps vs 1) and I figured why not try it.

In my application, the sound quality is simply amazing. Someone running more accurate silk dome tweeters may disagree but EVERYONE that has heard my boat has said exactly the same thing: Painfully loud, crystal clear, full and rich sounding (compared to typical tower/can "systems").

The real magic is in the unit itself. On top of being fairly light weight and small considering the power output / number of channels this thing runs COLD. With 4 ohm loads the amp barely gets above ambient. Even with max load (aka minimum ohms) on all channels, moderate listening levels barely get the unit warm to the touch. That is not to say you can bury it under carpet however... After 4 hours of max effort blasting, it will get HOT. However I have never bumped into thermal protection. This thing is a TANK. With quality 4v discrete inputs I found the limits of my drivers LONG before I any perceivable amp clipping or distortion.

I power my system with one standard size Optima blue top deep cycle... Even driving the amp as hard as I do, 4hrs of run time is no problem for this combo. Proof positive class D is efficient.

The ONLY gripes I have are with the speaker terminals.

I assume the screws are knurled to give them 'bite' on the wire but that 'bite' tends to break the wire. The only way to combat this is to solder the tips (which is a good practice anyway).

The terminals themselves do not accept as large of a gauge wire as I would have expected with level of power output. Not a huge deal but if you are trying to run fat wire, it doesn't leave you much clearance for solder tipping the ends.

I recommend this series of amp to ANYONE who owns a boat or wants big power in a small package. Simply amazing.
