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.

75 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.

100 watts x 4 channels
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.

200 watts x 2 channels
Peak Power Output
This form of power rating refers to the maximum amount of power an electronic device can handle or output in an instant without damage occurring. Often times this maximum is achieved during a brief musical burst, such as a drum accent, or low bass hit.

Some manufacturers display peak power ratings on the face of their products to increase the appeal to consumers. The RMS power rating is more accurate, and we recommend using it for product comparison.

800 watts x 1 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.

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.
4
Total Peak Power Output
The total peak power output is measured as the wattage per channel multiplied by the number of channels, and is calculated at the lowest level of operating impedance.

It is measured during a brief musical burst, such as a sudden drum accent. Some manufacturers display peak power ratings on the face of their products to increase the appeal.

The RMS power rating is more accurate, and we recommend using it for product comparison.

800 watts
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.

400 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
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.
0.06%
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.

40 - 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.

40 - 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.
95 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.
No
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 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.

I LOVE SONIC

June 12, 2012

The amp they sold me really packs a punch its small compact size fits perfectly in my car. Another place tried to sell me a amp i didnt need even my instaler i brought it to tried to tell me what they sold me was no good, but the installer who was doing my car told me not to let them talk me into sending it back. That the stuff i bought from sonic would destroy what they had to offer. I will deff recommend sonic to everyone i know

This amplifier met my expectations. Although my previous amps where very good brands and AB type, this D type unit performs very good and offers more power than AB´s in a smaller package. The D type amp supposed increased distortion has not been noticeable in my installation. I definitely recommend this product and recommend Sonic Electronix.

An excellent out of the box, plug-n-play kind of amp. Very compact, stealthy. It's sturdy, durable and you can easily swear on its build quality. Above all, looks good too. Performance? Well, I used a couple of amps and this one didn't need any kinda tweaking, as if it just understands what speakers it has to drive.

Good value amplifier!

February 19, 2010

This amp has a great sound, small footprint, and low energy consumption (class D "digital" amp). It is a no frills amplifier that puts all its power into sound (not flashy lights and other bells and whistles). This amp is a great value for the money. The highs could be a little more clear, but for the price I don't think there's a better digital 4-channel amp on the market. Pioneer did a great job with this one.

Since it's a new amp, I can only guess on its durability based on Pioneer's track record.

The only downside I can see is that the amp has the "old style" connections for power, ground and speakers, not the newer, more convenient allen wrench connections. Presumably this was done by Pioneer to save money, passing the savings on to the consumer. That, with some lack of definition in the high end, is the only reason I ranked it "4" instead of "5". In actuality, I'd rank it "4.5" if this were an option.

February 20, 2012

If you have space or power requirement considerations, this amp is the solution. It draws less current than comparable output amps, and is small enough to fit in tight spaces. Very clean sound, adequate power to drive 4, 2 ohm speakers, nicely overcomes road and exhaust noise in my Corvette convertible at highway speeds with the top down. Great value.

Great Amp

November 16, 2010

I have this amp installed with a Pioneer double din 4200. I have two sets of the Infinity Kappa Components. The sound is incredible. I had each wired to one channel, but the amp is REALLY under rated. I already blew two sets. Luckily there were replace by Infinity. Now I have a set wired to one channel so I am only using two channels and they still sound great at only half the gain.

Great power, great price!

October 24, 2012

Powers a JL 150w 6 1/2" Sub, and Infinity Perfect 6.1 components.

For the price I paid, this amp is by far the clear winner, unless you want to pay an additional $200 for a newer set of connectors and possibly a slightly higher output.

I personally think this amp has been under rated as it has no trouble supplying the power to the speakers and sub.

Profile of the amp is small, not quite small enough to fit under my MR2 Rev. 2 seats without trimming the carpet, but would easily fit under a station wagon seat or Corolla.

Well worth the investment if you're not sponsored or have $1,000,000.

August 23, 2012

This amp had exactly the features I wanted at a great price. The best thing about it is that it keeps cool enough and is small enough that I was able to install it behind a plastic panel for a completely stealth install. The power this amp puts out is clean and crystal clear, though some of the midrange has a tiny bit of a "grittiness" to it, but this is to be expected from a full range class D amp.

Great Amp in a Small Package

December 7, 2011

This amp replaced a much older, larger, and less powerful Pioneer 4-channel model I had been using. I continue to use 2 channels to power my front (component) speakers, and bridge the other two channels for a trunk mounted sub in my 09 Civic Si.

Another advantage is how much cooler it runs. This isn't really a requirement for me due to where I've mounted it, but for those that are considering mounting in a confined space like behind or under a seat, it could avoid a melt down (had that problem with a Sony amp).

It took a while to "balance out" the gain and high/low pass filters for optimal sound and performance, but I'm really pleased with the results.

great little amp

November 29, 2011

I’m using this amp to power a set of pioneer 5-1/4 component speakers in the front and a set of pioneer 6 x 8 three way speakers in the rear door of an 02 Ford Escape. Overall, I am pretty happy with its performance alongside a powered 10" sub. I don’t know how it would sound without the sub or if you powered a sub off it too. It is a great fit, out of the way in the cargo area of my SUV. Seems pretty durable too. I was moving a large metal chair that had shifted and hit the amp pretty hard. It put a little gouge in it but no other noticable damage.

One issue I have had is when I connect my ipod to my pioneer head unit, there is a very low but noticeable white noise. Like the sound when you (use to) start a cassette tape. I can’t think of any other explanation. It may be the cable, head unit or my crappy older ipod but I didn’t notice the noise until I had the amp in. I have had a little trouble tunning amp to my speakers but only because I mostly don't know how. I am a diy'er and don't like paying people. I think I got it pretty close to its best sound. Again, that's according to my ears. All in all, this was a great upgrade to my sound system that sounds great to me. Very clear and balance sound.

I have this amplifier and just recently noticed that it's rated at 800x1 max power. I've been running a set of mbquart components on the front channels, and bridging the rear channels for the sub, but 200 watts rms is not enough for this sub(polk mm1040). How can I wire the sub so it receives the full 800 watts(400 watts rms, I'm assuming) Please help??
William T on Jan 1, 2015
Best Answer: Hello William,

Unfortunately, there is no such thing as wiring an subwoofer/amp in a specific way so it can provide more power. You are obligated to the restriction/parameters of the setup. Assuming it is currently wired properly, you have reached the full potential of your setup. The 800w you are referring to is the MAX power, so its not an obtainable figure. We suggest getting into a Monoblock, for just the subwoofer, to get the ~350/400w RMS that the MM1040 is asking for.
