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 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 
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

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.

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.

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.

I purched this amp for the size and it being a D class amp. I am happy with the sound and the power. The only down side is the old style power/GND/SPKR connecters. Although it is really not that big of a deal, it detracts from the looks of the amp.

I installed this amp on my 25 foot fishing boat to power 8 coaxial 8" spaekers, and it sounds great. It is loud when out at the sandbar, and sounds great when you are going 40 mph on the water.

Excellent!

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.

All about the sound

July 19, 2012

Every amp I put under my seat got hot enough to fry an egg when I pushed it. Even low volume the others (class A/B) would get hot. This is my first class D for my mids & highs. This amp gets warm normal playing and I managed to get it hot when pushed to extreme. There was a difference of less heat, but for class D I was hoping for cooler. Now for the sound: I had four other amps for my front in the past and they all had slightly different sound signature. This one is no different. I would say the low level resolution is slightly exaggerated, while also somewhat of a boost or extension past the upper highs. This creates a sound that, to me is best described as very "high polished" and "shiny." The only drawback is the depth of field is not as deep as I have heard elsewhere, but the sense of "shiny, polished" clarity is impressive nonetheless. Also, it does not have either the sweet "MOSFET" sound, nor does it have the dry "bipolar transistor" sound. Its sound is unique and of its own, and never harsh when driven hard, just a lil' "glassy" at max volumes. This lil amp blew FOUR OF MY INFINITY SPEAKERS! Both tweeters first, then woofers, as they were all 2-way 5x7 speakers, and they were only pushing the kids/highs. The amp would shut volume down into protection just "after" it burned them! I was going to upgrade to the "Kappa Four" amp to see if I liked the sound, as I prefer a sweeter "MOSFET" sound than this, but I found a better speaker match than the Infinity, which are too brittle sounding in details and blew out. With my new speakers, the sound is more natural in upper mids to highs, and just right without blowing out like the Infinitys and almost half the price! They are the "Precision Power PPI PC.572" 5x7 2-ways at 3 ohms. Also with external crossovers just like my Infinity Kappa I blew! So, I will keep this setup until something dies!

Audio System Revived

June 25, 2012

My stock 2003 Ford Ranger Edge system was not doing it for me anymore so I opted to get a single DIN Pioneer Stereo, this Pioneer amp, 6x8 Pioneer Speakers, and Kicker wiring. I am so pleased with the performance of this amp that I will be looking for pioneer parts when adding a small sub setup to the truck. In 4 channel mode this amp lets the truck be extremely loud and sound very crisp for tailgate parties and everything.

Very amazed

March 1, 2012

Originally I purchased this amp to power the four polk 5x7's in my wife's Mazda 5. There's really no were to place an amp so I ended up putting it in a storage compartment under one of the center row seats. I was pretty worried about it overheating in such a small space (only enough room for the amp) but every time I checked it was never warmer than ambient. It performed very well providing great sound at all volume levels. I never experienced any issues. We ended up selling the 5 and bought a Town & Country. Turns out there is even less space to place an amp in a larger vehicle so the amp is nestled under the drivers seat. This time it's powering four Infiinity 6x9's. We'd been running these speakers off the head unit for about 3 months and weren't very impressed. They sounded better than stock but didn't have the rich full sound we wanted. After installing this amp I'm reconsidering putting subs in the van. The highs are amazing and there's is more than enough bass to rattle everything in the van. This was probably the best money I have spent for my stereo.

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.

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.
