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.

150 watts x 2 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.

225 watts x 2 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.

450 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.
GM Series (Pioneer)
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.

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.

900 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.

450 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.
0.05%
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)
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 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 - 12 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.
30A x 2 
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.
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
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.

Great little amplifier!

December 29, 2014

This is a great little amplifier. I am using it to drive a a pair of component speakers mounted in the front doors of my vehicle. The speakers are rated at 90w x 2 RMS. I had originally tried to power them with an Alpine MRP-T130 that provided 50w x 2, but at higher levels the amp was entering protection mode. This amp is lightweight, but more than powerful enough at 150w x 2 @ 4Ω. The power easily provides excessively loud levels without any perceived distortion for hours on end. I feel that this product represents the best value of any stereo amplifier in this price segment.

Pros:
- CEA-2006 compliant
- Powerful
- Clean (great for highs or subs)
- Very reputable and experienced brand
- Light (improved gas mileage and performance for vehicle)

Cons:
- No single-band parametric EQ if using for a subwoofer
- No remote bass knob for subwoofer
- No high-pass crossover
- Not 1Ω stable (but you shouldn't expect that in this price range)
- Light (Class AB amps tend to be heavier with greater quality amps, but no problems so far)

Best Answer: without actually seeing your set up, the best I could tell you is to take a look at your power and speaker wires. may have some breaks that are causing the wire to get hot. Could also check the mounting point for your amp, if your not getting proper air flow to keep the amp cool, or if its mounted on something that cant handle a little heat.

how do I get power output closer to the 900 watt range ? gm a5602
Donnie B on Apr 29, 2016
Best Answer: This model has a peak output of 900 watts. Your RMS is 450 at 4 ohm bridged. If you attempt to steadily pull the peak output your amp will overheat and possibly fail. To reach your 900 watts you will need a new bigger amplifier.

The instructions to the pioneer GM-A5602 Amplifier states that when it comes to Bridging sub-woofers to do not install or use their amp by wiring speakers rated at 4 ohms or lower in parallel to achieve a 2 ohm or lower bridged mode. Amplifier damage, smoke and overheating could result from improper bridging, the amplifier surface to could become hot to the touch and minor burns could result. To properly install or use a bridged mode and achieve a 4 ohm load, wire two 8 ohm speakers in parallel with left positive and right negative or use a single 4 ohm speaker.

So is what their saying is that you cannot bridge two pioneer 12" TS-W304R 4 ohm Sub-woofers with a pioneer 2 channel GM-A56023 Amplifier?

Now i thought most subwoofers were rated at 4 ohms, so does this mean you cannot not do it or should not do it? its been awhile since i have toyed around with car audio equipment and bridging two subs with a 2 channel amp used to be like the normal thing to do....

So i guess what i am really wondering is what is the best set up with that amp and two of those subwoofers together installled in a nice ported enclosure?
Kraig on Jul 9, 2015
Best Answer: Hey Craig,

Pioneer sure made something easy extremely difficult to follow. What they are saying is that when you BRIDGE the amplifier you CANNOT wire your driver(s) to anything LESS THAN 4OHM.

-So is what their saying is that you cannot bridge two pioneer 12" TS-W304R 4 ohm Sub-woofers with a pioneer 2 channel GM-A56023 Amplifier?

Correct, you CANNOT BRIDGE the amplifier AND wire those two drivers TOGETHER. That is because wiring the those two drivers together in PARALLEL will result in a 2ohm load, and wiring in SERIES will result in an 8ohm load. 8ohms isn't "Bad" but you won't get very much output.

-Now i thought most subwoofers were rated at 4 ohms, so does this mean you cannot not do it or should not do it? its been awhile since i have toyed around with car audio equipment and bridging two subs with a 2 channel amp used to be like the normal thing to do....

No. Saying 'most' subwoofers are any one specific impedance would be hyperbole, considering there are four 'typical' configurations to subs. (e.g. Single 4-ohm, Single 2-ohm, Dual 4-ohm, Dual 2-ohm, etc..). Im sure you once saw two drivers on a two channel, but the '2-channel for subwoofers' method is as dated as a VCR is.

-So i guess what i am really wondering is what is the best set up with that amp and two of those subwoofers together installled in a nice ported enclosure?

Your ONLY option here is to give each subwoofer its own channel and NOT bridging the amplifier. To reiterate bridging this amplifier AND wiring up the subs in parallel WILL harm the setup. So the only option left is simply giving each driver its own channel, which will limit the power to 150 watts x 2 chan. .

The "better" match would have been a MONOBLOCK, which are built specifically for subwoofers - as opposed to Full Range Multi-Channel amps that are intended for door speakers, but are still used for subwoofers. The Pioneer GM-D8601 is the 'better' match.
