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. 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.

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.
PDX (Alpine)
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.
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.

600 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.
Not Bridgeable
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.
0.004%
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)
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 - 400 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.
92 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.
Yes
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.
20A x 4 
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.

Ordered the alpine PDX-M-6 and was at the door In about four days. It was packaged to avoid damage. Hooked it up in the pontoon and let it bump. Very happy with the order and response from Sonicelectronics. I would highly recommend.

February 8, 2011

Alpine makes a great product. This has all metal construction and puts out more power than they are rated at. Mine was birthed at 694 Watts RMS. It has such a small footprint for the power output too. This amp is great for my power hungry eclipse 8010d subwoofer. Its tight crisp bass the way I like it.

good amp

October 18, 2010

got 2 of these running 2 Eclipse 700 watt RMS subs. I have the gains under half. I do have alternator whine but im thinking its the MTX req5 doing it the amps seem to produce low hiss. Can't complain. Very tiny amp and stackable. Love the quick disconnects

Great value/clean power, but no bass boost

May 18, 2015

Bought this on sale, and I am very pleased with the value for the price.
I believe it delivers its advertised power and more. The design is nice and looks great installed. If a bass boost adjustment is important to you (after not having one, I really don't miss it), be aware that this amp does not have one. My final recommendation really depends on the purchase price. I certainly think the quality and power is there...

Fantastic amplifier.

June 27, 2011

Alpine has created an excellent product with this amplifier. Sonically, it is among the best I have heard. Great resolution, slam, detail---Sonic excellence. Class D amplifiers are now state of the art. And being class D, its power draw is ideal for an auto application. The amp syncs seamlessly with my Alpine deck. I have no complaints with this amplifier.

Excellent Amp!

March 9, 2011

I love these amps! I'm running two of them, with each one powering one 12" Alpine Type R. Sound is clean, tight and crisp. After almost an hour of continuous playing during my rides to and from work, this amp is just barely warm. No complaints whatsoever.

Great amp

May 1, 2012

I bought this amp for my regular cab ford ranger and was not disappointed. I was severly limited on space and the fact that you could stack these amps on top of one another was a huge bonus. It works great to provide great quality sound but also gives you that big burst of sound when you want it. Ive beat this thing for hours playing music, blasting it and everything in between and it was still cold. Ive tried almost everything to break, minus hitting hit, and i just wont break or die.

I have a Alpine PDX-M6 amp. I have an Image Dynamics ID10 V4 Dual 4 Ohm 250 Watts RMS Subwoofer. Am I good to go with these components as far as compatibility?

Any and all suggestions are welcome.

Image Dynamics ID10 D4 V.3
Best Answer: Hello,

The 600w RMS @2ohms (Sub in Parallel) is a bit more than Image Dynamics' Recommended Power Range of 100-400 watts rms; This doesn't make it a 'terrible match', but it does mean you - as the user - will need to ensure that the setup is set up properly, you aren't clipping, and you do not get trigger happy with the volume/gain/level/etc... Keep in mind, the amplifier is likely capable of doing well beyond its rated figures, so this can make for a precarious situation.

The rest of the set up is pretty spot on. The SPS are also a bit overpowered, but that isn't a huge concern at all.
