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.
300 watts x 1 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 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.
500 watts x 1 channels
RMS Power @ 1 ohm
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 1 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.
Not Stable
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. 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. This is the peak power output for the amplifier's 5th channel.
1000 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.
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.

500 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.
8 AWG
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
2 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.
1%
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.

50 - 200 Hz
Subsonic Filter
Allows you to block (filter) ultra-low frequencies that your subs cannot reproduce.
15 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.
100 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
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
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.

Great amp!!

December 22, 2011

This is a very good, and powerful amp. It was easy to install and has good output. I would perfer a little more RMS power, but a very well designed product. Hits well with an Alpine Type-R. Very pleased with this product.

Alpine quality!

August 30, 2011

I used to own this amp and had it powering 2 Type E 12's in a sealed box and I have to say I was skeptic when I first bought it, but all that was gone after I hooked this bad boy up! I couldn't believe how great this thing performed even @ high volumes it never cut out and was only slightly warm to the touch even after a half hour of playing! For the money on a 500 RMS system and performance with durability all built in this tiny little package, you cant go wrong and you will not regret this purchase! P.S. I sold this setup to my good friend about 5 Years ago and he's still bumping it and still sounds as good as it did the day I bought it! Amazing quality!!! A+++

So powerful! So clean!

March 12, 2013

I just recently got this amp and I am powering a pioneer TA-W310D4 12 inch champion series dual voice coil subwoofer. I have it running at. 500 watts at 2 ohms. All I have to say about this amp is that it is perfect. Easy to install, did it in about an hour with a couple of friends. It is so clean and powerful. I have never heard such sweet sounds coming from a subwoofer. I highly recommend this amplifier to anyone from a car audio beginner or an experienced car audio wizard.

Very slick amp!

March 5, 2013

I own a couple of Alpine amps for my system (MRX-F30 for highs and MRP-500 for sub). The amps look almost identical and when installed adjacent to each other, it's a beautiful pair! These Alpine amps' size look deceiving, because once you hold them up, you'll realize that they're as solid as a brick...very good quality comstruction. I currently have my MRP-500 powering a single IDQ12 DVC @2 ohms in a sealed box. All the signal is controlled through my Clarion EQS746 EQ. Boy does it really rock the car! I only have the gain up 50% in order to match my highs. I tuned it with my sound test cd at high volume, so I know it can kick A LOT harder than how I'm currently setting it up, but then it's a totally SQ system. Still, I don't play it loud in my neighborhood because I don't want any attention and don't wanna bother anyone. I think the most important thing if you're planning to purchase this amp is that you need to pick your subwoofer carefully. Make sure the sub you're gonna use with it is 2 ohms and rated for around 500w RMS in order to harness the maximum performance out of your equipment. I believe this amp truly puts out at least 500w RMS of pure power, so it will likely blow most low-power subwoofers at prolonged high volume. This series of Alpine Class D amps seem to be extremely efficient, not affecting my car's electrical system one bit, even at my max listening levels. The only negative thing I could say about this amp is the design of the power terminals. It's a set of standard screw-down plates, not unlike the ones you'll find on most speaker terminals. However, it could accommodate an 8 ga power and ground cable without much problems. To ensure maximum connectivity, make sure to crimp appropriately-sized spade terminals on your 8 ga cables, then screw it down tight. My main power cable is a fused 4 ga, ran down to the trunk where it is splitted by a fused distributor block into 8 ga cables for wiring to the amps. Works like a charm.

Awsome Amp!

September 21, 2012

I have currently own this amp for 4 years and it's awesome! I had a rockford P3 12 and It blew it. So I stepped up an alpine type R 15 and it hits great. I messed up though and bought the 2 ohm sub instead of the 4 ohm. So in stead of 500 watts I'm only getting 300. But with that said it out performs my buddies Rockford p3 15 and on half the power! Deffinantly recommend this amp!
