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.
475 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.

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.
Reference (MB Quart)
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.

1000 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.
1/0 AWG
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
1 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.
0.10%
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)
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.

30 - 250 Hz
Subsonic Filter
Allows you to block (filter) ultra-low frequencies that your subs cannot reproduce.
15 - 35 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.
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.
80A 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.
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.

No
Hi-Res Audio Compatible
This feature refers to if the product is capable of Hi-Res Audio (HRA) playback.

I have one hooked up to my RE Audio SXXv2-12D2 and it makes my whole car shake!! Reall great product and great brand too. I've had it for about a month and I do check to see if it gets hot cause the sub is at 1100 rms and the amp is at 1000w and it does a great job handling it's power it never gets hot so I highly recommend this product!!!

This amp is good for what you pay. Does rated power, looks very clean. I haven't had any performance issues yet, completely satisfied.

There is, however, one big issue. two of the four screw holes for mounting (the 2 in the rear) have no barrier protection from the inside of the amp. So if you drop a screw while trying to mount it, you need to remove the entire side panel and VOID WARRANTY. Based on this alone, i would not suggest this product - buy something else without a major flaw. Not sure what mb quart was thinking, but having a huge opening from the outside of the amp to the actual board is a terrible design. I've never had an issue like this with any other product.

Good Amp, especially for the price. Can't shake a stick at that.

August 4, 2015

I just installed this amp on a RE Audio SEX10V2-D4 in a ~1cu/ft box tuned to 35hz. I'm unsure how much power this is putting out. I wish I could test but somebody stole my multimeter with clamps to measure amps. Although, it definitely is moving my 10 good and the sound is very clean. I am impressed with how good this amp sounds for such a wonderful price. As long as I don't have any over heating issues in the future, I will definitely buy one of their larger amps in the future for my next install.

I'm going to say 5 for durability RIGHT now. Only because it would be unfair to rate it other wise and turn people away with a poor over all rating. If something changes, I will add another review.

I'm going to leave features at a 3. There isn't a Q setting,a low or high voltage selection for input, and the manual doesn't list voltage output to voltage input settings. So there isn't a definitive number to read for the off the multimeter when setting gain. They give you a clock orientation in reference to voltage input not associated with ohmage

amazing amp for my duel 12' mtx subs
Baron K on Mar 21, 2016
I bought a MB quart 12 inch PWM304 and needed power to drive it. Wasn't decide if I want 1 or 2 so I took this amp that can drive them both on 1ohm and that can drive 1 at 2ohm. Even if 750W at 2 ohms is more power than needed by the sub alone (500W), there is no problem of having a stronger amplifier (if you don't crank the gain at max). The price was really good for the power available.

Hello!! I am looking at purchasing a WCC 1600.4 by MB QUART. I have never owned an SQ amp...as far as install goes, what are the recommendations for cooling and clearances..I am used to A/B amplifiers. For my sub I have picked out the MB QUART RA1000.1 class D...and I know they don't get near as hot as A/B amps but what about the class SQ's?

Best Answer: I couldn't tell you a temperature but it doesn't complain about being in my trunk with no airflow and three identical amps next to it. Proper electical is key to that though. If it isn't getting the amperage it needs, it's going to run hotter.

Is this amp truly stable to a 1 ohm load?
Don P on Apr 20, 2015
Best Answer: Hello Don,

MB Quart would not provide a 1ohm rating if it was not 1ohm stable. So, yes. Some manufactures out there are misleading, but that is not the case with this manufacture. With a proper setup, the amplifier will do well at a 1ohm final impedance.

Max Peak output @ 1ohm?
A shopper on Mar 6, 2015
Best Answer: Hello,

'Peak Power' is a useless figure, so we try - if allowed by the manufacture - to not include it. However, sense you asked, its 2000w Peak @1ohm . Again, that figure is fairly useless, so please make sure to base your matches off the RMS figures.
