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.

375 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 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.

750 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 speakers or subwoofers equals 1 ohm, 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.

1500 watts x 1 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.

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 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.

1500 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.

1500 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.
1 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.
.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)
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.

35 - 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 - 9 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.
70A x 2 
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
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.

Love this amp!

June 10, 2013

I had been looking for a newer mono amp to replace my California Profile MS600 and had recently replaced my 4 channel with their MB Quart 480 and loved it so I bought this one because I knew it would be a great addition to my sound system. If I ever need to replace it I am sure to find the current model of Mb Quart and buy it.

October 3, 2010

I have 3 MB Quart amps in my setup and this one powers my 2 MB Quart 12 inch subs. This amp is built like a tank and pushes my subs where I need them to be. I am running the subs at 2-OHM for 750W RMS and my system pounds. Get this amp you will not be disappointed.

Good Amp, Great Power

September 5, 2010

This amps is filled with power. I had it pushing my 2 Kicker L5s. It made one of them pop when only set 3/4 way. Also love the bass knob. You wont go wrong with this amp it never cuts off or overheats.Filled with power and is made by maxxonics which makes hifonics so in reality same amp as the brutus 1600d. This amp will slam and can take the abuse. Be ready 2 make your speakers pop because it made my L5s sometimes on only 3/4s way up.

A Solid Buy

August 30, 2010

This amplifier is a solid buy no matter how you look at it. At its price point, it's near impossible to beat. It puts out rated power, it's built like a tank, and it's one of Maxxsonics best products in years. In comparison to a Sundown SAZ-1500D (I did a straight swap in a head to head comparison), there was no audible difference. Overall, I am satisfied and wouldn't hesitate to buy another.

MB Quart DSC1500.1D

August 15, 2010

I recently bought this amp from Sonic Electronix, and it was at my home in 3 days. The amp was package very well. The amp was small and heavy and had a nice design and easy to install. PROS I bought this amp, because it was more efficiency then the Audiopipe AP15001D. I just wanted a amp with alot of power to push almost any subs and with some sound quality. This amp is a little stronger then my subs, but i like know i can upgrade and i still have power to back it up. Make sure you have at least the big 3 upgrade to get the most of the amp. And latter buy an extra battery. Anyway overall the amp is loud and put out rated power and very efficient, it wont get warm if you have a good electrical. CONS I think they could of put quality MOSFET and component for more efficiency and for long healthy life. Other then that i don't have any to say bad about it. I haven't had a problem. I would highly recommend this amp to anyone who want power and quality sound. You don't need to buy high end amp for bass. This amp is just as good, but you save money. If you just want to be heard and have major bass, then consider buying this amp. For major bass head and competition competitor you mite want to get name brand or the MB Quart DSC2000.1D.

Great amp, great cost.

June 8, 2010

I purchased this amp, and the first one that was sent to me was defective from the factory. Sonic's was great about getting me my replacement. Now that I have a replacement, this amp is a beast! I have it on a single AudioQue 10" SDC2.5 sub wired at 2ohms. I did a 138.6 2 52hz. My system has been clamped and it was 800w on the current setup. Great amp for the cost couldn't have asked for better.

Strong, reliable, and wonderful watt per dollar value

May 21, 2010

This amp was a wonderful choice for a budget build. Just because you want something decent and reliable that puts out more than what it is rated at doesn't mean you have to buy Rockford, JL, etc. This amp put out about 1680 watts RMS at 1 ohm when examined on the oscilloscope and held up nicely doing so .Does run a little warm, but plays nice and strong.

Rock Solid Power

April 30, 2010

Pros: Heavy Duty Construction: This is a solid chunk of Aluminum extrusion here (the side fins are 1/4" thick !!! ) .. as a result it does not even begin to get warm to the touch, even after hours of abuse, It literally is cold to the touch ! This means a long healthy life of beating the heck out of your subs. Power vs $$: So to find a high output amp in this price range, means you will be buying a china made peace of shhhh... right ??? ... wrong, A lot of new-schoolers may not have heard of MB Qaurt before , but they have been in the car audio thing for a long time and have always made quality stuff and where well known for there component speakers back in the day. As far as the power rating goes... its all there , I have already blown one of my subs with this and will be looking for 600w RMS plus subs to replace these with. Gizmos: Plenty of features here to play with for a Monoblock amp, you can tweak and tune to your hearts content. Beastly Beauty: The pictures really don't give due justice. This is a really nice looking amp, the disc arc on the front of the amp is not some crappy snap on plastic piece , its polished aluminum from what I can tell. The amp is just a sexy beast, I really like the look of my JL Amp and this is a very nice compliment to the amp collection. Cons: Interface: The RJ-45 jack used to connect the sub control knob is a cheap way to go in my opinion.. I would like to see a screw in style jack used here instead.. but again your paying $200 for this amp :) , also the power and speaker terminal blocks use a philips head instead of a Hex key.. not sure why they did this but Hex is a much more resilient design than phillips in my opinion. That is all I can really complain about, I was a bit concerned with buying this amp at first, but I am glad I did now. No regrets and I would recommend this amp to my family and friends... and certainly to you as well. Bite the bullet and slap down the credit card.. the "old lady" will forgive you when your vibrati'n her seat with this bad boy =)

(its been metered) definitely would recommend this to anyone who want some insane power on a budget

This is a very nice amp for the money! I would recommend to anyone who has power hungry subs-looking for a beating. I have it pushin 2 PPI Pro 12's and it is insane how loud it is in my 4 runner. I almost cant stand it at full power. The only problem I had was it melted the wire connectors inside my box. Make sure to get high quality 1/0 gauge power and ground or you wont push a full 1500 rms. Either 10 or 8 gauge speaker wire and high quality connectors as well ! THE REASON I GIVE IT A 4 OVERALL -is sound quality not really a high end amp. it drives lows very well but falls short in the higher sub Hz.
