Power Specifications - Full Range 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.

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.

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.
Onyx (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.
5
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.

1000 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.

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.
1/0 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
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.
No
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.
50A 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.
No

MB Quart Onyx OA1100.5 Amplifier, absolutely love it. It had been 7 years since my last system build and high quality was not inexpensive back then, today there is lot's of competition and you can find affordable high quality if you look closely, MB Quart has been synonymous with high quality as far back as i can remember and that's longer than i care to share with you. Most people choose a 5-channel amplifier because they want both front and rear fill plus the subwoofer but i have no use for rear fill, channels 1 and 2 drive a pair of 2-way components, channels 3 and 4 run a pair of dedicated tweeters to create soundstage and channel 5 sends 500W rms to a pair of 12" subs wired for 2 ohm mono in a sealed enclosure. MB Quart helped to transform my Ford E150 into a concert hall, with MB Quart you don't need to buy reference grade equipment to get reference grade sound and knowing how good their "low-end" amplifier sounds i can't even begin to imagine what their Reference class amplifier sounds like, perhaps one day in the near future i will discover for myself but in the meantime i am thoroughly enjoying my Onyx class Amplifier and have not had one single problem, i won't hesitate to use MB Quart to please my very discerning ears....

Nice but overrated amp

November 7, 2013

I've had this amp for a week and wanted to give my sub time to break in (Phoenix Gold 10" SL). I used an rms meter & clamp (Fluke) to check the output of the sub channel on a few test tones. The sub amp did ~190 watts rms @ 2 ohms. Channels 1-4 was pushing ~38 watts rms @ 4 ohms. I was not pushing the amp to the max because I wanted a good clean signal and sound. My Phoenix Gold amp is clearly louder and is rated at 300 watts rms. That being said, the sound is very clean. The x-overs, gains, and Hz are not as accurate as other amps, but they work if you take your time and use your ear. The amp itself looks so much better in person than the pictures on Sonic. It's a little bigger and heavier than one would expect from such a budget amp. The amp has been running cool under the passenger seat of my Titan. Everything is clearly labeled and unless you are new to car audio, you can plug and play this amp if you are replacing another one. I didn't expect this amp to really do the rated power at $200, but it is overrated, I can't give it 5 stars because of that, but it's been a nice amp for a low power budget system. It is a fine amp as long as you know what you are getting.

Good but not that great

September 28, 2013

I tried to use this with a LOC and the over all outcome was a little less then desired. Clean sound but i found it difficult to tune. Keep in mind i was using stock headunit and LOC so..... Overall combo was not so good.

Decent Value

September 17, 2013

Installed this on my boat driving 4 speakers and a sub at 2 ohms. This replaced a HiFonics 1100 watt amp that recently blew up and short circuited which I also purchased on Sonic Electronix. Really wish that hadn't happened! Not quite the power output as the HiFonics, but after an hour or so of adjusting the crossovers and hi-low bandwidth and sub output adjustments, it sounds pretty decent for the price for a 5 channel amp. I would recommend for the price.
