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.
2300 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. 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.
5500 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.
Onyx (Boss)
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.

5500 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
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.

45 - 80 Hz
Subsonic Filter
Allows you to block (filter) ultra-low frequencies that your subs cannot reproduce.
15 - 45 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 - 18 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.
200A x 1 
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.

1 ohm stable

July 15, 2012

They say 1 ohm. NOT STABLE, idiots. I really don't know how can you manage burning amps. I think you are a bit parallel with car audio technique. Don't over range the gain (it isn't a VOLUME, it's a compensator). Bass boost is in about an 18dB range. Again, for compensation. In case you need to keep bass much lower in your head unit without HPF, so long and so forth. If you want 1 ohm (stupidity) buy competition amps. At 1 ohm, you may consider your final amplifier module short-circuited, but it still has to work a bit harder even for BRANDS (eg kicker, cerwin-vega, GZ, etc.).

Good amp if you know what you are doing.

December 10, 2012

I have done a TON of research and this amp IS 1 ohm stable but only if you can give it the power it needs. You can't run this amp without a "big 3" upgrade in your car or it will burn itself out when your stock wiring can't supply the needed power. It is good to run 1/0 gauge wire all the way back to the amp too(a 20 foot spool costs $80-100 because it's that important). Also, you will almost cartainly need a high output alternator and a deep cycle battery. I plan on buying this after I do my big 3 upgrade later this month. I will be pairing it up to 2 Boss AR12D subs. 2400W RMS total 4800W Peak will be my system.

all boss audio is cheap and only for low usage

September 9, 2012

people with boss subs and amps always blow them if you try and use them to there potential. i seen people with 12" boss subs barely even hits and the amp was pretty big but i dont believe it was able to push out what it says it could.. I got 2 15 l7's 10 cubic foot box and 2500 watt kicker amp that **** bumps. kicker all the way. Nothing wrong with alpine or memphis audio. DC are good but expensive.

Installed Correctly

May 1, 2012

All the 1 stars on durability leads me to believe the majority of people dont install this amp correctly. If you are going to have an amp this size you need to do the BIG 3. If you dont "YOU WILL" burn this amp up. This isnt an entry level 4 AWG wire from battery and done amp. You need the BIG 3. You need an extra battery. If not any amp this size burns up.

In reply to kutarescu/ Full review. NDX5500

March 15, 2014

To the guy that says this is not one Ohm stable. First off nothing is short-circuited, 1 ohm has a very low resistance yes, but amps burn up because improper input voltage. I have benched this amp with clamps,volt meter, and a oscilloscope, at 1 ohm right before clipping was 1,891 watts. This is a sub 2K watt amplifier, for 170 bucks that's not bad. You will NOT get the labeled 5500 MAX! That's a marketing gimmick. This amp is stable at 1 ohm. Do not use BassBoost as it's a db gain @ 45 ish hertz. Adjust the gain properly, its not a volume nob.. its there to match your head unit's output voltage most head units have there output voltage labeled in the manual. If you set this amp up right it does the job just expect a sub 2K watt amp. I have mine hooked up to a 18″ PSI Platform 2 @1 ohm.

Powering single 12"

December 30, 2011

Single 12" MD Sound 12-12175 into 1.5cuft sealed custom fiberglass box. Dual 2ohm. Running parallel for 1ohm load to amp. 3farad capacitor. Seat-of-pants-meter is telling me an honest 1000-1500wrms or so, maybe more. Can bottom out the subwoofer at higher power. Haven't clamped the output so just guessing. Great bang for your buck.
