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.
900 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.
1800 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)
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.

1800 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.
4 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.
.01%
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)
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.
105 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.
25A 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.

Great amplifier for the price

February 28, 2013

I got this amp with a 1,400 watt pioneer sub and it bumps. My friend recently got a kicker amp and sub and mine hits much harder. If you're looking for a great cheap buy, this amp will do just fine with one sub. The remote sub control is great. You can put it almost anywhere (like out of the reach of your passengers). I haven't had it for long but it has yet to shut down from overheating, even with it mounted directly on my sub box.

Boss oynx 1800.1 mono amp

July 20, 2012

This amp is overrated by quite a bit it realistically only puts out about 250 watts RMS if that is all you need then this is the amp for you. There is nothing wrong with it. It works fine but is merely underpowered.

January 27, 2012

If you have a speaker that requires more than 200 watts don't buy this amp. I got it to push an Alpine swr 1043 and it barely moves with all adjustments turned all the way up. I do not recommend this amp.

AMAZING AMP!

September 13, 2011

I have had four amps and I have to say that this amp is truly amazing. I have one 12" flat, Pioneer sub that is capable of 1800 watts, max. This amp was able to fulfill that and pump out bass beats like none other. I am truly impressed. The installation was very simple as well. Classic, but simple. It is also very sturdy and durable. My only complaint was with grounding it. I had to ground it with 2" of bear cable in order to get a good enough ground. However, I won't diss on the amp with that because it could have just been my car.

Love this Amp!

May 8, 2011

Been using this amp for 6 months to power 2 15" Boss Subwoofers and it is awesome. The quality of the amp is excellent and is very well built. I have a Jensen amp for my component speakers and this Boss amp blows it out of the water, I should have gotten this amp for those too and I might still. The wire hookups are great because they use set screw clamping so no trying to fiddle with fitting wires around a screw plate. It even comes with a remote bass level knob. I can easily give this amp 5 stars.

This amp is amazing for the price, I have ran this thing at 1800 watts on my Boss 12" and it doesnt get hot, and thats pushing it for a good half hour straight. I was skeptical of buying it because I've heard some bad things about boss, but boss is amazing a serious competitor in the market now

I Got to say, i hear bad things about boss all the time, this is my first and is Great, for the price, may now have all the sound clarity of a Kicker, but it shakes two 15" MTX Rms 1000W (each) very hard, so for the difference of $200 you just cant go wrong

Ive owned this amp for about a week and it is a pretty good amp considering the cost. I actually brought the price down to $89.99 with "Low Price Guarantee" ...Oh and by the way im powering a 15" Kicker CVR. And will probably add a secondary sub pretty soon.

boss amp

January 26, 2012

I bought this having already owning a Power Acoustic ps2800 2-channel amp that is rated at 360 watts rms bridged. The boss nx18001 did not have as much power as the Power Acoustic. The rating of this amp should probably be around 250 watts rms if that. Don't waste your money like I did.
