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.

1400 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.
Armor (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.

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.

2500 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.

1400 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.
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
2 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.
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.
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.
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.

40 - 130 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.
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 - 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.
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).
Fuse Rating
The amperage and the number of fuse(s) an amp requires.
30A 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.

best bang for the buck

December 17, 2014

Bought this to hookup to a set of 2 10 inch cerwin Vega heds 800 watt max not expecting a whole lot but I have always used boss so I figured I'll give it a try. Great clean sound and punches good on 2 tens wish I had more sub's now! The only complain is that it doesn't have a bass boost option like the riot series does but at 2500 watts who needs that option anyways. Sonicelectronix was fast accurate and packed sufficiently as not to damage the product service: 10/10 product: 8.5/10

Overated too the hilt !!!

November 1, 2012

The others that have reviewed this amp must be running it at 2 ohms.I'm running two 10" cvrs at 4 ohms requiring 800watts rms.I'd estimated it's output to be more like 700rms at 4 ohms not the 1400rms that Boss is claiming.Sound at low levels is not good and gets worse at higher levels,May sound better at 2 ohms but don't bother if you are plannig to run it at 4.I need my Rockford back.

Good for the price

September 18, 2012

I ordered this amp after having the boss ar1500m for only one day. It makes my two kicker CVR 12' slam even with the bass turned all the way down. I would suggest this amp for anyone looking for a good amp on a budget. It says that the amp is 2500 Watts at 2ohms but its more like 1500 Watts. Also I don't know that the amp always runs hot but it usually is hot but it might be because I live in a place where it is hot all the time. And yes I would recommend it to a friend. Another bonus is that it comes with a bass knob witch is a $20 value its self

A lot of power

September 7, 2015

I have had it in my truck for a month and I've repeatedly scared people with it because they weren't expecting how good it was. I've puahed it hard seeing if it'd blow from overpowering but it's lasted. There's only two things I don't like about it, first: it doesn't get the higher up notes, and second: I'm not sure if it's because of the enclosure and how I have it facing, but it isn't as loud as I'd like, but for the price it's great. I plan on doing a build with 4 in the back of my truck.

Amp box says 1400 Watts MAX at 4 ohms not RMS

April 12, 2014

Either both websites, this one and Boss have made an error on there website or Boss made it on the box. Although I guess it is hard to believe you would get 1400 Watts RMS at only $80. Should of seen that one coming... Dont know if my ride can handle any more watts without upgrading the charging system anyways especially when it already has an amp powering the (4) 6x9's.

This amp is one of the best I've ever installed or heard. I have it powering a 12 inch sub and it's plain perfect sounding. The bass knob allows me to enjoy lower bass songs or crank it up for hard hitting songs. All in all its plenty of you just have one 12 inch subwoofer.

Makes Them Hit Hard

July 26, 2012

Buy this about 2 two months ago. Treated myself with wifes ok to spend $. great price, better sound I have two 12" kenwood subs in sealed box 800 watts each. Makes them hit harter than the two 12 kickers I had with a apline v power amp. Way louder. Does get a little hot, but I have had jbl amps that shut off a less power than the boss amp. The brand Boss is not given the props it should get. I say there coming up. Great amp!

Will this subwoofer work at 2 ohms?
A shopper on Jan 27, 2015
Best Answer: You can run that amp on 2 ohms. But hifonics or mbquart are better amps for the money. Boss amps are highly over rated and they don't put anywhere near rated power it might say 1400 rms watts but in reality when you test it you might be only getting 600 rms. Hifonics is the best bang for the buck
