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.
250 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.
Riot (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.

AB
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.

1100 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
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.
0.01%
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 - 160 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.
102 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.
30A 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.

September 7, 2014

Does a great job of powering my Rockford Fosgate 10". Doesn't feel cheap at all. Performs like it should. Consistent power and looks great! Definitely a perfect buy for a couple of 12s or 10s. Even better if your just doing a single 10/12!

Boss 1100w amp - Great amp

December 28, 2014

Great little amps. I was absolutely blown away by the power that is produced from this little amp. I had another 1100w amp that did not produce nearly as much sound. Except that I had to return the first unit I had after about 1.5 months, it great. I have had the new unit for over three months and it works great. Great amp for the price.

would this be a good amp to match a pair of Kicker 10C124's?
Hunter B on Aug 20, 2014
Best Answer: Hello Hunter,

We are not confident in this amp being able to power your Two Kicker C124 (10C124). The manufacture fails to give us a Proper RMS Rating at 2ohms - which is what a pair of Kicker C124 (10C124) will be wired to in Parallel - so we will be hard pressed in suggesting this amp. We suggest one of the following instead:

Good:

What would be a good cheap 12" 2 ohm subwoofer to run with this amp?
Kadin P on Nov 26, 2014
Best Answer: This is a 4 ohm amp. You need to find a 2 ohm amp to power your 2 ohm sub. You should also try to find an amp with a similar rms power rating (not peak power), to run your sub. If you choose too weak of an amp, you are actually more likely to fry your sub than if you use a more powerful one. I recommend staying within a 100w range of your sub. Remember that peak power really means nothing; it is just a marketing ploy. The important figure to pay attention to is rms power rating.

Hi, I am considering purchasing a JL Audio CS110-WXv2 with RMS of 75-200. I don't plan on cranking up my system to absurd levels. Would this amp be sufficient? In addition, I just had my infinity basslink crap out on me. Normal from what I read after about 2 years of normal use. The wiring, power, ground and REM are already in the back of the trunk. I assume those wires would simply up to the new amp? I assume the universal interface connectors will not be needed if I go with the JBL sub. Would the CS110-WXv2 be a good choice for general music listening. A little of everything. Also would be going into a subaru 2000 2.5rs sedan in the trunk. Pretty small car. Thanks

Best Answer: Hello,

'Sufficient', yes; But nothing Boss makes will match the Quality of a JL Audio Product, they are just far too apart in overall performance and application. We often recommend no less than the Kenwood KAC-5001PS . Assuming the Basslink used At Least 10gauge (preferably 8gauge) power/ground, then it can be re-used.

Would this work be a amp for a single Kenwood KFC-W12PS Subwoofer in a Toyota Corlola trunk?
A shopper on Dec 12, 2014
Best Answer: Yes. That Kenwood and this amp both have the same RMS at 250 watt and peak close to the same with the sub at 1,000 watt and the amp at 1,100 watt. Just make sure you don't crank the bass boost all the way up or you could damage the subwoofer. Other than that it looks like these two were made to be wired together.

is this amp good with kicker 40tcws102 10inch 600watts sub woofer?
A shopper on May 23, 2015
Best Answer: Hello,

The 40TCWS102 is asking for 300w RMS (600 refers to the Peak power, which is a fairly useless figure when determining a match) . Further more it is asking for those 300W RMS @2ohms, making this amp Not a proper match. To reiterate, you seek an amp that provides 300w RMS @2ohms. The intended match is the Kicker CX300.1.

Please do some homework on WIRING SUBWOOFERS, it will make my response easier to understand. I've also added a few links to help.

ONE Subwoofer on ONE amp will work because a DUAL-2ohm subwoofer can be wired in SERIES to a 4ohm load.

Would you recommend this to power a single Infinity Reference 12" 1260w or 1262w?
Aaron H on Aug 23, 2014
Best Answer: Hello Aaron,

We would Not recommend this amp. This is because it RMS rating at 4 ohms is only 250 watts x 1. Which means you would Have to go with the Infinity Reference 1260W, but then it will be underpowered by 50w RMS. In this power range you definitely want to squeeze out as much as possible. Here are a few better recommendations, that will require the Infinity Reference 1260W;
