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.

Amplifier Specifications

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
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.

500 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.
2 ohms
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
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%
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)
High-pass (HP)
Full (AP)
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.

Fixed (200 Hz)
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.
103 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.

Poor quality power.

February 2, 2013

I have had this amp for about 6 months now, i originally had it powering 2 10" MTX terminators at 150W RMS each, the amp did great with very little clipping with theese speakers, about 50% gain. I had since upgraded my subs to 2 10: Precision Power A.10 with the plan to upgrade my amplifier in the new year, i powered them up with this amp, wired at the same 2ohms as the MTX subs, with about 75% gain, sounded great for the first month, but into the second month the amp began to wear out and clipping occured at that gain level. I turned the gain down to 50% again and it kept clipping, well now i have $200 worth of subs with blown voice coils, I will not buy another boss product and will be ordering a Hifonics Brutus 1200.1d to replace this.

use this with low powered subs and you'll be fine. Definately not a quality amp though.

Amp is great, i use it to power 2 10" subs and it hits no problem, only downfall is the bass remote that comes with it. I am less than pleased with the quality of it, very cheap feeling plastic and when plugged in i lose about 20% volume.

I would recommend this amp! I installed it for a friend of mine in the navy, I had his car. I hooked it up to a 12" Kicker Comp Subwoofer. It pumped that sub without a problem, I was VERY impressed!!

Pros: Amp Quality, Reliability, Design, Power

Cons: The wheel to select how hard you want it to thump didnt do much.

September 21, 2012

Bought this amp to drive surrounding speakers in my van. I installed kicker 3.5 in and Orion 6x9 in each corner wired in parallel so this amp drives 8 sets of speakers at 2 ohm load. Sounds great, does not get too hot at full load, lots of headroom, no clipping or ignition noise. Nice - will buy again.

I have this amp pushing two Sony Xplod XS-GTX120LW 12" Subwoofers. They sound great and hit hard. I listen to mostly country so there's a lot of bass drum coming through. This amp does a great job and gets a little warm but I have it in the trunk where's there's a lot of air flow. I recommend this amp for anyone wanting a good price and good quality.

It's a good amp if you just want a little more bang out of your subs, but it's not gonna be heard from a distance.

If your looking for a bang don't get this but if your looking for better bass this would be a good buy considering the price. It's still pretty loud.

January 9, 2012

It's alright. Installation was easy. So far, (about 3 months later) it seems pretty durable, doesn't get hot. The bass knob is useless, i wouldn't recommend even installing it. Just use the sub controls on your deck. I have it pushing a kicker shallow mount 4 ohms rated at 400rms and this just doesn't push it like i feel it could be pushed. Will upgrade at a later date. Probly with a higher quality amp. Overall, you get what you pay for. Kudos to Sonic though. Their customer service, and shipping are first class. Have ordered several items and their shipping is always prompt.

I don't use the bass knob because it is so easy to setup and fine tune from the get go. I will recommend to anyone.

Not bad at all

December 27, 2011

Well, I am a sound quality guy, so everything in my vehicle is MB quart and focal etc. But I got this amp as a temp amp until I got my custom rack finished for the quarts. And I have to say, I was impressed. Especially for the stereotype that BOSS has as a reliable brand. So, it must be pointed out that I have owned many amplifiers over the years and aside from the black amplifiers that BOSS sells (which are actually not good at all), this one and the other silver models keep up well with everything else for the price. If you are looking for something simple, effective, and satisfactory, as a professional audio engineer, I must say, you should give this a try. I never had to replace it. Never had to push it hard. Never had problems with it at all. As long as you use it as intended, you should be fairly impressed with the quality of the cx models from BOSS. But stay away from any of the black amps they sell.

Slight Regret

September 19, 2011

I do have a slight regret about buying this amp. I used it in putting together a sound system for my sister and she doesn't know the difference between one amp and another, but she does notice when the sound stops, and that isn't good. This amp is putting out plenty of power for pushing a couple of 8's (which burned up because one of her friends thought she wasn't getting enough bass and turned up the amp during their break in period), and i even hooked up one of my old school Fosgate Punch 15s for temporary and it pushes it decent too. The main problem I see with it is that it gets too hot. It can go a good hour or so maxed out but eventually, it overheats. Of course this is a class AB amp so heat is not much of a surprise, but overheating should not happen, in my opinion. Great for short bursts, but for long runs, keep the gain down to about 1/4 and it will go much further. I would recommend getting a class d amp, as they put out good power and generally stay cooler, but for the money, I really can't gripe too much about this amp.

The Boss CX1100M is one of the best decisions I have ever made in choosing an amplifier. The wattage that it puts out is EXTREEM for the low price that it cost. I have my CX1100M hooked up in a 2003 Ford Mustang Convertable with two 10' Bazooka Liquid cool subs & it POUNDS. At first I thought I wasn't liking cause it wasn't putting out the Bass that I like & I wanted to go back using my 1200 watt Power Acoustik amp, but as soon as I changed my Head Unit I was very impressed with the decision that I had made, and I think you will be too.

Can't beat it bang for buck!

February 1, 2013

I have this amp powering 2 Infinity 1062s in a sealed box and they pound hard. I replaced an older Kenwood 6201 with this amp and there is a noticeable difference. The BOSS provides way more sound. So what if BOSS amps are rated in max power. Pay attention to the RMS rating and you won't be disappointed. Amp always runs cool. Match it with the right subs and you've got the best bang for the buck mono amp available.

Its Okay

January 17, 2012

I have owned this amp for about 6 months now, and it just cut out. I had my sub wired for two ohms which the sub can handle. It couldnt and would overheat. I rewired my sub to 4 ohms and now it sounds better. For the price its an okay amp. But for a little bit more you should probably just go with something a little more reliable.

This amp powers 2 1000 watt subs with no problem. The rms response is wonderful for the price. The amp looks great and takes a beating, ive gotten it wet stacked stuff on top of it and it still works great. Don't pass it up just because you dont know the name.

Muy bueno lo recomiendo

I was looking for good bass in my minivan and it turned out perfect. I can feel the vibration in the distance. Set in a box with 2 subs and they sound the best at a reasonable price.

The only reason people don\'t like this is because they have it hooked up to subs, its made for speakers! Class D amps are made for subs; this is GREAT for the price love it!

Nice Amp

December 8, 2010

I bought this amp about a year ago along with a 1200W Kenwood 12 " sub and ported box and it preforms. This amp give my sub a nice boom, yet still a good kick of quality for those audio enthusiasts like me. A very nice amp for an average sub, just cant shake your fellow drivers windows. Gets a little warm when you're booming loud, but other than that, a great starter amp.

Would a Boss CX1100M work well with a set of 2 12 inch Kenwood subwoofers?
A shopper on Jun 15, 2015
Boss CX1100M

Best Answer: Hello,

For future inquiries - even though you linked it - please provide MODEL NUMBERS, not descriptions (i.e. "2 12 inch Kenwood subwoofers" . Some won't see the subs that you are referring to , so you can imagine what they might be thinking when you ask a "vague" question =] .

As far as your question goes: The figures match perfectly, 500w RMS @ 2ohms, but the performance might not. The BOSS line is fairly entry level, and as Bryan explained may be underpowered compared to what it claims.

As a reference, the matching amplifier is the Kenwood KAC-5001PS.
