View larger Class A/B Topology A class A/B amplifier uses two groups of transistors and it is generally considered to be the best compromise of the two classes put together. A pure class ‘A’ amplifier typically has an enormous amount of current flowing through its output transistors with no audio signal. A pure class ‘B’ amplifier has no current flowing through its outputs with no audio signal. This eliminates virtually all of the crossover distortion that’s possible with class ‘B’ amplifiers. A class A/B amplifier is much more efficient than a class ‘A’ but without the possible distortion of a class ‘B’.

    Optimistic power claims, August 4, 2012

    I’m an electronics engineer so I care about specifications. This amplifier is a low cost item which offers reasonable value, but I wish they would be more honest with their claims.

    My measurements show 21.5V rms continuous into 4 ohms at the onset of clipping with a 14.12V supply. This is 115W rms.
    With no load it gives 23.9V with 14.12V supply. This corresponds to 142W rms peak.

    So, essentially it is a 100-150W amp (4 ohms), or at best 200-300W (probably less) into 2 ohms. The claims of 250W into 4 ohms or 1100W into 2 ohms are at best ridiculously optimistic.

    I would suggest that it is worth paying a bit more to get something better.

    Sorry folks…

    But there are a couple of myths, being two pieces of (…dare I say it?) outright misinformation that have become attached to this compact masterpiece, …even though I’m sure both of them were offered with the best of intentions.

    As for me, I thought I’d wait until I’d driven it hard and bounced it around the Aussie Outback for a couple of months before any attempt at reviewing it.

    A little background: I’m an Audio Director/Sound Supervisor in my fifth decade of ongoing work in this field, most of it live (or “as live”) and on location.

    My Boss Audio R1100M is used to drive either full-spectrum sub plus line array or horn plus ported-woofer long range speakers (a choice dependent on the vagaries of weather and/or crowd numbers) at impedances from four to sixteen ohms, …the only constant factor being the need to rely exclusively on DC vehicle power.

    The verdict: …five stars. No doubt whatsoever.

    The Boss Audio R1100M delivers far more than something that’s roughly the price of a case of beer should ever be able to do.

    (What a crying shame that its excellent internal fan-cooling arrangements don’t actually extend to chilling beer. Now that WOULD be a world-beater…)

    To those well-intentioned myths:

    First, “The Remote Subwoofer Level Control doesn’t work.”

    Not when the amp’s switched to “Full Range” it doesn’t.

    When it’s in “Full Range”, it isn’t expecting to be driving just a subwoofer, is it? Switched to “Low Pass” (i.e. subwoofer) mode, the remote control works a treat.

    Second, “It’s under-powered.”

    Hang on a cotton-picking second, did you honestly expect to have mountain-moving power for the price of a case of cold ones?

    Now look at it’s main fuse. It’s 30 amps. That’s your lot, any more and it all goes dark and quiet until you replace the fuse.

    Time for some basic arithmetic, 12 x 30 = 360. That’s 360 watts of total power going in.

    Wait a second, my alternator kicks out a gargantuan 14.4 volts! Whoopee! Hurrah! Huzzah! Hallelujah! I’ve now got an earth-shattering 432 watts at my command!

    …Uuh, …um, …well, …er, …I WOULD have if everything inside the immaculately designed Boss-Box yielded 100% efficiency.

    Sadly, 100% efficiency from ANY power system is the stuff of Nobel Prizes and/or science fiction.

    (Trust me when I say that you won’t ever again need to consult anyone’s review of anything after YOU’VE developed a power system that’s 100% efficient.)

    Meanwhile, back in the “Real World”, guess what?

    With power being wasted to generate heat, run cooling fans and the losses inherent in each and every electronic step taken, the BEST amplifiers are around 25% efficient.

    25% of 432 watts?

    That would be 108, just a tad LESS than I (and others) have observed to be the continuous power actually (and reliably) delivered from this tiny Boss-Box into 4 ohms.

    The controls all do exactly what they’re meant to do. The sound is clean, gutsy and free of artefacts, so, by way of a conclusion, here’s the outcome of some OTHER basic arithmetic I did prior to buying it…

    I can’t buy an aluminium housing of comparable ruggedness for the price of this entire amplifier.

    what i wanted, September 14, 2014

    This review is from: Boss Audio Riot Monoblock Class A/B Amplifier R1100M, 1100-Watts, Black (Electronics)
    this amp works great for what I needed. I have a 200w RMS RE Audio RFX 10″ sub and I wanted this to complement my stock sound system.

    I was looking for an amp with the “high level” inputs. so i could run speaker wire from my radio straight to my amp without a line level converter. you will get better sound this way by losing less signal. you must use well shielded pure copper speaker wire, because its easier to pick up interference this way. I have not had any interference issues. I used C&E 14AWG OFC speaker wire, with a Stinger 8 gauge OFC wire kit. I have the speaker wire ran right next to the power cable (this can cause alternator wine in cheaper cables) your system will only be as good as the wires you use. I spent more on the wires then I did for any other part of this build.

    I wanted to keep the budget below $250 for everything. here is my parts list:
    Boss Audio R1100M… $55
    RE Audio RFX 10″… $65
    Stinger 8 Gauge Amplifier Wiring Kit… $35
    Stinger 8 Gauge Black Ground Wire 10ft… $12 (I needed extra)
    C&E 100ft 14AWG Oxygen Free Copper speaker cable… $30
    BOSS Audio CPBL2… $32 (did not use)
    ASC Single 10″ Subwoofer Sealed Hatchback Enclosure… $30

    Total: about $260

    I know that the Boss amps are over rated, just like I know my RE sub is under rated. if I had to guess I would say this amp is putting out something like 300w RMS at 2ohms. and the RE is probably close to the same. for the price of these Boss amps you cant beat them. I got this set up for sound quality because I had heard good things about RE Audio’s. if needed this set up will shake your mirrors. I run the amp at 1/4 gain and it compliments the stock system in my Mazda 3 hatchback perfect with taking up very little space. if you have speakers at the 300w RMS range. this is a great amp on a budget.
