Features

Power Ratings: The Sound Ordnance M100-2 is a 2-channel Class D amplifier with an RMS power rating of 110 watts per channel into 4 ohms, and 140 watts per channel into 2 ohms. The amp can also be bridged into a 4-ohm load for a power rating of 200 watts (x 1). Power ratings are measured with an input power of 13.6 volts.

Crossovers: The built-in crossover can be set to high-pass, low-pass, or full range. The crossover point is continuously variable from 50 to 750 Hz and the slope is 12dB per octave.

Bass Boost: The Bass EQ (bass boost) is continuously variable from 0 to +12 dB and is centered at 45 Hz.

LED Indicators: There are two LED indicators: a green LED that illuminates when the amp is powered on, and a red LED that illuminates when the amplifier is in protect mode due to overheating or a short circuit in the speaker wire.

Fan Cooled: A thermally-activated fan on the bottom of the amp helps cool the internal components.

Connections

Power Connections: The power and ground connections are set screw terminals that will accommodate up to 8-gauge wire. (An 8-gauge amplifier wiring kit is recommended.) The remote turn-on terminal is a set screw terminal that will also accept up to 8-gauge wire. A 3mm Allen wrench is required to tighten/loosen the terminals (included).

Speaker Connections: The speaker terminal can be removed from the amp, which makes connecting the speaker wires easier. The terminal is mounted to the chassis of the amp with two screws. Bare speaker wire, up to 12-gauge, is held in place by screw-clamps on the terminal. A flat blade screwdriver (not supplied) is required to tighten/loosen the screw-clamps.

Signal Inputs: The amplifier has a pair of stereo RCA inputs.

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
Felt like it would give me the best sound with the 5.25 Polk speakers. It also has a small foot print to fit under the front fairing of my 2007 HD Street Glide. A plus, is that if I add front lower fairing speakers and bridge the channels, I'm still getting 70W to all 4 speakers. So it gives me room to grow. [ Shawn  Apr 04, 2020 ]
A
Sound Ordnance is very good quality, very well built and has great sound quality especially for the price. I have a SO B-8PTD 8 inch powered sub that is about 6 years old now and has never had any problems at all, still works great like the day I bought it. [ James  Oct 15, 2019 ]

A
It has the best price and perfect reviews. I am pairing this with the Kicker 40CSS684 set of 6x8 speakers, each rated at 75w RMS. Using crutchfield's advised method of choosing an amp (taking the RMS of speaker x 0.75 x 1.5) that comes out to an amp that can push out over 85 watts. Kickers are also able to handle quite a bit more than advertised, so this 110 watt amp is absolutely perfect to use with a pair of 75w RMS speakers. [ Billy  Sep 13, 2016 ]
A
best amp for the money and small footprint [ BRYAN  Aug 22, 2016 ]

Read an article on here about a guy with a convertible looking for a decent amp. I haven't bought an amp since 1977,and funny enough it was for a corvair as well., Jenny seems quite knowledgeable with setting up systems. I haven't bought all she suggested, yet..... budget [ Kurt  Jul 22, 2016 ]

Q
Can I use this to power two pairs of speakers (4 total)? One pair of Sound Ordnance 6 1/2 P65CB component speakers on the front doors and another pair in the back, to be exact.

I have been running a pair of 6x9s off of this and I would think it'll run 4 6 1/2. compare the RMS rating though. ideally the total of the speakers should be lower than the output of the amp.
[ Ethan Wendell  Mar 29, 2018 ]
A
Good question. I believe so. My application was a bit different. I used this amp in my z3 for the subwoofer. I bridged the amp to provide the power. I used another compact amp (4 channel) to provide power a set of component speaker in the footwell & door(6 1/2) and a set of 4in speakers behind the seats. This part of my install seems closer to your scenario. I used 2 channels to power the component speakers. The lead from the amp went to the crossovers first and the crossovers distributed the power. The remaining two channels powered the rear speakers. I used the gain knobs to set the balance and power levels. Hope this helps.

Yes you can use this amp..don't be fooled by the little size of it....it packs a punch....I have the same one,,and I am impressed
[ Pete  Jul 20, 2017 ]

Hi, I have a 2001 BMW z3 roadster and use this amp to power the subwoofer only. I used the Alpine KTP-445U Power Pack to power the front component speakers w/ crossovers and 4inch rear speakers. A Kenwood head unit was also used. This works for my application. Hope this helps.
[ jason  Jul 20, 2017 ]
A
Absolutely, I have this running my Polk audio components and it is more than enough power, reliable clean power.
[ David  Jul 20, 2017 ]
Q
I'm thinking of installing this amp in my bike to power the 2 front speakers, any one know if this will draw to much power from my electrical system or should it work?
[ jim  Jun 29, 2017 ]

I think that this amp will work fine for you. It does not draw too much power . If you use the right installation kit with the right gauge wire, you should be just fine.
