Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Power Ratings: The Sound Ordnance M-2100 is a two-channel
Class AB amplifier with an RMS power rating of 75 watts per channel into 4
ohms, and 100 watts per channel into 2 ohms. The amp can also be bridged into a

input power of 14.4 volts.
Crossovers: The M-2100 is equipped with both high-pass and
low-pass crossovers. You can set the low-pass cutoff frequency between 50Hz and
