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-1350 is a mono-block
Class AB amplifier with an RMS power rating of 210 watts per channel into 4
ohms, and 350 watts per channel into 2 ohms.Power ratings are measured with an
input power of 14.4 volts.
Crossovers: The M-1350 is equipped with a low-pass crossover
and a subsonic filter. You can set the low-pass cutoff frequency between 40Hz
and 300Hz. The subsonic filter, designed to block ultra low frequencies that can
damage speakers and rob amplifier power, is variable between 10Hz and 40Hz. The
crossovers have a 12dB per octave slope, and cannot be turned off.
Bass Boost: The amplifier has a rotary bass boost control,
which is continuously variable from 0dB to +12dB at 45 Hz.
LED Indicators: The M-1350 features 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
Remote Bass Control: The amplifier comes with a remote bass
control module to allow you to adjust the volume of the amp from the front of
the vehicle. The module has a rotary volume control knob, and an LED to indicate
when the amplifier is turned on. The module is designed to mount under the dash,
and comes with 16-1/2 feet of cable.
Removable End Caps: The end caps on the M-1350 are removable
with a 3mm Allen wrench (not supplied) to make it easier to attach the power and
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 Phillips-head screwdriver (not supplied) is required to tighten/loosen
Speaker Connections: The
speaker connections are set screw terminals that will accommodate up to 8-gauge wire.
Even though this is a mono amplifier, there are two sets of speaker outputs.
The terminals are wired in parallel internally, allowing you to connect two
4-ohm speakers to separate terminals. A Phillips-head screwdriver (not supplied) is required to tighten/loosen the terminals.
RCA Inputs and Outputs: The amplifier features a pair of
stereo RCA inputs for connecting your head unit. There is also a pair of stereo
RCA outputs for feeding the preamp signal to another amplifier, if needed.
Fuses: The M-1350 features two 25-amp ATC blade fuses.
