Product Research
Features
Power Ratings: The Sound Ordnance M350-1 is a Class D mono subwoofer amplifier with an RMS power rating of 290 watts into 4 ohms and 350 watts into 2 ohms.
Crossovers: The built-in low-pass crossover is continuously variable from 35 to 150 Hz and the slope is 12dB per octave. Because this is a subwoofer amp, the crossover is always engaged.
Sub Sonic Filter: The frequencies that cannot be reproduced by a subwoofer waste amplifier power and can cause damage to speakers. The sub sonic filter, variable from 15 Hz to 55 Hz, removes the signal below the setting to improve the performance of the speakers by eliminating distortion.
Bass Boost: The Bass EQ (bass boost) is continuously variable from 0 to +18 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.
Wired Remote: The included wired remote allows you to control the output level of the amplifier from the front of your vehicle. The wired remote can be mounted under your dash and the supplied 16' cable, with RJ-25 phone plugs at each end, connects the remote to the amplifier. The remote's dimensions are approximately:
- Width: 1-5/8" (2-5/8 including mounting flanges)
- Height: 7/8"
- Depth: 1-1/2" (2-1/8" including knob and cable)
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 also a set screw terminal that will accept up to 8-gauge wire. A 3mm Allen wrench is required to tighten/loosen the terminals (included).
Speaker Connections: The speaker output is a screw terminal that will accommodate up to 8-gauge wire.
Signal Inputs: The amplifier has a pair of stereo RCA inputs.
Remote: Connect the included wired remote to the RJ-25 port on the amplifier.

Amazing quality especially from the size. It really is smaller than you thin but it gets them subs going real well! I used this amp for 2 12s and they go real well with them and I'm really happy with the product. I would definitely recommend this to anyone looking to hook up a sub or two!
