Power Ratings: The Sound Ordnance M-1500 is a mono-block Class AB amplifier with an RMS power rating of 300 watts per channel into 4 ohms, and 500 watts per channel into 2 ohms.Power ratings are measured with an input power of 14.4 volts.
Crossovers: The M-1500 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. Boost is continuously variable from 0dB to +12dB and centered at 45 Hz.
LED Indicators: The M-1500 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 speaker wire.
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-1500 are removable with a 3mm Allen wrench (not supplied) to make it easier to attach the power and speaker wires.
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 the terminals.
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-1500 features two 30-amp ATC blade fuses.
