Features
Compact Amplifier: The Kenwood KAC-M3001 compact Class D mono block amplifier is designed to drive a subwoofer (or two). The amp features a conformal coating on the circuit board to protect it from moisture. This allows you to use the amp for motorcycles, marine applications, or on All-Terrain Vehicles (ATVs). The KAC-M3001 delivers 200 watts RMS x 1 channel at 4 ohms. It also gives you 300 watts RMS x 1 at 2 ohms.
Protection Circuitry: The amplifier features protection circuitry for thermal overload, DC offset, and short circuits. The amp stops operating when it goes into protection mode. (There are no LED indicators.)
Signal-sensing Turn-on: When the amplifier is connected to a factory head unit, or an aftermarket unit without preamp outputs, you can splice the head unit's speaker wires to a speaker-to-male RCA adapter. In this case, the amplifier's Signal-sensing Turn-on feature will turn on the amp when a signal is detected on the input. This eliminates the need to connect a turn-on lead to the amp's Power Control (blue) wire.
Crossover: The amp has a low-pass crossover to filter out the high frequencies that a subwoofer is unable to reproduce. The crossover has a continuously variable crossover point (50 to 200 Hz) with a slope of 24dB/octave. The crossover cannot be turned off.
Mounting: The KAC-M3001 can be mounted onto an installation board (5/8" thick or more) using the supplied M4 x 16mm self-tapping screws. Two 13.5" plastic wire ties are included for securing the amplifier to a 2x4 board or other narrow item.
Connections
Power/Power Control Connections: The power, ground, and power control connections are 0.35" wide screw terminals. A Phillips-head or flat blade screw driver (not supplied) is required to tighten/loosen the terminals. Spade connectors or ring terminals are recommended. A minimum 10-gauge wire is required for power and ground.
Power Control: The Power Control wire should be connected to the head unit's remote turn-on lead when an aftermarket unit is used. This wire does not need to be connected if you're using speaker level inputs. The Signal-sensing Turn-on feature will turn on the amplifier when an input signal is detected.
Line-Level Inputs: The amplifier is equipped with a pair of RCA inputs for connecting a stereo RCA patch cable from the head unit to the amp. If using a factory head unit, or a unit without preamp outputs, you can splice the speaker wires to an RCA plug, maintaining the same polarity.
Speaker Outputs: The included speaker output harness has four 16-gauge wires for connecting your speakers to the amp. The two positive and two negative wires are each soldered together to produce a single positive and a single negative output. You can connect a single 4-ohm or 2-ohm sub directly to the amplifier. Two 4-ohm subs wired in parallel or two 2-ohm subs wired in series can also be connected. Speaker wiring diagrams for each configuration are printed in the included Installation Guide.

Installed this little amp to power a 2 ohm 10 inch Clarion sub in my boat. Plenty of power in a compact package. Easy to setup, easy to tune. Crutchfield shipping was super fast as well!
