Weather-resistant protection for music on the go

Conformal coating protects the internal circuits from water and dirt, so the show will always go on, even through the roughest conditions. The speaker output terminals feature plastic-covered plugs that provide further protection for those connections.

High-level inputs ease installation

The KAC-M3004 will accept a signal from just about any source, whether you're using RCA cables from an aftermarket receiver or speaker wires from a factory radio. When you use the speaker-level inputs, the amplifier will sense the signal and turn itself on, so you won't need to run a remote turn-on lead to your car stereo.

Features

Compact Amplifier: The Kenwood KAC-M3004 compact Class D 4-channel amplifier is designed to boost the output and clarity of your car stereo. 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-M3004 delivers 50 watts RMS x 4 channels at 4 ohms. It also gives you 75 watts RMS x 4 at 2 ohms, or 150 watts RMS x 2 channels at 4 ohms bridged.

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 four-channel amp is separated into two halves, labeled A and B. The A and B sections have independent crossovers. Each crossover can be set for high-pass or low-pass operation, or turned off for full range operation. Each crossover has a continuously variable crossover point (50 to 200 Hz) with a slope of 12dB/octave.

Mounting: The KAC-M3004 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 two pairs of RCA inputs for connecting stereo RCA patch cables 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 eight 16-gauge wires for connecting your speakers to the amp. You can connect the amplifier as a 4-channel system, a high-power 2-channel system, or a 2-channel + subwoofer system. Speaker wiring diagrams for each configuration are printed in the included Installation Guide.
