Kenwood Kac-M8005 5-Channel Power Amplifier
Compact mono subwoofer amplifier 300 watts RMS x 1 at 2 ohms
Kenwood's KAC-M3001 compact mono subwoofer amplifier will power the bass in your vehicle with up to 300 watts RMS. That's enough to hear the bass clearly above the noise of the road, trail, or waterway as you travel along. This little powerhouse will fit almost anywhere, including a storage compartment on a boat, motorcycle, or ATV, so you can put great bass in whatever vehicle you wish. 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 subwoofer output terminal features a plastic-covered plug that provides further protection for the connection. High-level inputs ease installation
The KAC-M3001 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. Confused about impedance?

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.
Kenwood KAC-M8005 - Power your whole system
Kenwood's KAC-M8005 5-channel amplifier can power your entire sound system, sending out 50 watts RMS each to your four full-range speakers, and up to 500 watts RMS to your sub. Want to run a set of high-performance components plus a subwoofer? You can set the KAC-M8005 to 3-channel mode, driving your components with 150 watts RMS per side while still sending 500 watts to your sub.
CEA-2006 is a system of testing and measurement methods for mobile audio amplifiers. This voluntary standard advocates a uniform method for determining an amplifier's RMS power output and signal-to-noise ratio. The criteria for measuring power uses a DC input voltage of 14.4 volts and the RMS power output is measured into a 4-ohm load, with 1% or less Total Harmonic Distortion (THD) plus noise, and over a frequency range of 20 Hz to 20 kHz, when applicable. Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. CEA-2006 allows consumers to compare car amplifiers and receivers on an equal basis. Using CEA-2006 criteria, the Kenwood KAC-M8005 is rated at 50 Watts RMS x 4 channels + 300 watts RMS x 1, with an 80 dBA signal-to-noise ratio.
Class D Amplifier Design
The amplifier design is Class D, which uses digital switching power supplies. The result is the amplifier runs more efficiently, generating less heat than Class AB amps. The Class D design also allows the amplifier to be built on a small chassis, and installed where space is limited.
- Line In: The KAC-M8005 has three pairs of RCA inputs for connecting the amp to the source unit via RCA cables. The amp will accept a low-level signal between 200mV and 5V. It will also accept a speaker level input between 4V and 12V. For a speaker level input, the source unit's speaker wires will need to be spliced onto RCA plugs, or use a third-party speaker-to-RCA adapter.
- Power/Ground/Remote Turn-on: The amplifier has screw-down terminals for the power, ground, and remote turn-on, and will accommodate spade connectors. The power and ground terminals are 0.55" wide, while the remote turn-on terminal is 0.33" wide.
- Speaker Output: Five pairs of screw terminals are provided for connecting the speakers. The terminals are 0.33" wide, and accommodate spade connectors. The amplifier is designed for a 4Ω load on the A and B channels, but can can handle a load impedance of 2Ω to 8Ω. The A and B channels can be bridged to a 4Ω-8Ω load. The Sub channel is designed for a 2Ω load or higher.
