Build your car audio system on a firm foundation of power. Kenwood amplifiers established their reputation with their rugged, no-nonsense reliability and superior sound quality. Heavy-duty internal components provide an abundant source of clean, crisp sound at a great price.

Your subwoofer needs a steady dose of power to drive it — the KAC-6401D mono amp delivers up to 300 watts RMS. A built-in low-pass filter adjusts amplifier output so you'll get the best sound possible from your subwoofer/box combo. Efficient MOSFET power supplies keep the juice flowing steadily, while the aluminum heatsink lets the amp stay cool, even when you're pushing it hard. Convenient speaker-level inputs let you hook a KAC-6104D up to your factory stereo.

CEA-2006 Compliant: CEA-2006 is a new 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 at a frequency range of 20 Hz to 200 Hz 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. The Kenwood KAC-6104D under CEA-2006 regulations is rated at 200 Watts RMS x 1 channel with a 75 dBA signal to noise ratio.

Mono-Power Amp Design: The Kenwood KAC-6104D is designed with specific features to power your subwoofers with a frequency range between 20-200 Hz. This amplifier is not designed to power a full-range speaker.

2-Ohm Stable: The Kenwood mono-amplifier is capable of handling load impedances down to 2-ohms. The amplifier is rated at 300 Watts RMS x 1 channel in 2 ohms at 100Hz with 1.0% THD.

Class D Amplifier Design: The KAC-6104D is a Class D mono amplifier, which uses digital switching to amplify audio signals. This design results in high efficiency and less heat.

MOS-FET Switching Power Supply: The amplifier utilizes a MOS-FET switching power supply providing thermal stability and efficient switching speeds guaranteeing performance and dependability.

Parallel Connection: The amplifier is equipped with two pair of speaker terminals for an easy parallel subwoofer connection.

Low-Pass Filter: The KAC-6104D has a built-in 12dB/octave low-pass filter that is continuously variable from 50Hz to 200Hz.

Bass Expander: Turn on the Bass Expander for a more dynamic bass output at higher volume.

Line Level Inputs: The RCA type line-level inputs have a gain (Input Sensitivity) control adjustable from 200mV to 5.0 Volts.

Speaker Level Input: The KAC-6104D comes with a speaker level input harness. This feature makes it easier to add an amplifier to a factory radio or to a receiver with no preamp outputs.

Power Indicator: When the amplifier is turned on, the power indicator lights up. This indicator turns off with the amplifier and will turn off if the amplifier goes into protect mode.

Protection circuitry: The amplifier features protection circuits that will turn the amp off in case of the following events to protect the amplifier and your speakers:

  • Speaker wire short-circuits
  • Speaker output contacts ground
  • Unit malfunctions and DC is sent to speaker output
  • Internal temperature is too high
  • Loss of ground of head unit or amp
