Product Research


Class D Amplifier Design: The KAC-9105D is a Class D mono-block amplifier, which uses digital switching to amplify audio signals. This design results in high efficiency and less heat.

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

Mono-Power Amp Design: The Kenwood KAC-9105D is designed with specific features to power your subwoofers with a frequency range between 10-200 Hz. The amplifier can handle impedance loads down to 1-ohm.

CEA 2006 Compliant: The KAC-9105Ds power ratings are measured according to the strict standards dictated by the Consumer Electronics Association (CEA). These standards allow you to accurately compare the rated power output of all CEA 2006-compliant amplifiers, even if they come from different brands. Manufacturers who adhere to the standards can display the CEA 2006 logo on their products and packaging. Amplifier Power Ratings:

Mono-Channel (4-ohm): 500 watts x 1 channel RMS (20-200 Hz, 1% THD)
Mono-Channel (2-ohm): 900 watts x 1 channel RMS (100 Hz, 1% THD)
Mono-Channel (1-ohm): over 900 watts x 1 channel
Peak Power: 1800 watts x 1 channel
Note: This amplifier is not designed to power a full-range speaker.
Cast Aluminum Heat Sink: The Kenwood KAC-9105D utilizes a cast aluminum heat sink design to ensure that the amplifier stays at its optimal temperature.

Fan Cooled: There are two fans and two vents located on the back side of the amplifier to help dissipate heat and ensure cool, reliable operation. Make sure not to block these vents or fans when you install the amplifier.

Protection circuitry: The amplifier features protection circuits that will turn the amp off in case of the following events:

Speaker output contacts ground
Speaker wire short-circuits
Unit malfunctions and DC is sent to speaker output
Aluminum Cover Plate: The amplifiers controls and connections are hidden under a removable extruded aluminum cover plate. The cover plate provides a professional looking installing while helping to protect the amplifiers connections and control settings. The cover is held in place by two hex head screws. An allen-wrench is supplied to remove the cover.

Blue/Red Illumination: The Kenwood Mono-Channel amplifier features a blue and red LED illumination when the amplifier is turned on. When the power is turned on to the amplifier, the Power indicator will light up red. This indicator will turn off with the amplifier and will turn off if the amplifier goes into protect mode. The amplifier also features a Blue LED lamp on the top of the amplifier which illuminates when the amplifier is on.

Signal-sensing Turn-On Circuitry: When the speaker-level input is used, it is not necessary to connect the power control wire (turn-on lead). The amplifier senses the signal from the speaker-level input and turns the amplifier power on automatically. Shortly after no signal is detected, the amplifier will automatically shut itself off.


Gain: To accommodate the varying range of signal levels coming from todays factory and aftermarket radios, the Kenwood KAC-9105D features an adjustable, independent gain control (0.2-5.0V). This means that no matter what kind of radio is connected to this amplifier, the appropriate gain control adjustment can be made to ensure loud, clear, distortion-free music.

Low-Pass Filter: The KAC-9105D has a built-in 24dB/octave low-pass filter that is continuously variable from 50Hz to 200Hz.

Bass Boost: The bass boost is adjustable from 0-18dB at 40Hz.

Phase Switch: This amplifier is equipped with a 2-way phase switch. You can choose 0° (normal phase) or 180° (reverse phase), whichever position results in stronger performance for the subwoofer.

Infrasonic Filter: This amp features an 18dB/octave Infrasonic Filter. Ultra-low frequencies that cannot be reproduced by a subwoofer do not become sound but become unnecessary oscillations, which affect sound by causing distortion. These frequencies also waste amplifier power and can cause damage to speakers. Setting the Infrasonic filter switch to 15Hz or 25Hz cuts the frequencies below the respective frequency to improve the reproduction performance of the speakers by eliminating harmful distortion.


Power Connections: The power and ground connections are 0.5625 wide screw terminals that will accommodate up to 4-gauge wire. The remote turn-on terminal is 0.3125 wide and will accept up to 8-gauge wire. A Phillips-head or flat blade screw driver (not supplied) is required to tighten/loosen the terminals. Spade connectors are recommended for the power, ground, and remote wires.

Speaker Outputs: The Kenwood KAC-9105D is equipped with two pairs of gold-plated speaker terminals for an easy parallel subwoofer connection. All four speaker terminals are 0.3125 wide screw terminals and will accommodate up to 8-gauge wire. A Phillips-head or flat blade screw driver (not supplied) is required to tighten/loosen the terminals. Spade connectors are recommended for the speaker wires.

Line Level Input: The mono-channel amplifier is equipped with a single pair of gold-plated RCA line level inputs.

Speaker Level Input: The KAC-9105D comes with a two channel speaker level input harness. Once you splice the speaker wires from the receiver to the harness, you have plug-in convenience to the amplifier. This feature makes it easier to add an amplifier to a factory radio or to a receiver with no preamp outputs. The maximum power output from the source receiver can be no more than 40 watts.

Line Level Output: The amplifier has a pair of gold-plated RCA line level outputs for feeding a full-range stereo signal to another amplifier. It is the same signal that is input through the line inputs. The amplifiers crossovers have no effect on the line level output signal.

Fuses: The KAC-9105D is equipped with three 30 amp ATC blade fuses.
