Inputs and Outputs
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
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
- Internal temperature is too high
- Loss of ground of head unit or amp
Left Side of the Amplifier: All of the amplifier's controls
are found on the left side.
- Bass Expander: on/off
- Low Pass Frequency: 50-200
- Input Sensitivity: 200mV-5V
Inputs and Outputs
Left Side of the Amplifier:
- Line In: one pair of RCA

input for use with the included speaker level input
Right Side of the Amplifier:
- Fuse: One 30 amp ATO fuse
- Power: screw terminal
- Ground: screw terminal
- Remote Turn-on: screw
terminal (0.34" wide)
- Speaker Outputs: two pair
of terminals (0.34" wide), the two outputs
are internally wired in parallel
