Safety precautions
To prevent injury or fire, take the following
precautions:
· When extending the ignition, battery, or
ground wires, make sure to use automotive-
grade wires or other wires with a 8mm2
(AWG8) or more to prevent wire deterioration
and damage to the wire coating.
· To prevent a short circuit, never put or leave
any metallic objects (such as coins or metal
tools) inside the unit.
· If the unit starts to emit smoke or strange
smells, turn off the power immediately and
consult your Kenwood dealer.
· Do not touch the unit during use because the
surface of the unit becomes hot and may
cause burns if touched.
To prevent damage to the machine, take the
following precautions:
· Be sure the unit is connected to a 12V DC
power supply with a negative ground
connection.
· Do not open the top or bottom covers of the
unit.
· Do not install the unit in a spot exposed to
direct sunlight or excessive heat or humidity.
Also avoid places with too much dust or the
possibility of water splashing.
· When replacing a fuse, only use a new one
with the prescribed rating. Using a fuse with
the wrong rating may cause your unit to
malfunction.
· To prevent a short circuit when replacing a
fuse, first disconnect the wiring harness.
· If you experience problems during
installation, consult your Kenwood dealer.
· If the unit does not seem to be working right,
consult your Kenwood dealer.
FCC WARNING
This equipment may generate or use radio
frequency energy. Changes or modifications
to this equipment may cause harmful
interference unless the modifications are
expressly approved in the instruction manual.
The user could lose the authority to operate
this equipment if an unauthorized change or
modification is made.
This Class B digital apparatus complies with
Canadian ICES-003.
Cleaning the unit
If the front panel gets dirty, turn off the power
and wipe the panel with a dry silicon cloth or
soft cloth.
Do not wipe the panel with a hard cloth or a
cloth dampened by volatile solvents such as
paint thinner and alcohol. They can scratch the
surface of the panel and/or cause the indicator
letters to peel off.
To prevent batter rise
When the unit is used in the ACC ON position
without turning the engine ON, it depletes the
battery. Use it after starting the engine.
Protection function
There is a Protection function installed in the
unit to protect the unit and speakers from
various problems. When Protection operates,
the indicator informs you of the condition.

Installation
1. Install the installation fittings in the unit.
2. Attach the unit.
3. Install the terminal cover.
· Do not install in the below locations;
(Unstable location, In a location that interferes with driving, In a location that gets wet, In a
dusty location, In a place that gets hot, In a place that gets direct sunlight, In a location that
gets hit by hot air)
· Do not install the unit under the carpet. Otherwise heat build-up occurs and the unit may be
damaged.
· Install this unit in a location which allows heat to easily dissipate.
Once installed, do not place any object on top of the unit.
· The surface temperature of the amplifier will become hot during use. Install the amplifier in a
place where people, resins, and other substances that are sensitive to heat will not come into
contact with it.
· This unit has cooling fans to decrease the internal temperature. Be careful not to block the
cooling fan openings when installing the unit. Blocking these openings will inhibit the cooling of
the internal temperature and result in malfunction.
· When making a hole under a seat, inside the trunk, or somewhere else in the vehicle, check
that there is nothing hazardous on the opposite side such as a gasoline tank, brake pipe, or
wiring harness, and be careful not to cause scratches or other damage.
· Do not install near the dashboard, rear tray, or air bag safety parts.
· The installation to the vehicle should securely fasten the unit to a place in which it will not
obstruct driving. If the unit comes off due to a shock and hits a person or safety part, it may
cause injury or an accident.
· After installing the unit, check to make sure that electrical equipment such as the brake lamps,
turn signal lamps and windshield wipers operate normally.

The unit is a 5-channel amplifier
incorporating 2 stereo amplifiers and 1
monaural amplifier in a single body.
The stereo amplifier on one side is called
amplifier A, while the one on the other side is
amplifier B. The monaural amplifier is called
the amplifier SUB.
This unit is compatible with a large variety of
systems by combining the switches and
functions described in the following.
About D-class (SUB.CH)
A D-class amplifier uses an inaudible
frequency as a switching pulse to change the
pulse width to represent the music signal.
(Pulse Width Modulation: P.W.M.)
8 INPUT SENSITIVITY control
(A.CH/B.CH/SUB.CH)
Adjust this control according to the pre-out
level of the center unit connected to this
amplifier.
The sensitivities of amplifiers A, B and SUB
can be adjusted independently regardless
of the position of the input selector switch.
Refer to "Specifications" on the center
unit's instruction manual about the pre-out
level.
5 OPERATION switch
This switch is used to select the operation
mode of the amplifier.
This setting is valid for both the amplifier A
and B.
· STEREO position:
The amplifier can be used as a stereo
amplifier.
· MONO (Lch) position:
Amplifies the signal input from the left side
only. Set to this position and make bridged
connections to use as a high-power
monaural amplifier. (The input right signal is
not output.)
1 FILTER switch (A.CH/B.CH)
This switch allows to apply high-pass or
low-pass filtering to the speaker outputs.
· HPF (High-Pass Filter) position:
The filter outputs the band of higher
frequencies than the frequency set with the
HPF FREQUENCY control.
·OFF position:
The entire bandwidth is output without
filtering.
· LPF (Low-Pass Filter) position: (B.CH
only)
The filter outputs the band of lower
frequencies than the frequency set with the
LPF FREQUENCY control.
The speaker output is automatically turned
monaural (L+R) and the bass boost function
is activated.
2 HPF FREQUENCY control
(A.CH/B.CH)
Sets the cutoff frequency when the FILTER
switch is set to HPF.
4 B.CH LPF FREQUENCY control
Sets the cutoff frequency when the FILTER
switch is set to LPF.
6 SUB.CH LPF FREQUENCY control
This control adjusts the frequency band
output from this amplifier SUB.
7 INPUT SELECTER switch
(AB/A)
This switch toggles the input signal of
amplifier B.
· AB position:
The input for terminal A is output from
amplifier A, while the input for terminal B is
output from amplifier B.
NOTE

·A position:
The input for terminal A is output from
amplifiers A and B.
(AB/SUB)
This switch toggles the input signal of
amplifier SUB.
· AB position:
The input for terminals A and B input is
mixed and output from amplifier SUB.
· SUB position:
The input for the SUB terminal is output by
amplifier SUB.
3 B.M.S.(Bass management system)
switch
Bass boost centered on the frequency set
by the B.M.S. FREQUENCY control.
The B.M.S. only applies to the amplifier
SUB.
· +12 position:
Bass boost +12 dB
·OFF position:
Bass boost OFF
·REMOTE position:
Controls the B.M.S. from the Kenwood
center unit. (Refer to page 5)
0 B.M.S. FREQUENCY control
When the B.M.S. switch is set on "+12dB"/
"REMOTE" the emphasized center
frequency is adjusted.
9 V-COLOR (Variable color) button
Select the ON color for the indicator.
Every time the button is pressed, 7 fixed
colors and the variable color change.
The color can't be set when the indicator is
blinking.
Controlling the B.M.S. from the
Kenwood center unit
(B.M.S. : Bass management system)
When the B.M.S. switch is set in the
remote position, the bass boost amount
and frequency offset can be controlled from
the center unit.
