• When extending the ignition, battery, or ground
wires, make sure to use automotive-grade wires or
other wires with a 3mm2 (AWG12) 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.

• Connect the ground wire to a metal part of the
car chassis that acts as an electrical ground
passing electricity to the battery‘s negative -
terminal. Do not turn the power on if the ground
wire is not connected.
• Be sure to install a protective fuse in the power
cord near the battery. The protective fuse should
be the same capacity as the unit’s fuse capacity
or somewhat larger.
• For the power cord and ground, use a vehicle
type (fireproof) power wring cord with a current
capacity greater than the unit’s fuse capacity.
(Use a power wiring cord with a diameter of 3
mm2 (AWG 12) or greater.)
• When more than one power amplifier are going
to be used, use a power supply wiring wire and
protective fuse of greater current-handling
capacity than the total maximum current drawn
by each amplifier.

• 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.
• 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.

To prevent damage to the machine, take the
following precautions:

• If the fuse blows, check wires for shorts, then
replace the fuse with one of the same rating.
• Check that no unconnected cables or connectors
are touching the car body. Do not remove caps from
unconnected cables or connectors to prevent short
circuits.
• Connect the speaker wires to appropriate speaker
connectors separately. Sharing the negative wire of
the speaker or grounding speaker wires to the metal
body of the car can cause this unit to fail.
• After installation, check that the brake lamps,
winkers, and wipers work properly.

• 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.
■ Speaker Selection
• The rated input power of the speakers that are
going to be connected should be greater than
the maximum output power (in Watts) of the
amplifier. Use of speakers having input power
ratings that are less than the output power of
the amplifier will cause smoke to be emitted as
well as damage.

• The impedance of the speakers that are going to
be connected should be 2Ω or greater (for
stereo connections), or 4Ω or greater (for
bridged connections). When more than one set
of speakers are going to be used, calculate the
combined impedance of the speakers and then
connect suitable speakers to the amplifier.
• To prevent a short circuit when replacing a fuse, first
disconnect the wiring harness.

• The genuine-accessory car stereo shall have a
maximum power output of no more than 40 W.
• Do not connect the speaker output leads from
a power amplifier (Optional) to the speaker
level input terminals of this unit, for this may
cause malfunction or damage.
• Do not connect cables and leads to both RCA
cable input jacks and the speaker level input
terminals simultaneously, for this may cause
malfunction or damage.
• Connect the power control lead to a power
supply which can be turned ON/OFF by the
ignition key switch (ACC line). With this
connection, shock noise may be generated
when the power of the genuine-accessory car
stereo is switched ON/OFF.

■ Cleaning the unit
• If you wish to bridge-connect a speaker, the
speaker impedance must be no less than 4
ohms. Connecting a speaker with an
impedance lower than 4 ohms may damage
the unit.
• Be sure to connect capacitors to speakers to
which high frequencies will be passed.
Failure to do so will result in a drop of the
combined impedance with the subwoofer.
• Ensure that the withstand voltage and
current ratings of the capacitors (C) and coils
(L) are sufficient.

If the front panel gets dirty, turn off the power and
wipe the panel with a dry silicon cloth or soft cloth.
• After installing the unit, check to make sure that

normally.
