Safety precautions
WARNING
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 5 mm2 (AWG 10) 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.
• Mounting and wiring this product requires skills and
experience. For safety’s sake, leave the mounting
and wiring work to professionals.
CAUTION
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 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.
NOTE
• If you experience problems during installation,
consult your Kenwood dealer.
• If the unit does not seem to be working right,
consult your Kenwood dealer.
Wiring
• Take the battery wire for this unit directly from
the battery. If it’s connected to the vehicle’s wiring
harness, it can cause blown fuses etc.
• If a buzzing noise is heard from the speakers when
the engine is running, connect a line noise filter
(optional) to each of the battery wire.
• Do not allow the wire to directly contact the edge
of the iron plate by using Grommets.
• 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 5 mm2 (AWG 10) 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.
Speaker selection
• The input power of the speakers that are going to
be connected should be greater than the 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.
• Use speakers that have an impedance of 2Ω or
greater. 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.

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.
CAUTION
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 battery from running out
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.
