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 2 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.

connections possible according to applications, read
the instruction manual well to select the proper
setting and connection.
1.Remove the ignition key and disconnect the
negative
· terminal of the battery to prevent short
circuits.
2.Set the unit according to the intended usage.
3.Connect the input and output wires of the units.
4.Connect the speaker wires.
5.Connect the power wire, power control wire and
grounding wire following this order.
6.Install the installation fittings in the unit.
7.Attach the unit.
8.Connect the negative
· terminal of the battery.
CAUTION
· 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.
· Do not mount the unit in a place where the ducts
of the unit are blocked. 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.
