Installation procedure
Since there are large variety of settings and
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. Remove the Dressing cover.
4. Connect the input and output wires of the
units.
5. Connect the speaker wires.
6. Connect the power wire, power control wire
and grounding wire following this order.
7. Install the installation fittings in the unit.
8. Attach the unit.
9. Attach the Dressing cover.
10. 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.
· This unit has cooling fan to decrease the internal
temperature. Do not mount the unit in a place
where the cooling fan and 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.

WARNING
Remove the ignition key and disconnect the negative
· terminal of the
battery to prevent short circuits.
·
WARNING
Particular attention must be given to making good electrical
contact at the amplifier-output and speaker terminals.
Poor or loose connections can cause sparking or burning
at the terminals because of the very high power that the
amplifier can deliver.
CAUTION
· If sound is not output normally, immediately turn power off
and check connections.
· Be sure to turn the power off before changing the setting of
any switch.
· If the fuse blows, check wires for shorts, then replace the fuse
with one of the same rating.
· Check that no unconnected wires or connectors are touching
the car body. Do not remove caps from unconnected wires 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, turn signal lamps
and windshield wipers work properly.

WARNING
To prevent fire caused by a short in the wiring,
connect a fusible link or breaker nearby the
battery's positive terminal.

Safety precautions
WARNING
To prevent injury or fire, take the following precautions:
· Mounting and wiring this product requires skills and
experience. For safety's sake, leave the mounting and
wiring work to professionals.
· When extending the ignition, battery, or ground wires,
make sure to use automotive-grade wires or other wires
with the range of 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.
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 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.
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.
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 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
The protection function is activated in the following
situations:
This unit is equipped with a protection function for
protecting this unit and your speakers from various
accidents or problems that can occur.
When the protection function is triggered, the power
indicator goes off and the amplifier stops operating.
· When a speaker wire may be short-circuited.
· When a speaker output contacts ground.
· When the unit malfunctions and a DC signal is sent to the
speaker output.
7 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. (Use a power wiring cord
with the range of 5 mm² (AWG 10) or more.
· 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.
7 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 2 or greater (for stereo
connections), or 4 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
