Safety precautions
2WARNING
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 battery, or ground wires, make sure to use automotive-
grade wires or other wires with the range of 10 mm2 (AWG 8) to 25 mm2 (AWG
4) 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.
2CAUTION
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.
· Digital processing is performed inside this amplifier. Therefore, when used in
conjunction with other amplifiers, there may be a slight delay. If this occurs,
input the pre-output audio from this amplifier into the other amplifier.

Information on Disposal of Old Electrical and Electronic
Equipment (applicable for EU countries that have adopted
separate waste collection systems)
Products with the symbol (crossed-out wheeled bin) cannot be
disposed as household waste.
Old electrical and electronic equipment should be recycled at a
facility capable of handling these items and their waste byproducts.
Contact your local authority for details in locating a recycle facility
nearest to you. Proper recycling and waste disposal will help conserve
resources whilst preventing detrimental effects on our health and the
environment.
This Product is not installed by the manufacturer of a vehicle on the production
line, nor by the professional importer of a vehicle into an EU Member State.
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.
2CAUTION
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
There is a Protection function installed in the unit to protect the unit and
speakers from various problems. When Protection operates, the display informs
you of the condition.
Display
Informations
"E-01"
When the inside of the unit is overheating.
"E-02"
When the unit has failed and direct current voltage is generated to the speaker's
output.
NOTE
Turn the power OFF and release the protection. If the "E-02" code does not disappear,
contact your Kenwood dealer.
"E-03"
When the speaker cord is shorted.
When the speaker output is in contact with the vehicle ground.
"E-99"
When a system error occurs.
Press the Reset button. If the "E-99" code does not disappear, contact your Kenwood
dealer.
"VOLT" display is
blinked.
When voltage gets out of operation range.
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 between 10 mm2 (AWG 8) to 25 mm2 (AWG 4).)
· 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 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.

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.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.
2CAUTION
· 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.

2WARNING
To prevent fire caused by a short in the wiring,
connect a fusible link or breaker nearby the
battery's positive terminal.
2CAUTION
· 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,
winkers, and wipers work properly.
