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
