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.

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

PROTECTION indicator lights 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 with a current capacity

greater than the unit’s fuse capacity. (Use a power

wiring cord with the range of 14 mm² (AWG 6) to 21

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.

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 2Ω or greater (for

stereo connections), or 4Ω 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.
