Connecting the Unit
CAUTION
· Disconnect the negative (­) terminal of the battery
to avoid the risk of short-circuit and damage to
the unit.
· Secure the wiring with cable clamps or adhesive
tape. To protect the wiring, wrap adhesive tape
around it where they lie against metal parts.
· Do not route wires where they will get hot, for
example where the heater will blow over them. If
the insulation heats up, it may become damaged,
resulting in a short-circuit through the vehicle
body.
· Make sure that wires will not interfere with mov-
ing parts of the vehicle, such as the gearshift,
handbrake or seat sliding mechanism.
· Do not shorten any wires. Otherwise the protec-
tion circuit may fail to work when it should.
· Never feed power to other equipment by cutting
the insulation of the power supply wire to tap
from the wire. The current capacity of the wire
will be exceeded, causing overheating.

To prevent damage
· Do not ground the speaker wire directly or con-
nect a negative (­) lead wire for several speakers.
· This unit is for vehicles with a 12-volt battery and
negative grounding. Before installing it in a recre-
ational vehicle, truck or bus, check the battery
voltage.
· If the car stereo is kept on for a long time while
the engine is at rest or idling, the battery may go
dead. Turn the car stereo off when the engine is at
rest or idling.
· If the system remote control wire of the amplifier
is connected to the power terminal through the
ignition switch (12 V DC), the amplifier will
always be on when the ignition is on-- regardless
of whether the car stereo is on or off. Because of
this, the battery could go dead if the engine is at
rest or idling.
· Speakers to be connected to the amplifier should
conform with the standards listed below. If they
do not conform, they may catch fire, emit smoke
or become damaged. The speaker impedance must
be 2 to 8 ohms for stereo connection, and 4 to 8
ohms for monaural and other bridge connection.
· Install and route the separately sold battery wire
as far away as possible from the speaker wires.
Install and route the separately sold battery wire,
ground wire, speaker wires and the amplifier as
far away as possible from the antenna, antenna
cable and tuner.
· Cords for this product and those for other prod-
ucts may be different colors even if they have the
same function. When connecting this product to
another product, refer to the supplied Installation
manuals of both products and connect cords that

Connecting the Unit
CAUTION
· Do not install in:
--Places where it could injure the driver or pas-
sengers if the vehicle stops suddenly.
--Places where it may interfere with the driver,
such as on the floor in front of the driver's
seat.
· Make sure that wires are not caught in the sliding
mechanism of the seats, resulting in a short-cir-
cuit.
· Confirm that no parts are behind the panel when
drilling a hole for installation of the amplifier.
Protect all cables and important equipment such
as fuel lines, brake lines and electrical wiring
from damage.
· Install tapping screws in such a way that the screw
tip does not touch any wire. This is important to
prevent wires from being cut by vibration of the
car, which can result in fire.
· To prevent electric shock, do not install the ampli-
fier in places where it might come in contact with
liquids.
· To ensure proper installation, use the supplied
parts in the manner specified. If any parts other
than the supplied ones are used, they may damage
internal parts of the amplifier, or they may
become loose causing the amplifier to shut down.
To prevent malfunction
· To ensure proper heat dissipation of the amplifier,
be sure of the following during installation.
--Allow adequate space above the amplifier for
proper ventilation.
--Do not cover the amplifier with a floor mat or
carpet.
· Do not install the amplifier near a door where it
may get wet.
· Do not install the amplifier on unstable places
such as the spare tire board.
· The best location for installation differs with the
car model and installation location. Secure the
amplifier at a sufficiently rigid location.
· Make temporary connections first and check that
the amplifier and the system operate properly.
· After installing the amplifier, confirm that the
spare tire, jack and tools can be easily removed.
Example of installation on the floor
mat or on the chassis
1. Place the amplifier where it is to be
installed. Insert the supplied tapping
screws (4

ADVERTENCIA
· Siempre utilice el cable de batería rojo especial y
el cable de tierra [RD-223], vendidos separada-
mente. Conecte el cable de batería directamente al
terminal positivo de la batería del vehículo (+) y
el cable de tierra a la carrocería del vehículo.
· No toque en el amplificador con las manos
mojadas. Caso contrario, usted puede llevar un
choque eléctrico. Igualmente, no toque en el
amplificador cuando esté mojado.
· Para seguridad del tráfico y para mantener condi-
ciones de conducción seguras, mantenga el volu-
men suficientemente bajo de manera que aun se
pueda escuchar el sonido del tráfico normal.
· Verifique las conexiones del suministro de energía
y altavoces para ver si el fusible del cable de
batería vendido separadamente o el fusible del
amplificador se queman. Detecte la causa y solu-
cione el problema, y reemplace el fusible con un
otro del mismo tamaño y régimen.
· Para evitar mal funcionamiento del amplificador y
altavoces, el circuito de protección cortará la ali-
mentación al amplificador (el sonido se detendrá)
cuando se produzca una situación anormal. En tal
caso, apague el sistema y verifique la conexión de
la alimentación y altavoces. Detecte la causa y
resuelva el problema.
· Contacte a su distribuidor si no puede detectar la
causa.
· Para evitar choques eléctricos o cortocircuitors
durante la conexión e instalación, asegúrese de
desconectar el terminal negativo (­) de la batería
antes de proceder.
· Confirme que ninguna parte quede detrás del
panel, cuando perfore un orificio para la insta-
lación del amplificador. Asegúrese de proteger
todos los cables y equipos importantes, tales como
líneas de combustibles, líneas de frenos y el
cableado eléctrico.
