! Use of this unit in conditions other than the
following could result in fire or malfunction.
— Vehicles with a 12-volt battery and negative
grounding.
— Speakers with 50 W (output value) and 4 ohm
to 8 ohm (impedance value).
! To prevent a short-circuit, overheating or mal-
function, be sure to follow the directions
below.
— Disconnect the negative terminal of the bat-
tery before installation.
— Secure the wiring with cable clamps or adhe-
sive tape. Wrap adhesive tape around wiring
that comes into contact with metal parts to
protect the wiring.
— Place all cables away from moving parts,
such as the shift lever and seat rails.
— Place all cables away from hot places, such
as near the heater outlet.
— Do not connect the yellow cable to the battery
by passing it through the hole to the engine
compartment.
— Cover any disconnected cable connectors
with insulating tape.
— Do not shorten any cables.
— Never cut the insulation of the power cable of
this unit in order to share the power with
other devices. The current capacity of the
cable is limited.
— Use a fuse of the rating prescribed.
— Never wire the negative speaker cable directly
to ground.
— Never band together negative cables of multi-
ple speakers.
! When this unit is on, control signals are sent
through the blue/white cable. Connect this
cable to the system remote control of an ex-
ternal power amp or the vehicle
’s auto-anten-
na relay control terminal (max. 300 mA
12 V DC). If the vehicle is equipped with a
glass antenna, connect it to the antenna
booster power supply terminal.
! Never connect the blue/white cable to the
power terminal of an external power amp.
Also, never connect it to the power terminal
of the auto antenna. Doing so may result in
battery drain or a malfunction.
! The black cable is ground. Ground cables for
this unit and other equipment (especially,
high-current products such as power amps)
must be wired separately. If they are not, an
accidental detachment may result in a fire or
malfunction.
