No ACC position
• To prevent a short-circuit, overheating or
malfunction, be sure to follow the
directions below.
– Disconnect the negative terminal of the
battery before installation.
– Secure the wiring with cable clamps or
adhesive 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
multiple 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 external power amp or the
vehicle's auto-antenna relay control
terminal (max. 300mA 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.
