• Use this unit in other than the following
conditions 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 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. To protect the wiring, wrap
adhesive tape around them where they lie
against metal parts.
— Place all cables away from moving parts, such
as gear shift and seat rails.
— Place all cables away from hot places, such as
near the heater outlet.
— Do not pass the yellow cable through a hole
into the engine compartment to connect to a
battery.
— 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 to other
equipment. Current capacity of the cable is
limited.
— Use a fuse of the rating prescribed.
— Never wire the speaker negative cable directly
to ground.
— Never band together multiple speaker’s
negative cables.
• Control signal is output through blue/white cable
when this unit is powered on. Connect it to an
external power amp’s system remote control or
the vehicle’s auto-antenna 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 blue/white cable to external power
amp’s power terminal. Also, never connect
it to the power terminal of the auto antenna.
Otherwise, battery drain or malfunction may
result.
• IP-BUS connectors are color-coded. Be sure to
connect connectors of the same color.
• Black cable is ground. This cable and other
product’s ground cable (especially, high-current
products such as power amp) must be wired
separately. Otherwise, fire or malfunction may
result if they are accidentally detached.
