INSTALLATION/CONNECTION

Warning
• The unit can only be used with a 12 V DC power supply, negative ground.
• Disconnect the battery's negative terminal before wiring and mounting.
• Do not connect Battery wire (yellow) and Ignition wire (red) to the car chassis or Ground wire
(black) to prevent a short circuit.
• To prevent short circuit:
– Insulate unconnected wires with vinyl tape.
– Be sure to ground this unit to the car's chassis again after installation.
– Secure the wires with cable clamps and wrap vinyl tape around the wires that comes into
contact with metal parts to protect the wires.
Caution
• For safety's sake, leave wiring and mounting to professionals. Consult the car audio dealer.
• Install this unit in the console of your vehicle. Do not touch the metal parts of this unit during and
shortly after use of the unit. Metal parts such as the heat sink and enclosure become hot.
• Do not connect the wires of speakers to the car chassis or Ground wire (black), or connect
them in parallel.
• Connect speakers with a maximum power of more than 50 W. If the maximum power of the
speakers is lower than 50 W, change the [AMP GAIN] setting to avoid damaging the speakers.
( 24)
• Mount the unit at an angle of less than 30º.
• If your vehicle wiring harness does not have the ignition terminal, connect Ignition wire (red) to
the terminal on the vehicle's fuse box which provides 12 V DC power supply and is turned on and
off by the ignition key.
• Keep all cables away from heat dissipate metal parts.
• After the unit is installed, check whether the brake lamps, blinkers, wipers, etc. on the car are
working properly.
• If the fuse blows, first make sure the wires are not touching car's chassis, then replace the old fuse
with one that has the same rating.
