Installation and Connection Installation and Connection
• If your car's ignition does not have an ACC position,
connect the ignition wires to a power source that
can be turned on and off with the ignition key. If you
connect the ignition wire to a power source with a
constant voltage supply, such as with battery wires,
the battery may be drained.
• If the fuse blows, first make sure the wires are not
touching to cause a short circuit, then replace the old
fuse with one with the same rating.
• Insulate unconnected wires with vinyl tape or other
similar material. To prevent a short circuit, do not
remove the caps and do not let the cable out at the
ends of the unconnected wires or the terminals.
• Secure the wires with cable clamps and wrap vinyl
tape around the wires that comes into contact with
metal parts to protect the wires and to prevent short
circuit.
• Connect the speaker wires correctly to the terminals
to which they correspond. The unit may be damaged
·
or fail to work if you share the
them to any metal part in the car.
• When only two speakers are being connected to the
system, connect both connectors either to the front
output terminals or to the rear output terminals (do
not mix front and rear). For example, if you connect
the ª connector of the left speaker to a front output
·
terminal, do not connect the connector to a rear
output terminal.
