Connecting the Unit
CAUTION
• Remove the negative (–) terminal of the
battery to avoid the risk of short-circuit
and damage to the unit.
• Secure the wiring with cable clamps or
adhesive tape. To protect the wiring,
wrap adhesive tape around them where
they lie against metal parts.
• Do not route wires where they will get
hot, for example where the heater will
blow over them. If the insulation heats
up, it may become damaged, resulting in
a short-circuit through the vehicle body.
• Make sure that wires will not interfere
with moving parts of the vehicle, such as
the gearshift, handbrake or seat sliding
mechanism.
• Do not shorten any leads. Otherwise the
protection circuit may fail to work when it
should.
• Never feed power to other equipment by
cutting the insulation of the power supply
wire to tap from the wire. The current
capacity of the wire will be exceeded,
causing overheating.
• Always use the special red battery power
and ground wire [RD-222], which is sold
separately. Connect the special red
battery power cord directly to the car
battery and the black ground wire to the
car body. (The special red battery power
and ground wire [RD-222] are designed
so that the amplifier can be connected
safely.)
To prevent damage
• Do not ground the speaker wire directly
or connect a negative (–) wire for several
speakers.
• Speakers to be connected to the amplifier
should conform with the standards listed
below. Otherwise damage will be caused
to the speaker. The speaker impedance
must be 2 to 8 ohms.

If many units are connected
• If you let the car engine idle for a long
time with the car stereo on, the battery
may go dead. Turn the car stereo off
when the engine is idling.
• If the blue lead of the amplifier is connect-
ed to the power terminal through the
ignition switch (12 VDC), the amplifier will
always be on when the ignition is on—
regardless of whether the car stereo is on
or off. Because of this, the battery could
Power
go dead if you let the engine idle.
• This unit is for vehicles with a 12-volt
battery and negative grounding. Before
installing it in a recreational vehicle, truck,
or bus, check the battery voltage.
• Install and route the separately sold
special red battery wire [RD-222 ] as
faraway as possible from the speaker
wires. Install and route the separately
sold special red battery wire and ground
wire [RD-222 ], speaker wires, and the
amplifier as faraway as possible from the
antenna, antenna cable and tuner.

After making all other connections
at the amplifier, connect the battery
lead terminal of the amplifier to the
positive (+) terminal of the battery.
