Connecting the Unit
C\ 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
8 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.)

Connect the male terminal of this wire
to the blue wire of the car stereo
(system control terminal). The female
terminal can be connected to the auto-
antenna relay control terminal.
\f the car stereo does not have a
system remote control terminal,
connect the male terminal to the power
terminal through the ignition switch.

nection instructions.
@ 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.

Connecting the Power Terminal
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

Pass the special red battery wire from the
engine compartment to the interior of the
vehicie.

@ If many units are connected
'f 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.
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
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 voitage.
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.
