Connecting the Unit
A
CAUTION
•Disconnect the negative
(-)
tenninal
of
the bat-
tery 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 it 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 ashort-circuit through the vehicle
body.
A
CAUTION:
To
prevent
damage
and/or
injury
•Do not ground the speaker wire directly or con-
nect anegative
(-)
lead wire for several speakers.
•This unit is for vehicles with a12-volt battery and
negative grounding. Before installing it
in
arecre-
ational vehicle, truck
or
bus, check the battery
voltage.
•
If
the car stereo is kept on for along time while
the engine is at rest
or
idling, the battery may go
dead.
Tum
the car stereo
off
when the engine is at
rest or idling.
•
If
the system remote control wire
of
the amplifier
is connected 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
the engine is at
rest or idling.
•Make sure that wires will not interfere with mov-
ing parts
of
the vehicle, such as the gearshift,
handbrake or seat sliding mechanism.
•Do not shorten any wires. Otherwise the protec-
tion 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.
•Never replace the fuse with one
of
greater value
or rating than the original fuse. Use
of
an improp-
er
fuse could result in overheating and smoke and
could cause damage to the product and injury
including burns.
•Speakers to be connected to the amplifier should
conform with the standards listed below.
If
they
do not conform, they may catch fire, emit smoke
or become damaged. The speaker impedance
must be 2to 8ohms. But in case
of
two-channel
and other bridge connections, the speaker
impedance must be 4to 8ohms.
•Install and route the separately sold battery wire
as far away as possible from the speaker wires.
Install and route the separately sold battery wire,
ground wire, speaker wires and the amplifier as
far away as possible from the antenna, antenna
cable and tuner.
