Connecting the Unit
A
CAUTION
•Disconnect the negative
(-)
terminal
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.
•
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 bums.
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
I,ll
voltage.
•
If
the car stereo
is
kept on for along time while
Ithe engine is at rest
or
idling, the battery may
go
Idead.
Tum
the car stereo
off
when the engine is at
Irest
or
idling.
i • If the system remote control wire
of
the amplifier
Iis connected to the power terminal through the
!ignition switch (12 VDC), the amplifier will
II
always
be
on when the ignition is
on-
regardless
of
whether the car stereo
is
on
or
off. Because
of
Ithis. the battery could go dead
if
the engine is at
Irest
or
idling.
•DO NOT connect asubwoofer with alower
impedance than specified in the
"Connecting
the
Speaker Wires" section. Amplifier damage,
smoke, and overheating could result from anon-
specified connection. The amplifier surface could
also become hot to the touch and
minor
bums
could result.
•Connect either
of
two subwoofers to the amplifi-
er; I: asubwoofer with a350 W
or
larger nomi-
nal input and an impedance 4
Q,
or
2:
asub-
woofer with a600 W
or
larger nominal input and
an impedance 2Q.
If
the nominal input and
impedance are
out
of
the above ranges, the sub-
woofer may catch fire,
emit
smoke
or
become
damaged. .
•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.
