Connection
AcAUTION
• Secure all wiring with
cable clamps or
electrical tape.
Do not
allow
any
bare wiring to remain exposed.
•
Do not directly connect the
yellow
lead
of this product
to the
vehicle battery.
If
the lead
is
directly connected
to the battery, engine vibration may
eventually cause
the insulation to fail
at the point where the wire
passes from the passenger compartment into the
engine compartment.
If
the
yellow
lead's insulation
tears as a
result
of contact
with
metal
parts, short-
circuiting can occur, resulting in considerable danger.
•
It
is extremely dangerous to
allow
cables to become
wound around the steering column
or
shift lever. Be
sure to
install
this product, its
cables, and wiring
away
in such
so
that
they
will
not obstruct or hinder
driving.
•
Make
sure
that
the cables and wires
will
not interfere
with or become caught in
any
of the vehicle's
moving
parts, especially
the steering wheel, shift lever,
parking brake, sliding seat tracks, doors,
or
any of the
vehicle's
controls.
•
Do not route wires
where
they
will
be exposed to
high temperatures.
If
the insulation heats up, wires
may become damaged, resulting in a short circuit or
malfunction and permanent
damage
to the product.
•
Do not shorten
any
leads.
If
you do, the protection
circuit (fuse holder, fuse resistor or filter, etc.) may
fail
to work properly.
•
Never feed power to other electronic products by
cutting the insulation of the power supply
lead
of
this product and tapping into the
lead.
The
current
capacity of the
lead
will
be exceeded, causing
overheating.
•
Use
this
unit
with
a 12-volt battery and negative
grounding
only. Failure to
do
so may result in a fire or
malfunction
.
•
To
avoid shorts in
the
electrical system,
be
sure
to
discon-
nect
the(-)
battery cable before installation.
AWARNING
•
Use speakers over
50
W (output value) and between
4
n
to 8
n
(impedance value). Do not use 1
n
to 3
n
speakers for this unit.
•
The
black cable
is
ground. When
installing
this unit
or power
amp
(sold
separately), make sure to connect
the ground
wire
first. Ensure
that
the
ground
wire
is
properly connected to metal parts of the car's body.
The
ground
wire
of
the power
amp
and the one of this
unit or any other device must be connected to the car
separately with different screws.
If
the screw for the
ground wire loosens or
falls
out, it
could
result in fire
generation of smoke or malfunction.

To
avoid
short-circuiting,
cover the disconnected lead
with
insulating
tape. It
is especially
important
to insulate all
unused speaker leads,
which
if left uncovered may cause a
short circuit.
