Combined impedance
Cleaning the unit
Ifthe front panel gets dirty, turn offthe power and
wipe the panel with adry silicon cloth or soft cloth.
•Connect the ground wire
to
ametal part
of
the
car
chassis
that acts
as
an
electrical ground passing
electricity
to
the battery's negative 8terminal.
Do not turn the power on
if
the ground wire
is
not
connected.
•
Be
sure
to install aprotective fuse
in
the power
cord near the battery. The protective fuse should
be the
same
capacity
as
the unit's fuse capacity or
somewhat larger.
•
For
the power cord and ground,
use
avehicle type
(fireproof) power wring cord with acurrent capacity
greater than the unit's fuse capacity.
(Use
apower
wiring cord with adiameter
of
5
mm
2
(AWG
10)
or
greater.)
•When more than one power amplifier
are
going
to be
used,
use
apower supply wiring wire and
protective fuse
of
greater current-handling capacity
than the total maximum current drawn by each
amplifier.
Speaker selection
•
The
input
power
of
the speakers that
are
going to
be connected should
be
greater than the
output
power
(in
Watts)
of
the amplifier.
Use
of
speakers
having
input
power ratings that
are
less
than the
output
power
of
the amplifier will cause smoke to
be
emitted
as
well
as
damage.
•
Use
speakers that have
an
impedance
of
20
or
greater. When more than one
set
of
speakers
are
going to be
used,
calculate the combined
impedance
of
the
speakers
and then connect
suitable
speakers
to
the amplifier.
ACAUTION
NOTE
AWARNING
To
prevent injury or fire, take the following
precautions:
•When extending the ignition, battery, or ground
wires, make
sure
to
use
automotive-grade wires
or other wires with a 5 mm2
(AWG
10)
or more to
prevent wire deterioration and damage to the wire
coating.
•
To
prevent ashort circuit, never put or leave any
metallic objects (such
as
coins or metal tools) inside
the unit.
•Ifthe unit starts to emit smoke or strange smells,
turn offthe power immediately and consult your
Kenwood dealer.
Do
not touch the unit during
use
because the
surface
of
the unit becomes hot and may
cause
burns
if
touched.
Mounting and wiring this product requires
skills
and
experience.
For
safety's
sake,
leave
the mounting
and wiring work
to
professionals.
To
prevent damage
to
the
machine, take
the following precautions:
Be
sure
the unit
is
connected to a
12V
DC
power
supply with anegative ground connection.
Do not open the
bottom
covers
of
the unit.
•Do not install the unit
in
aspot exposed to direct
sunlight or excessive heat or humidity. Also avoid
places with too much dust or the possibility
of
water splashing.
•When replacing a
fuse,
only
use
anew one with
the prescribed rating. Using afuse with the wrong
rating may cause your unit to malfunction.
•
To
prevent ashort circuit when replacing a
fuse,
first
disconnect the wiring
harness.
•Ifyou experience problems during installation,
consult your Kenwood dealer.
•If the unit does
not
seem
to be working right,
consult your Kenwood dealer.
Wiring
•
Take
the battery wire for this unit directly from
the battery. If
it's
connected
to
the vehicle's wiring
harness,
it
can
cause
blown
fuses
etc.
•If a
bUZZing
noise
is
heard from the
speakers
when
the engine
is
running, connect aline noise filter
(optional) to each
of
the battery wire.
•Do not allow the wire to directly contact the edge
of
the iron plate by using Grommets.
2
English
Do
not
wipe the panel with ahard cloth or acloth
dampened by volatile solvents such
as
paint thinner
and alcohol. They
can
scratch the surface
of
the panel
and/or cause the indicator letters to peel off.
To
prevent batteryfrom running out
When the unit
is
used
in the
ACC
ON
position
without
turning the engine
ON,
it depletes the battery.
Use
it
after starting the engine.
