Connection
•Installationprocedure
Since there are large variety
of
settings and
connections possible according
to
applications, read
the
instruction manual well
to
select the proper
setting and connection.
1.
Remove the ignition key and disconnect
the
negative eterminal
of
the battery
to
prevent short
circuits.
2.
Set
the
unit
according
to
the
intended usage.
3.
Connect the
input
and
output
wires
of
the units.
4.
Connect the speaker wires.
5.
Connect the
power
wire,
power
control wire and
grounding wire following this order.
6.
Install
the
installation fittings in the unit.
7.
Attach the unit.
8.
Connect the negative eterminal
of
the
battery.
IAWARNING I
To
prevent fire caused by ashort in the wiring,
connect afusible link or breaker nearby the battery's
positive terminal.
IACAUTION
•Ifsound
is
not
output
normally, immediately turn
power
off
and check connections.
•
Be
sure
to
turn the power
off
before changing the
setting
of
any switch.
•If
the
fuse blows, check wires for shorts, then replace
the fuse
with
one
of
the same rating.
•Check
that
no unconnected wires or connectors
are
touching the car body. Do
not
remove caps from
unconnected wires or connectors
to
prevent short
circuits.
•Connect the speaker wires
to
appropriate speaker
connectors separately. Sharing
the
negative wire
of
the speaker or grounding speaker wires
to
the metal
body
of
the car can cause this
unit
to
fail.
•After installation, check
that
the brake lamps,
winkers, and wipers
work
properly.
•Wiring
•
Take
the
battery wire for this unit directly from the
battery. Ifit's connected
to
the vehicle's wiring
harness, it
can
cause
blown
fuses etc.
•Ifabuzzing 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.
•Connect the ground wire
to
ametal part
of
the
car
chassis
that
acts
as
an
electrical ground passing
electricity
to
the battery's negative eterminal.
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.
•
Speakerselec~on
•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.
•The impedance
of
the speakers
that
are going
to
be connected should be
20
or greater (for
stereo connections), or
40
or greater (for bridged
connections). 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.
