IMPORTANT!
Before
making
any
connections, disconnect
the
car's
battery until
the
installation
is
completed
to
avoid
possible
damage
to
the
electrical
system
*
The
+
12V
DC
power
cable
should
be
heavy
gauge
stranded copper cable
with
heavy
insulation,
since
it
draws
power
directly
from
the
positive battery terminal.
Select
the
cable
gauge
at
least 10mm'.
And
the
ground
cable
gauge
should
be
the
same
as
the
+
12V
DC.
*
Connect
the
+12V
Power
terminal
to
the
battery
(+)
position terminal.
An
in-line
fuse
must
be
installed
in
the
+12V
power
cable near
the
battery
less
than
50mm.
Without one,
an
accidental short circuit
could
pose
a fire
hazard
and
damage
your
amplifier. Connect
the
fuse
holder
to
battery, however,
do
not
install
fuse
at
this
time.
*
Connect
the
GROUND
Power
terminal direclly
to
the
battery
(-)
position terminal
or
the
car chassis.
Ensure
that all paint or other insulation
is
remove
from
around
the
hole
area,
and
using
self tapping
screw,
securely affix
the
bare
wire
ends
to
the
vehicle chassis.
Use
as
short
as
possible.
*
Many
radio's
and
other
music
sources
have
an
output terminal for connection of
the
remote
turn
on
of
the
power
amplifier.
CONNECT
the
output terminal
to
the
amplifier
REM
control jack. If a
radio
doesn't
have
a
remote
turn
on
feature,
you
can
connect
the
REM
pole
to
external
switch
for positive +12V ON/OFF.
*
To
help
minimize interference, it
is
best
to
run
the
power
cables
along
the
opposite
side
from
the
audio
cables.
Caution:
The
power cables must
be
connected tightly. A
loose
connection may
cause
malfunctions or interference noise
or
distortion.
