FUNCJ"IONS
1.
Speakers- Connect speakers/subwoofers
to
these terminals.
Be
sure
to
check wire for proper
polarity. Never connect
the
speaker cables
to
the
chassis ground.
2.
+BATT(+
12
Volt Power)- Connect this terminal through a
FUSE
or
CIRCUIT
BREAKER
to
the
positive terminal of
the
vehicle battery
or
the
positive terminal of
an
isolated
audio
system
battery.
WARNING:
Always protect this power cable
by
installing a
fuse
or
circuit breaker of
the
appropriate
gauge
within
18
inches
(45cm)
of
the
battery terminal connection.
3.
Remote
Turn
On-
This
terminal turns
on
the
amplifier when(+)
12
volt
is
applied
to
it.
Connect
it
to
the
remote
turn
on
lead
of
the
head
unit
or
signal source.
4.
GND- Connect this cable directly
to
the
frame of
the
vehicle. Make
sure
the
metal
frame
has
been
stripped of
all
paint down
to
the
bare
metal.
Use
the
shortest distance possible.
It
is
always
a
good
idea
to
replace
the
factory
ground
at this
time
with a cable
equal
or
larger
than
the
new
amplifier power cable.
CAUTION:
Do
not connect this terminal directly
to
the
vehicle battery
ground terminal
or
any
other factory
ground
points.
5.
RCA
Input
Jacks-
These
RCA
input jacks
are
for
use
with source units that
have
RCA
outputs. A
source unit with a
minimum
level of
200mV
is
required for proper operation.
The
use
of
high
quality twisted pair cables
is
recommended
to
decrease
the
possibility of radiated
noise
entering
the
system.
6.
Gain
Control-
The
Gain
control will
match
the
amplifier's sensitivity to
the
source units signal
voltage.
The
operating
range
is
5V
to
200mV.
NOTE:
This
is
NOT
a
volume
control.
