FUNCTIONS
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.
+
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
size
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.
7.
Low
Pass
Filter
Control
(Mono Block)-
This
control
is
used
to
select
the
desired low
pass
x-over
frequency.
The
frequency
can
be
adjusted from
40Hz
to
220Hz
for
all
bass
mono
models.
8.
Subsonic
Filter
Control
(Mono Block)-
This
control
can
filter
out
unwanted low frequency
from
1OHz
(OFF)
to
50Hz.
This
function
should
only
be
used
with
vented
enclosures.
