FUNCTIONS
1.
Speakers
-
Connect
speakers/subwoofers
to

Be
sure
to
check wire for proper
polarity.
Never
connect
the
speaker

Volt
Power)-
Connect
this terminal
through a
FUSE

CIRCUIT
BREAKER
to
the
positive
terminal
of
the

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-
This
terminal
turns
on
the
amplifier
when
(+)
12
volt
is
applied
to
it.
Connect
it
to
the
remote
turn
on

Use
the
shortest distance
possible.
It
is
always
a
good
idea
to
replace

time
with a
cable
equal
or
larger
than
the
new
amplifier
power
cable.
CAUTION:

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.
