CONNECTIONS
Before making connections, be sure to turn the power off to all audio
components.
Insulation
tubes
for
the
speaker
terminals
and
the
power
supply
terminals
are
supplied
with
the
3522S.
Make
sure
the
speaker
leads
and
power
supply
leads
are
routed
through
these
tubes
separately
before
making final connections.
CAUTION:
Always
keep
the
RCA
inputs
of
the
3522S
connected
to
a
signal
source
while
the
amplifier
is
in
operation.
@ Speaker Output Terminals
The 3522S has a set of speaker outputs. Be sure to observe correct
speaker output polarity and phasing. In the stereo mode, connect the left
and right speaker outputs to their respective speakers. Connect the
positive output to the positive speaker terminal and the negative to
negative. In the bridged mode, the left positive output is connected to the
positive terminal of the speaker and the right-negative output is con-
nected to the negative terminal of the speaker. Do not use the negative
(~) speaker output as a common output for left and right speakers. Do
not connect the speaker outputs to the vehicle's chassis.
CAUTION:
Do not connect speaker leads together or to chassis soured
@ Speaker Input Leads
These leads are input leads for use with head units not equipped with
preamp outputs. When not using the RCA Line Input connectors, you
should connect these wires to the speaker output leads of your head unit.
The 3522S accepts input from high power or standard power head units.
@ RCA Input Connectors
Connect these connectors to the line will leads on your head unit using
RCA extension cables (sold separately). Be sure to observe correct
channel connections; Left to Left and Right to Right, Front to Front and
Rear to Rear.
@ Battery Lead (Yellow)
Connect this lead directly to the positive (+) terminal of the vehicle's
battery. Do not connect this lead to wiring in the vehicle's electrical
system. Be sure to add a 25A in-line fuse amp as close as possible to the
battery's positive (+) terminal. This fuse will protect your vehicle's electri-
cal system in case of a short circuit. If you need to extend this lead, the
wire gauge should be 10 AWG or larger.

© Remote Turn-On Lead (Blue/White)
Connect this lead to the remote turn-on or power antenna (positive
trigger, (+) 12V only) lead of your head unit.
@ Ground Lead (Black)
Connect
this
lead
to
a
clean,
bare
metal
spot
on
the
vehicle's
chassis.
Verify
this
point
to
be
a
true
ground
by
checking
for
continuity
between
that
point
and
the
negative
(—)
terminal
of
the
vehicle's
battery.
Ground
all
your
audio
components
to
the
same
point
on
the
chassis
to
prevent
ground
loops.
@ Insulation Tube
Use
these
tubes
to
cover
the
power
and
speaker
terminals
after
connec-
tions
have
been
made.
This
will
prevent
inadvertent
shorting
of
the
terminals.
