Input/Output
(R-A7SM
only)
• The
input
is stereo
but
the
output
is
monaural.
• Reversing subwoofer polarity (swapping
positive and negative connections
to
the
subwoofer) may be desirable in some
installations
for
optimum
bass
performance.
About

In
the
bridged mode, connect
the
left
positive
to
the
positive terminal
of
the
speaker and
the
right
negative

not
use
the
speaker(-) terminals
as
a
common
lead between
the
left

right
channels.
NOTE:
• Do
not
connect the speaker(-) terminal
to
the
vehicle's chassis.

• For details on
the
wires size
to
be used, refer
to
the
supplied "Cautions
on
Power Supply Wires
Connection" and "Cautions
on
Power Supply
Wires" (page 20), and then use
the
wire
of
the
specified
size.
0 Remote Turn-On Lead (sold separately)
Connect this lead
to
the
remote
turn-on
(positive trigger,(+)
12
V only) lead
of
your head
unit.
If
a remote turn-on lead
is
not
available,
see
"CONNECTION
CHECK
LIST"
section
on
page 7
for
alternative method.
• When connecting
the
speaker
output
leads
of
the
head
unit
to
this
unit
with
a Speaker-RCA
Conversion cable (sold separately), you
do
not
need
to
connect
the
remote
turn-on
lead,
owing
to
the
"REMOTE
SENSING"function
of
this unit. However,
the
"REMOTE
SENSING"
function may
not
work
depending on
the
signal source connected. In such a
case,
connect
the
remote
turn-on
lead
to
an
incoming
power
supply cord (accessory
power) in
the
ACC
position.
0 Ground Lead (sold separately)
Connect this lead securely
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 while keeping
wire length
as
short
as
possible.
• For details on
the
wires size
to
be used, refer
to
the
supplied "Cautions on Power Supply Wires
Connection" and "Cautions on Power Supply
Wires" (page 20), and then use
the
wire
of
the
specified
size.
