Cautions on Power Supply Wires
Use
the
specified wire size according
to
the
total
fuse capacity
of
the
amplifier
to
be installed and
the
wire
length.
For details
on
the
wire
size
to
be used, refer
to
the
supplied "Cautions on Power Supply Wires Connection"
and
the
following
connection example.
Connection example when installing an amplifier alone
• When
the
wire length from
the
amplifier
to
the
vehicle's battery
is
5 m
Wire size used
for
(A):
S-A60M/S-ASSV: 4 AWG/21

• External
Fuse
capacity: Make
it
equal
to
or
larger than
the
fuse capacity
of
the
amplifier
S-A60M/S-ASSV: equal
to
or
larger
than
60

cables exceed 1 m,
or
if
you connect more than one amplifier, a
distribution block should be used.
