3 - Connections
Only
use
the
cables
recommended
in
the
user
manual. The
wire
gauge
of
power
cables
must
correspond
with
those
indicated
in
the
table
(paragraph
31)
and
depends
on
the
power
of
your
equipment
and
the
length
of
cable
required. Use
double
or
triple
shielded
RCA
cables
to
avoid
any
interference
with
the
low-
level signal.
CAUTION
Avoid
routing
power
supply
cables
close
to
input/output
cables, close
to
your
car's aerial
or
close
to
sensitive
equipment
and
harnesses.
High-current
power
supply
cables can cause
static/interference
that
affects
audio
signals.
Keep
the
cables
as
short
as possible
to
optimise
the
quality
of
the
installation. This will also
limit
signal loss.
3.1
- Connecting
the
power
supply
The
required
wire
gauge
of
power
cables
depends
on
the
length
of
cabling
to
the
battery
and
to
the
ground,
the
minimum
recommendations
are
shown
in
the
table
below:

Compliance
with
these
wiring
rules is essential
for
the
safety
of
you
r
electrical
installation.
It
is
also
important
for
maintaining
maximum
performance
of
your
FSP-8.
Route
the
positive
(
+)
power
cable.
Get
hold
of
the
negative
(-
or
ground)
power
cable. This
cable
should
be
as
short
as
possible
and
ideally
shouldn't
be
any
longer
than
3ft
(lm),
to
ensure a
perfect
connection
between
the
FSP-8
and
the
chassis
of
the
vehicle.
The
cable
and
wire
gauge
must
comply
with
the
table
above.
Find
a
suitable
grounding
point,
then
sand
it
to
remove
any
traces
of
paint
or
other
coating, in
order
to
optimise
the
quality
of
the
contact
point.
Drill a
hole
in
the
metal
that
you
have
previously
sanded,
making
the
hole
the
same
diameter
as
the
screw
you
are
using,
and
making
sure
that
there
are
no
fuel lines, cables
or
any
other
sensitive
vehicle
devices nearby.

Screw
the
cable
securely
to
the
FSP-8's
GND
terminal. Tin
the
other
end
of
the
cable
and
then
crimp
or
weld
it
to
the
intended
terminal
lug. Pass
the
screw
through
terminal
lug,
and
fasten securely in
place
with
the
nut.
3.2.1 - Connecting
the
inputs
to
the
FSP-8
Your head unit
is
equipped
with
low-level RCA or optical outputs.
Route
together
the
modulator
cables
(RCA)
or
optical
cables,
the
REM
cable
from
the
head unit,
and
the
REMOTE
CONTROL
cable
(if
the
remote
control
is installed,
RS-485
connector),
ensuring
you
isolate
them
from
other
powerful
automobile
accessories,
particularly
electric
motors
(windscreen
wipers
etc.).
Your head unit
is
only
equipped
with
amplified outputs (speaker driver
outputs)
.
Route
together
the
modulator
cables
from
the
head
unit
and
the
REMOTE
CONTROL
cable
(if
the
remote
control
is installed,
RS-485
connector),
ensuring
you
isolate
them
from
other
powerful
automobile
accessories,
particularly
electric
motors
(windscreen
wipers
etc.).
In
this
case,
connecting
the
REM
input
is
not
essential
as
the
FSP-8 is
equipped
with
a DC
detection
system
on
the
high-level inputs. This
function
is
not
available
on
the
AUX
and
OPTICAL
inputs.
