This
section
focuses
on
some
of
the
vehicle
considerations
for
install-
ing
your
new
amplifier.
Pre-planning
your
system
layout
and
best
wiring
routes
will
save
installation
time.
When
deciding
on
the
layout
of
your
new
system,
be
sure
that
each
component
will
be
easily
accessible
for
making
adjustments.
h..
If
you
feel
unsure
about
installing
this
sys-
ill
CAUTION
tem
yourself,
have
it
installed
by
a
qualified
technician.
t
CAUTION
Before
installation,
disconnect
the
batte
ry
neg
-
~
alive(
-)
terminal
to
prevent
damage
to
the
unit,
fire
and/or
possible
injury.
Before
beginning
any
installation,
follow
these
simple
rul
es
:
1.
Be
sure
to
carefully
read
and
under
s
tand
the
instructions
before
attempting
to
i
nstall
the
unit.
2.
For
safety
,
disconnect
the
negative
lead
from
the
battery
pr
i
or
to
beginning
the
installation.
3.
For
easier
assembly,
we
suggest
you
run
all
wires
prior
to
mounting
your
unit
in
place.
4.
Route
all
of
the
RCA
cables
close
together
and
away
from
any
high
current
wires.
5.
Use
high
quality
connectors
for
a
reliable
installation
and
to
minimize
signal
or
power
loss.
6.
Think
before
you
drill!
Be
careful
not
to
cut
or
drill
into
gas
tanks,
fuel
lines,
brake
or
hydraulic
lines,
vacuum
lines
or
electrical
wiring
when
working
on
any
vehicle
.
7.
Never
run
wires
underneath
th
e
vehicle.
Running
t
he
wires
inside
the
vehicle
provides
the
best
protection.
8.
Avoid
running
wires
over
or
through
sharp
edges.
Use
rubber
or
plas
ti
c
grommets
to
protect
any
wires
routed
through
metal,
especially
the
firewall.
9.
ALWAYS
protect
the
battery
and
electrical
system
fr
om
damage
with
proper
fusing
.
Install
the
appropriate
fuse
holder
and
fuse
on
the+
12V
power
wire
within
18"
(457
em
)
of
the
battery
term
i
nal.
10.
When
grounding
to
the
chassis
of
the
vehicle,
scrape
all
paint
from
the
metal
to
ensure
a
good
,
clean
ground
connec
ti
on.
Grounding
connections
should
be
as
short
as
possible
and
always
be
connected
to
metal
that
is
welded
to
the
main
body,
or
chassis
,
of
the
vehicle.
Seatbelt
bolts
should
never
be
used
for
connecting
to
ground
.
Mounting
Locations
Engine
Compartment
Never
mount
this
unit
in
the
eng
i
ne
compartment.
Mounting
the
unit
in
the
engine
compartment
will
void
y
ou
r
warranty.
Trunk
Mounting
Mounting
the
amplifier
vertically
or
inverted
will
provide
adequate
cool-
ing
of
the
amplifier.
Mounting
the
amplifier
on
the
floor
of
the
trunk
will
provide
the
best
cooling
of
the
amplifier.
Passenger
Compartment
Mounting
Mounting
the
amplifier
in
the
passenger
compartment
wi
ll
work
as
long
as
you
provide
a
sufficient
amount
of
air
for
the
amplifier
to
cool
its
e
lf.
If
you
are
going
to
mount
the
amplifier
under
the
seat
of
the
vehicle,
you
must
have
at
least
1"
(2
.
54cm)
of
air
gap
around
the
amplifier's
heats
ink.
Mounting
the
amplifier
with
les
s
than
1"
(2
.
54cm)
of
air
gap
around
the
amplifie
r's
heatsink
in
the
pass
en
ger
compartment
wi
ll
not
provide
proper
cooling
and
will
severely
affect
th
e
performance
of
the
amplifier
and
is
strongly
not
recommended.
Battery
and
Charging
Amplifiers
will
put
an
increased
load
on
the
vehicle
's
batte
ry
and
charging
system
.
We
recommend
checking
your
alternator
and
battery
condition
to
ensure
that
the
electrical
system
has
enough
capacity
to
handle
the
increased
load
of
your
stereo
sys
tem
.
Stock
electrical
systems
which
are
in
good
condition
should
be
ab
le
to
handle
the
extra
load
of
any
Prime
Series
amp
l
ifier
without
probl
e
ms
,
although
battery
and
alternator
life
can
be
reduced
slightly.
To
maximi
ze
t
he
performance
of
your
amplifier
,
we
suggest
the
use
of
a
heavy
duty
battery
and
an
energy
storage
capacitor.

~CAUTION
Avoid
running

1.
Plan
the
wire

.
Keep
RCA
cables
close
together
but
isola
t
ed
from
the
amp
I
ifier's
power
cables
and
any
high
power
auto

s,
especially
electric

This
is
done
to
prevent
coupling
the

se
from
radiated
electrical
fields
into
the
audio
signal.
When
fee
d
ing
the
wires
through
the
firewall
or
any
metal
barrier,
protect
them
with
plastic
or
rubber
gr
ommets
to
prevent
short
circuits.
Leave
the
wires
long
at
this
point
to
adjust
for
a
pr
e
cise
fit
at
a
later
time.
2.
Prepare

by
stripping
1/2"
of
insulation
from

If
POWER
light
is
on
skip
to
Step
3,
if
not
continue.
1.
Check

fuse
on
battery
positive
cable.
Replace
if
necessary.
2.
Check
fuse(s)
on
amplifier
.
Replace
if
necessary.
3.
Verify
that
Ground
connection
is
connected
to
clean
metal
on
the
vehicle's

.
Repair/replace
if
necessary.
4.
Verify
there
is
9
to
14.4
Volts
present
at
the
positive
battery
and
remote
turn-on
cable.
Verify
quality

.
1.
If
the
Protect
light
is
on,
this
is
a
sign
of
a
possible
short

connections.
Check
for
proper
speaker
connections
and
use
a
voiVohm
meter
to
check
for
possible
shorts
in
the
speaker
wiring.
Too
low
of
a
speaker
impedance
may
also
cause

output.
1.
Verify
good

etc.
Test
RCA
inputs
for
AC
volts
with
stereo
on.
Repair/replace
if
necessary.
2.
Disconnect
RCA

from
test
stereo
directly
to
amplifier
input.
Step
4.
Check
Amplifier
if
you
experience
Turn-on
Pop
.
1.
Disconnect
input
signal

is
eliminated
,
connect
the
REMOTE

turn-on
module
.
OR
1.
Use
a
different
12
Volt
source
for
REMOTE
lead
of
amplifier.
Troubleshooting
Step
5.
Check
