will
be
easily
accessible
for
making
adjustments.

protec
t
any
wires
routed
through
metal,
especially

9.
ALWAYS
protect
the

to
the
chassis
of
the
vehicle
,
scrape
a
ll
paint
from
the
metal
to
ensure
a
good
,
clean
ground
connection.
Grounding
connections
should
be
as
short
as
possible
and
always
be
connected
to
metal
that
is
welded
to
the

Mounting
Locations
To
ensure
optimal
performance
,
mount
the
amplifier
with
at
least
1"
(2.54cm)
of
air

around
the
amplifier's
heat
sink
to
provide
proper
cooling.

6CAUTION
If
you
do
not
feel
comfortable
with
wiring
your
new
unit,
please
see
your
local
Authorized
Lightning
Audio
Dealer
for
installation.
6 CAUTION
Before
installation,
disconnect
the
battery
neg-
ative(-)
terminal
to
prevent
damage
to
the
unit,
fire
and/or
possible
injury.
6CAUTION
Avoid
running
power
wires
near
the
low
level
input
cables
,
antenna
,
power
leads,
sensitive
equipment
or
harnesses
.
The
power
wires
car-
ry
substantial
current
and
could
induce
noise
into
the
audio
system.
1.
Plan
the
wire
routing.
Keep
RCA
cables
close
together
but
isolated
from
the
amp
I
ifier
's
power
cables
and
any
high
power
auto
accessories,
especially
electric
motors
.
This
is
done
to
prevent
coupling
the
noise
from
radiated
electrical
fields
into
the
audio
signal.
When
feeding
the
wires
through
the
firewall
or
any
metal
barrier,
protect
them
with
plastic
or
rubber
grommets
to
prevent
short
circuits
.
Leave
the
wires
long
at
this
point
to
adjust
for
a
precise
fit
at
a
later
time.
2.
Prepare
the
RED
wire
(power
cable)
for
attachment
to
the
amplifier
by
stripping
1/2"
of
insulation
from
the
end
of
the
wire.
Insert
the
bared
wire
into
the
B+
terminal
and
tighten
the
set
screw
to
secure
the
cable
in
place.
NOTE:
The
B+
cable
MUST
be
fused
18"
or
less
from
the
vehicle's
battery.
Install
the
fuseholder
under
the
hood
and
ensure
connections
are
water
tight.
3.
Trim
the
RED
wire
(power
cable)
within
18"
of
the
battery
and
splice
in
a
inline
fuse
holder
(not
supplied).
See
Specifications
for
the
rating
of
the
fuse
to
be
used.
DO
NOT
install
the
fuse
at
this
time.
4.
Strip
1/2"
from
the
battery
end
of
the
power
cable
and
crimp
an
appropriate
size
ri
ng
terminal
to
the
cable
.
Use
the
ring
terminal
to
connect
to
the
battery
positive
terminal.
5.
Prepare
the
BLACK
wire
(Ground
cable)
for
attachment
to
the
amplifier
by
s
tripping
1/
2"
of
in
s
ulation
from
the
end
of
the
wire.
Insert
the
bare
wire
into
the
GROUND
terminal
and
tighten
the
set
screw
to
secure
the
cable
in
place
.
Prepare
the
chassis
ground
by
scraping
any
paint
from
the
metal
surface
and
thoroughly
clean
the
area
of
all
dirt
and
grease
.
Strip
the
other
end
of
the
wire
and
attach
a
ring
connector.
Fasten
the
cable
to
the
chassis
using
a
non
-
anodized
screw
and
a
star
washer.
NOTE
:
Keep
the
length
of
the
BLACK
wire
(Ground)
as
short
as
possible
.
Always
less
than
30".

INSTALLATION
6.
Prepare
the
Remote
turn-on
wire
for
attachment
to
the
amplifier
by
stripping
1/2"
of
insulation
from
the
end
of
the
wire
.
Insert
the
bared
wire
into
the
REMOTE
terminal
and
tighten
the
set
screw
to
secure
the
wire
in
place.
Connect
the
other
end
of
the
Remote
wire
to
a
switched
12
volt
positive
source
.
The
switched
voltage
is
usually
taken
from
the
source
unit's
remote
amp
on
lead.lf
the
source
unit
does
not
have
this
output
available,
the
recommended
solution
is
to
wire
a
mechanical
switch
in
line
with
a
12
volt
source
to
activate
the
amplifier.
7.
Securely
mount
the
amplifier
to
the
vehicle
or
amp
rack
.
Be
careful
not
to
mount
the
amplifier
on
cardboard
or
plastic
panels
.
Doing
so
may
enable
the
screws
to
pull
out
from
the
panel
due
to
road
vibration
or
sudden
vehicle
stops.
8.
Connect
from
source
signal
by
plugging
the
RCA
cables
into
the
input
jacks
at
the
amplifier.
NOTE:
All
"ACTIVE"
inputs
must
have
RCA
jacks
connected.
When
con-
necting
to
the
5-Channel
inputs,
be
sure
to
route
front
,
rear
and
sub
RCA
cables
tightly
together.
Lt._
CAUTION
Always
ensure
power
is
off
or
disconnected
at
the
amplifier
before
connecting
RCA
cables
.
Failure
to
do
so
may
cause
damage
to
the
am-
plifier
and/or
connected
components.
Note:
When
the
installation
requires
a
High
Level
(Speaker)
input,
use
the
included
connector
to
tie
into
your
vehicles
speaker
wiring
.
9.
Connect
the
speakers.
Strip
the
speaker
wires
1/2"
and
insert
into
the
speaker
terminal
and
tighten
the
set
screw
to
secure
into
place
.
Be
sure
to
maintain
proper
speaker
polarity
.
DO
NOT
chassis
ground
any
of
the
speaker
leads
as
unstable
operation
may
result.
10.
Perform
a
final
check
of
the
completed
system
wiring
to
ensure
that
all
·
connections
are
accurate.
Check
all
power
and
ground
connections
for
frayed
wires
and
loose
connections
which
could
cause
problems.
Install
inline
fuse
near
battery
connection.
NOTE:
Follow
the
diagrams
for
proper
