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

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"

recommended.
Battery
and
Charging
Amplifiers
will
put
an
increased
load
on
the
vehicle
's
batte
ry
and

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

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.

A\..l CAUTION Before installation, disconnect the battery neg-
~ alive (-)terminal to prevent damage to the un it,
fire and/or possible in jury.
~CAUTION
Avoid running pow er wires near the low level
input cables, antenna, power leads, sensit i ve
equipment or harnesses. The power wires car-
ry substantial current and could induce no i se
into the audio system.
1. Plan the wire routing . Keep RCA cables close together but isola t ed
from the amp I ifier's power cables and any high power auto accesso rie s,
especially electric motors. This is done to prevent coupling the no i 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 the RED wire (power cable) lor attachment to the ampli f ier by
stripping 1/2" of insulation from the end of the wire. Insert the bared
wire into the B+ terminal and tighten the se t screw to secure the cable
in place .
NOTE : The B+ cabl e MUST be fu se d 18" or less from the vehicle 's battery.
Install the fuseholder under the hood and ensure conn e ction s are water
tight.
3. Trim the RED wire (power cable) within 18 " of the battery and sp l ic e in
a inline fuse holder (not supplied) . See Sp e cifications for the rating of
the fus e to be used. DO NOT install the fuse at this tim e.
4. Strip 1/2" from the battery e nd of the power cabl ea nd crimp an
appropriate si ze ring 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 amp l if ier
by stripping 1/2" of insulation from the end of the wi re. Insert the bar e
wire into the GROUND terminal and tighten the s et s crew to secure the
cable in pla c e. Prepare the cha s si s ground by scraping any paint f rom
the metal surface and thoroughly clean the area of all dirt and grease.
Strip the other end of the wire and attach ar ing connector. Fasten the
cable to th e chassis using a non-anodized scr ewa nd a star washer.
NOTE: Ke ep th e length of the BLACK wire (Ground) ass hort as possib l e.
Always le ss than 3 0" .
6. Prepare the Remote turn-on wire for atta ch ment to the amplifier by
strippin g 1/ 2" of insulation from the end of the wire. Insert the bar ed
wire into the REMOTE terminal and tight enthe se t screw to secure t he
wire in place. Conn e ct th e other end of the Remote wire to a swit ch ed
12 volt po s itiv es ourc e. Th es wit c hed voltage is us ually taken from the
s ource unit's re mote a mp onle ad. If the sour ce unit does not have this
output ava il a bl e, th e recomm e nd ed soluti onis to wire a mechani ca l
swit ch in lin e with a 12 volt s ource to activ a te the a mplifier.
7. Securely mount the amplifier to the vehicle or a mp rack .Be careful not
to mount the amplifi er on cardboard or pla s tic panel s. Doing so may
e nable the screw s to pull out fr omthepanel du e to r oa d vibratio n or

8. Connect f rom source signal by pl ugging the RCA cables into the input
jacks at the amplifier.
NOTE: All " ACTIVE" inputs must have RCA jacks co nnected. Switch in

position, " ACTIVE"- All Front and Rear channel inputs . When connecting
to the 4-Cha n nel inputs, be sure to route both front and rear RCA cables
tightly together.
~CAUTION
Always ensure power is o ff or disconnected at
the ampli f ier before connecting RCA cables .
Failure to do so may cause damage to the am-
plifier and/or connected components.
9. Connect the speakers. Strip the speaker wires 1/2" and insert into the
speak er terminal and tigh ten the set screw to secure into place. Be
sure to maintain proper speaker polarity . DO NOT ch a ssis ground any
of the speaker leads as unstab le operation may resu l t.
10. Perform a final check of the completed system wiring to ensure that all
conne ctio ns are accurate . Check all power and ground connections
for frayed wires and loose connections which could cause problems.
Install in l ine fuse near battery connection .
NOTE: Follow the diagrams for pr o per signal polarity.
