specifications for fuse rating)
• Hand held drill w/assorted bits
• Volt/Ohm Meter

Grounding Wire
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 ac cessible for making
adjustments.
If you feel unsure about installing this system yourself, have it installed by
a qualified technician .
.6.CAUTION Before installation, disconnect the battery neg-
ative (-)terminal to prevent damage to the unit,
fire and/or poss i ble injury.
Lt. CAUTION
Before beginning any installation, follow these
simple rules :
1.
Be sure to carefully re ad and understand the instructions before
attempting to install the unit.
2. For safety, disconnect the negative lead from the battery prior to
beginning the installation .
3. For easier assembly, we suggest you run a ll 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 connec t ors 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 the vehicle . Running the wires inside the
vehic le provides the best protection.
8. Avoid running wires over or through sharp edges. Use rubber or
plastic grommets to protect any wires routed through metal, especially
the firewall.
9. ALWAYS protect the battery and electrical system from damage with
proper fusing. Install the appropriate fuse holder and fuse on the+ 12V
power wire within 18" (45.7 em) of the battery terminal.
10. When grounding to the chassis of the vehicle, scrape all 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 main body, or chassis , of the vehicle .
Seatbelt bolts should never be used for connecting to ground.
Mounting Locations
To ensure optimal performance , mount the amplifier with at least
1" (2.54cm) of air gap around the amplifier's heat sink to provide
proper cooling.
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 will work as long as
you prov i de a sufficient amount of air for the amplifier to cool itself. 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.
A-- CAUTION Never mount this unit in the engine compart-
~ ment. Mounting the unit in the engine com-
partment will void your warranty.
Battery and Charging
Amplifiers will put an increased load on the vehicle's battery and charging
system. We recommend checking your alternator and battery condition
to en s ure that the electri c al s ystem has enough capacity to handle the
increased load of your stereo system . Stock e lectrical systems which are
in good condition should be abl e to handle the extra load of any Prime
Series amplifier without proble ms, a lthough battery and altern a tor life can
be reduced slightly. To maximize the pe rformance of your amplifier, we
s uggest t he use of a heavy duty battery and an en e rgy storage capacitor.

Lt.
CAUTION
If
you
do
not
feel
comfortable
with
wiring
your
new
unit,
please
see
your
local
Authorized
Rockford
Fosgate
Dealer
for
installation
.
Lt_
CAUTION
Before
installation,
disconnect
the
battery
neg-
ative
(-)terminal
to
prevent
damage
to
the
unit,

and/or
possible
injury.
Lt_
CAUTION
Avoid
running

wires
near
the

power
leads,
sensitive
equipment
or
harnesses
.
The
power
wires

could

into
the
audio
system.
1.
Plan
the
wire
routing.
Keep
RCA
cables
close
together
but
isolated
from
the
amplifier'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
in
line
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
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
ampli
f
ier
by
stripping
1/2"
of
insulation
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
poss
i
ble.
Always
less
than
30"
.

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
pl
ace.
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.
If
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
pane
ls.
Doing
so
may
enable
the
screws
to
pull
out
from
the
panel
due
to
road
vibration
or
sudden
vehicle
stops.
8.
Connect
from

by
plugging
the
