Installation Considerations
The following is a list of tools needed for installation:
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.
If you feel unsure about installing this sys-
tem yourself, have it installed by a qualified
technician.
Before installation, disconnect the battery neg-
ative (-) terminal to prevent damage to the unit,
fire and/or possible injury.
Before beginning any installation, follow these simple rules:
1. Be sure to carefully read 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 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.

Grounding Wire
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
vehicle 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 cm) 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.
Amplifier Centering Indicators
Centering indicators have been incorporated into the amplifier’s
heatsink to aid in the installation process.
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 provide 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 heat sink.
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 ensure that the electrical system has enough capacity to handle the
increased load of your stereo system. Stock electrical systems which are
in good condition should be able to handle the extra load of any Prime
Series amplifier without problems, although battery and alternator life can
be reduced slightly. To maximize the performance of your amplifier, we
suggest the use of a heavy duty battery and an energy storage capacitor.
Installation Installation
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.
NOTE: When utilizing high-level for input signal the auto turn-on feature
is active. With the auto turn-on active, the REM becomes an output to turn
on/off up to two additional amplifiers or other accessories.
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 into the RCA input jacks
at the amplifier. The input sensitivity ranges from 150mV-12V
to accommodate signal from either high-level(speaker) to low-
level(RCA).
NOTE: All “ACTIVE” inputs must have RCA jacks connected. Switch in
2CH. position,“ACTIVE” - Front channel inputs only. Switch in 4CH.
position,“ACTIVE” - All Front and Rear channel inputs. Switch in FRONT.
position,“ACTIVE” - Front channel inputs only for sub output. Switch in
SUB position,“ACTIVE” - Sub inputs for sub output. When connecting
to the 5-Channel inputs, be sure to route front, rear and sub RCA cables
tightly together.
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.
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 signal polarity.
This amplifier is not recommended for im-
pedance loads below 2-Ohm stereo/4-Ohm
bridged for the multi-channel amplifiers and
1-ohm for mono amplifiers.
Wiring the System
If you do not feel comfortable with wiring your
new unit, please see your local Authorized
Rockford Fosgate Dealer for installation.
Before installation, disconnect the battery neg-
ative (-) terminal to prevent damage to the unit,
fire and/or possible injury.
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 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 fuse holder 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 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 amplifier
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 possible.
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 place. Connect the other end of the Remote wire to a switched
12 volt positive source. The switched voltage is usually taken from the
