Installation
Power Connector
The power connector allows for quick connec-
tion and disconnection of the amplifier’s Re-
mote, power and ground source. The power and
ground are set-screw wire connectors and will
accommodate 4 AWG. The remote is a set-screw
wire connector and will accommodate 8 AWG.
Phase Switch
Allows you to select the output phase of
the amplifier between 0° and 180°.
Input Level
Set the Input Level switch to match the outputs of your
source unit.(LO - RCA or HI - Speaker Level)
Auto Turn On
Three different automatic turn-on modes can be se-
lected; REM(+12V), DC Offset and Audio.
Variable Crossover
Is a built-in 12dB/octave Butterworth filter with
a crossover point variable from 50Hz to 120Hz.
Punch EQ
This is an adjustable Bass control adjustment vari-
able from 0dB to +12dB @ 45Hz.
Power/Protect LED
Power LED illuminates green
when the unit is turned on.
Protect LED illuminates red
if a short circuit or to low of
an impedance is detected at
the speaker connections.
The amplifier will automati-
cally shut down if this oc-
curs.
Remote Punch Level Control
When connected, the “Level Control” is linked
and allows you to remotely control the output
level of the amplifier from the dash or center
console.
Audio Input
The RCA/Speaker Harness utilizes either speaker
level (high-level) or RCA (low-level) inputs.
Input Level Control
The input level control is used to match the
output of the audio source.

Installation Considerations
The following is a list of tools needed for installation:
This section focuses on some of the vehicle considerations for installing
your new powered loaded enclsoure. 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 system 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.
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.
• Volt/Ohm Meter
• Wire strippers
• Wire crimpers
• Wire cutters
• #2 Phillips screwdriver
• Battery post wrench
• Hand held drill w/assorted bits
• Assorted connectors
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
Trunk or Passenger Compartment Mounting
Choose a structurally sound location to mount your powered loaded en-
closure. Mount the enclosure in such a manner that the amplifier has a
minimum of 1” (2.54cm) of air gap around the amplifier’s heatsink to pro-
vide proper cooling to ensure optimum performance of the amplifier is
strongly recommended.
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.
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.
