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 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 system yourself, have it installed by
a qualified technician.

Before installation, disconnect the battery neg­ative (-) 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.

specifications for fuse rating)

•Volt/Ohm Meter

•Wire strippers

•Wire crimpers

GroundingWire

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.

Trunk Mounting

Mounting the amplifier vertically or inverted will provide adequate cool­ing 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 heatsink.

Never mount this unit in the engine compart­ment. Mounting the unit in the engine com­partment 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

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 neg­ative (-) 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 car­ry 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 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 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
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 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. Switch in
2CH. position,“ACTIVE” - Front channel inputs only. Switch in 4CH.
position,“ACTIVE” - All Front and Rear channel inputs. Switch in 5CH
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 am­plifier and/or connected components.

Note: When the installation requires a High Level (Speaker) input, use the
4-pin Molex 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 signal polarity.

This amplifier is not recommended for im­pedance loads below 2-Ohm stereo/4-Ohm
bridged for the front/rear channels and 2-ohm
for the sub channel. Models R750-1D and
R1200-1D are not recommended for imped­ance loads below 1-Ohm.

Adjusting Gain

1. Turn amplifier gains to minimum (counter-clockwise).

2. Turn the source unit volume up to 7/8 maximum (or when
distortion is just inaudible).

3. Slowly increase amplifier gain control until adequate volume is
achieved.

NOTE: Best signal to noise and dynamic range are realized with gain set
to minimum. For a more in depth setting procedure, contact Rockford
Technical Support.

Avoid setting amplifier gain high as noise and
distortion will greatly increase.

Adjusting Crossover Frequency

Do the following individually for each channel.
Placing the crossover switch in the HP posi-

tion sets the amplifier to the High Pass mode,
enabling frequencies above the cut-off point to
pass, adjustable between 50-250Hz.

Placing the crossover switch in the AP position sets the amplifier to the All
Pass mode, preventing any crossover adjustment, allowing all frequencies
to pass.

Placing the crossover switch in the LP position sets the amplifier to the
Low Pass mode, enabling frequencies below the cut-off point to pass,
adjustable between 50-250Hz.

Turn the crossover adjustment knob all the way down. With the system
playing, turn the crossover adjustment knob up slowly until the desired
crossover point is achieved.

Input Switch

Setting this switch to the 2CH. position, switches the
inputs to a 2-channel mode, allowing connection to only
the front inputs with a 4-channel output.

Output controls function the same as if the amplifier was in 4-channel
mode.

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 5CH. position,“ACTIVE” - All Front, Rear and Sub channel
inputs.

NOTE: When connecting to the 4-Channel inputs, be sure to route both
front and rear RCA cables tightly together.

Variable Phase

Allows you to conveniently switch the output phase of the
amplifier between 0° and 180°. This has the same effect as
physically reversing the Positive (+) and Negative (-) speaker wires.

High Level Input

High Level Inputs are used when you want to connect an amplifier to your
factory radio or an aftermarket radio that does not have low-level (RCA)
inputs. It allows you to use the signal coming from the speaker outputs as
an input source for the amplifier.

Punch EQ

This works along with the crossover switch on the amplifier. When set to
Low-Pass (LP) operation, this is a variable Bass Boost. When set to High­Pass (HP) operation, this is a variable Mid-Bass and Treble Boost. When
set to All-Pass (AP) operation, both the Bass and Treble frequencies are
boosted. Set this to your personal preference while listening to the system.

Variable 0-+18dB @ 45Hz (R400-4D, R600-4D, R750-1D & R1200-1D)

Variable 0-+12dB @ 45Hz (R150X2, R250X1, R500X1D & R600X5)

Selectable: 0/+6dB/+12dB @ 45Hz (R250X4, R300X4 & R600X5)

Over excursion and subsequent damage may
occur at high levels of boost.
