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

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
