Installation Considerations The following is a list of tools needed for installation:

Wire
Turn-on Wire
Grounding Wire

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.

CAUTION If you feel unsure about installing this system yourself, have it installed by a qualified technician.

CAUTION 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.

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, clear 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. Seatbell 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 healsink to aid in the installation process.

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 seal of the vehicle, you must have at least 1° (2.54cm) of air gap around the amplifier's heat sink.

CAUTION 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

Wiring the System

CAUTION If you do not feel comfortable with wiring your new unit, please see your local Authorized Rockford Fosgate Dealer for installation.

CAUTION Before installation, disconnect the battery negative (-) terminal to prevent damage to the unit, fire and/or possible injury.

CAUTION 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 leading the wires through the firewall or any metal barrier, protect them with plastic or rubber grammels to prevent short circuits. I have the wires long at this point to adjust for a precise hit at a later time.

2. Prepare the RLD wire (power cable) for attachment to the amplifier by stripping 1/2" of insulation from the end of the wire. Insert the band 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.

1. Trim the RED wire (power cable) within 18 ^st 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.

2. Strip 1/2" from the battery end of the power cable and crimp an appropriate side ring terminal to the cable. Use the ring terminal to connect to the battery positive terminal.

3. 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 lighton the soil screw to secure the cable in place. Prepare the chassis ground by scraping any paint from the motor 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-analyzed screw and a star washer. NOTE: Keep the length of the BLACK wire (Ground) as short as possible. Always less than 30".

4. Prepare the Remote turn-on wire for attachment to the amplifier by stripping 1/2" of Insulation from the end or the wire. Insert the bared wire into the REMOTE terminal and lighten the set screw to secure the wire in place. Connect the other end of the Remote wire to a switched 12 volt positive scumba. The switched voltage is usually taken from the

source unit's remote amp on load. 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.

1. Securely mount the amplifier to the vehicle or ramp 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.

2. 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 other high-level(speaker) to low-level(RCA).

NOTE: All 'ACTIVE' inputs must have RCA jacks connected. Switch in 2CHL position, "ACTIVE" - Front channel inputs only. Switch in 4CHL position, "ACTIVE" - All Front and Rear channel inputs. Switch in FRONT position, "ACTIVE" - Front channel inputs only for sub cutout. 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 lightly together.

CAUTION 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.

1. 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. DC NOT chassis ground any of the speaker leads as unstable operation may result.

2. 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.

CAUTION This amplifier is not recommended for impedance loads below 2-Ohm stereo/4-Ohm bridged for the multi-channel amplifiers and 1-ohm for mono amplifiers.

Operation Operation

Input Clip Indicator Setup

Step 1. Be sure to disconnect all speakers from the amplifier

CAUTION

Failure to comply may cause damage to connected components and/or amplifier.

Step 2. Turn on the source unit with volume set to zero.

Step 3. Adjust the Bass & Treble levels on the source unit to flat.

Step 4. Insert test tone or music CD to play for setup.

Note: Use the 40Hz @ 0dB tone (Track 5) for more amplifier applications or the 16 Hz @ 0dB tone (Track 7) for multi-channel amplifier applications. Be sure your x-over is switched to the appropriate filter setting.

Step 5. Increase the source unit volume until the Input Clip Indicator II-lumirales red

Note: Input Clip can be viewed remotely with optional PLC2.

Step 6. Decrease the source unit volume slightly until the light turns completely oil. This establishes your maximum source unit volume for adjusting the Output Clip Indicator.

Note. Some source units will not clip

Output Clip Indicator Setup

Step 7. Be sure to disconnect Punch Level Control - PLC (if equipped) from the amplifier.

Step 8. Adjust the Input Level knob until the Output Clip Indicator Illuminales to the appropriate solar. Repeat for all channel levels of Input.

Step 9. Turn the source unit volume down.

Step 10. Recognizes all speakers and Punch Level Control PLC (It equipped) to the amplifier. Be sure to maintain proper speaker polarity.

Adjusting Crossover Frequency

Do the following individually for each channel.

Placing the crossover switch in the HP

position sells 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.

2/4 Channel 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.

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

Subwoofer Input Switch (P1000X5)

Setting this switch to the On position, utilizes the front inputs, allowing connection to only the front inputs with a subcooler output. Setting this switch to the On position uses sub input.

Output controls function the same as if the amplifier was in 5-channel mode.

All "ACTIVE" inputs must have RCA jacks connected.

Switch in FRONT, position, "ACTIVE" - Front channel inputs only for sub output. Switch in SUB position, "ACTIVE" - Sub inputs for sub output.

NOTE: When connecting to the 5 Channel Inputs, be sure to route front, rear and sub RCA cables lightly together.

High Level Input

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 high-level(speaker) input. When utilizing high-level for input

signal the auto turn-on feature is active. With the auto turn-on active, the RFM becomes an output to turn on/off up to two additional amplifiers or other accessories.

Pass Thru

The pass-thru RCA's are passive, including full input signal range and auto turn-on functionality when active. When utilizing Pass Thru jacks, up to two additional amplifiers can be connected together.

Inlasonic Filter

The 28Hz 12dB/octave intrasonic filter limits the amount of low frequency information going to the wacker.

NOTE: We recommend using the infrasonic filter when using vented enclosures with this amplifier.

Punch EQ

This works along with the crossover switch on the amplifier. When set to Low-Pass (LF) operation, this is a variable Bass Boost. When set to High-Pass (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.

CAUTION

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

Remote Punch Level Control (Option)

NOTE: Previous(prior to 2013) FEQ, PunchBassandPara-Punch remoles will not work with these amplifiers.

Quick Install:

1. Using the screws supplied, install the mounting clip

Troubleshooting

NOTE: If you are having problems after installation follow the Troubleshooting procedures below.

Check Amplifier for proper connections. Verify that POWER light is on. If POWER light is on skip to Step 3, if not continue.

1. Check in-line luse on battery positive cable. Replace if necessary.
2. Check fuse(s) on amplifier. Replace if necessary.
3. Verify that Ground connection is connected to clean metal on the vehicle's chassis. Repair/replace if necessary.
4. Verify there is 9 to 14.4 Volts present at the positive battery and remote turn-on cable. Verify quality corrections for both cables at amplifier, stereo, and battery/tusenolter. Repair/replace if necessary. Protect light is on.
5. If the Protect light is on, this is a sign of a possible short in the speaker connections. Check for proper speaker connections and use a bell/chim melor to check for possible shorts in the speaker wiring. Too low of a speaker impedance may also cause Protect to light.
6. Verify good RCA input connections at stereo and amplifier. Check entire length of cables for kinks, splices, etc. Test RCA inputs for AC volts with stereo on. Repair/replace if necessary.
7. Disconnect RCA input from amplifier. Connect RCA input from test stereo directly to amplifier input.

Check Amplifier for audio output.

Check Amplifier if you experience Turn-on Pop.

1. Disconnect input signal to amplifier and turn amplifier on and off.
2. If the noise is eliminated, connect the REMOTE lead of amplifier to source unit with a delay turn-on module.
