INSTALLATION

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.

Mounting the amplifier with less than 1" (2.54cm) of air gap around the amplifier's heatsink in the passenger compartment will not provide proper cooling and will severely affect the performance of the amplifier and is strongly not 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

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 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 3/8" of insulation from the end of the wire. Crimp the bared wire into a fork or ring style connector and attach to the B+ terminal.Tighten the 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 3/8" of insulation from the end of the wire. Crimp the bared wire into a fork or ring style connector and attach to the GROUND terminal.Tighten the 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"(76.2cm).

6.Prepare the Remote turn-on wire for attachment to the amplifier by stripping 3/8" of insulation from the end of the wire. Crimp the bared wire into a fork or ring style connector and attach to the REMOTE terminal.Tighten the 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.
