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 Power 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
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.
NOTE:We recommend a 4 AWG wire for use on the power (B+) and ground (GND) connections.
2.Prepare the RED wire (power cable) for attachment to the amplifier by stripping 5/8" 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 a large 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 5/8" 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
NOTE:Keep the length of the BLACK wire (Ground) as short as possible. Always less than 30"(76.2cm).
