Never mount this unit in the engine compartment. Mounting the unit in the engine compartment will void
Mounting the amplifier vertically will provide adequate cooling of the amplifier.
Mounting the amplifier on the floor of the trunk will provide the best cooling of the amplifier.
Mounting the amplifier upside down to the rear deck of the trunk will not provide proper cooling and will
severely affect the performance of the amplifier and is strongly not recommended.
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 I" (2.54cm) of air gap around the amplifier's heatsink.
Mounting the amplifier with less than I" (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 Punch 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.
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
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.
