Battery And Charging; Wiring The System - Rockford Fosgate PUNCH 40.2 Operations & Installation Manual

B
ATTERY AND
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 Rockford amplifier without problems,
although battery and alternator life can be reduced slightly. To
maximize the performance of your Rockford Fosgate amplifier, we
suggest the use of a heavy duty battery and an energy storage
capacitor.

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.
• For safety, disconnect the negative lead from the battery prior to
beginning the installation.
1. Configure the internal XCard crossovers prior to installation. Refer
to "Using the XCard" (page 14) for further information.
2. Plan the wire routing. Take care when running signal level RCA
cables to keep them 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.
3. Prepare the Power cable for at-
tachment to the amplifier by strip-
ping 5/8" of insulation from the
end of the wire. To prevent the
wire from fraying, strip the insula-
tion at a 45° angle. Insert the bared
wire into the B+ terminal with the
long side of the insulation on the
top. Bend the cable down at a 90°
angle. Tighten the set screw to secure the cable in place.
