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 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.
Wiring the System
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. 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 fire-
wall 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
Power cable for attachment to the amplifier by stripping
5/8" of insulation from the end of the wire. The use of 8 gauge power
cable can interfere with the installation of the end caps. Proper wire
dress can prevent this from occurring. To prevent the wire from fraying,
strip the insulation at a 45° angle. Insert the bared wire into the B+ ter-
minal 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.
