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 sub-
stantial 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 firewall or
any metal barrier, protect them with plastic or rubber grommets to pre-
vent short circuits. Leave the wires long at this point to adjust for a pre-
cise fit at a later time.
2. Prepare the
Power cable for attachment
to the amplifier by stripping 5/8" of insu-
lation 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 fray-
ing, strip the insulation 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.
3. Strip 3/8" 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.
Do not install the fuse at this time.
