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. 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.
2. Prepare the Power cable for attachment to the amplifier by stripping 1/
2" 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 prepare the cable
ends as stated above. Connections should be
water tight.
Trim the power cable within 18" of the battery and
strip 1/2" of insulation from the end of the wire. Cut
the wire loop that is attached to the fuseholder in
half and splice the fuse into the power line using
appropriate inline connectors. Use the section of
cable that was trimmed earlier and connect it to the
other end of the fuseholder.
