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.
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 attach-
ment 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 installa-
tion of the end caps. Proper wire
dress can prevent this from occur-
ring. 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.
