Rockford Fosgate 40ix - Manual (Page 14)

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, high output alternator 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 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+ 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.
