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.
•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. | X |
|
Trim the power cable within 18" of the battery and | Cut | |
here | ||
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. |
