NSTALLATION
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 Power Series amplifier without problems, although battery
and alternator life can be reduced slightly.To maximize the performance of your amplifier, we suggest the
use of a heavy duty battery and an energy storage capacitor.
WIRING THE SYSTEM
CAUTION
: If you do not feel comfortable with wiring your new unit, please see your
local Authorized Rockford Fosgate Dealer for installation.
CAUTION
: Before installation, disconnect the battery negative (-) terminal to prevent
damage to the unit, fire and/or possible injury.
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.
NOTE:
Use the Allen wrench provided to tighten the power and speaker terminals.
1. Plan the wire routing. Keep RCA cables 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.
NOTE:
We recommend a 1/0 AWG wire for use on the power (B+) and ground (GND) connections.
2. Prepare the RED wire (power cable) for attachment to the amplifier by stripping 7/8" 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 ensure connections are water tight.
3. Trim the RED wire (power cable) within 18" of the battery and splice in a inline fuse holder. See
Specifications for the rating of the fuse to be used. DO NOT install the fuse at this time.
4. Strip 1/2" 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.
5. Prepare the BLACK wire (Ground cable) for attachment to the amplifier by stripping 7/8" of
insulation from the end of the wire. Insert the bare wire into the GROUND terminal and tighten the
set screw to secure the cable in place. Prepare the chassis ground by scraping any paint from the
metal surface and thoroughly clean the area of all dirt and grease. Strip the other end of the wire and
attach a ring connector. Fasten the cable to the chassis using a non-anodized screw and a star washer.
NOTE:
Keep the length of the BLACK wire (Ground) as short as possible.Always
less than 30"(76.2cm).
6. Prepare the Remote turn-on wire for attachment to the amplifier by stripping
7/8" of insulation from the end of the wire. Insert the bared wire into the
REMOTE terminal and tighten the set screw to secure the wire in place.
Connect the other end of the Remote wire to a
switched 12 volt positive source.The switched
voltage is usually taken from the source unit's
remote amp on lead. If the source unit does not
have this output available, the recommended
solution is to wire a mechanical switch in line
with a 12 volt source to activate the amplifier.
7. Securely mount the amplifier to the vehicle or
amp rack. Be careful not to mount the amplifier
on cardboard or plastic panels. Doing so may
enable the screws to pull out from the panel due
to road vibration or sudden vehicle stops.
