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.
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.
2. Prepare the RED wire (power cable) for attachment to the amplifier by stripping 5/8" 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 5/8" of insulation from the end of
the wire. Insert the bare wire into the GND 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 REM turn-on wire for for attachment to the amplifier by stripping 5/8" of insulation from
the end of the wire. Insert the bared wire into the REM terminal and tighten the set screw to secure
the wire in place. Connect the other end of the REM 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.
8. Connect from source signal by plugging the RCA cables into the input jacks at the amplifier.
9. Connect the speakers. Strip the speaker wires 1/2" and insert into the speaker terminal and tighten
the set screw to secure into place. Be sure to maintain proper speaker polarity. DO NOT chassis
ground any of the speaker leads as unstable operation may result.
10. Perform a final check of the completed system wiring to ensure that all connections are accurate.
Check all power and ground connections for frayed wires and loose connections which could cause
problems. Install inline fuse near battery connection.
NOTE:Follow the diagrams for proper signal polarity.
