NSTALLATION

BATTERY AND CHARGING

This amplifier will draw a maximum of 350 - 375 Amps of current. Therefore for 'street' it is recommended to use a minimum of 2
additional batteries, as well as a high output alternator. These requirements do not change for competition use, as the amplifier will
deliver the same amount of burst output power as long as the battery voltage is maintained between 11.0V and 15.5V. Running
excessive battery voltage for a competition vehicle is pointless with the T15kW.

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: 1/0 AWG wire for power and ground connections is required.
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 pre-
vent 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 termi-
nal 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 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 for attachment to the amplifier by stripping 5/8" 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. Use the mounting brackets and hardware supplied and securely mount the amplifier to the vehicle. DO NOT mount the amplifier
on cardboard or plastic panels.The place where you mount must be able to handle the weight of the amplifier through vibration,
bumps or sudden vehicle stops.
8. Connect from source signal by plugging the RCA cables into the input jacks at the amplifier.
CAUTION: Always ensure power is off or disconnected at the amplifier before connecting RCA cables. Failure to
do so may cause injury, damage to the amplifier and/or connected components.
