NOTE: Keep the length of the BLACK wire (Ground) as short as
possible. Always less than 30”.
NOTE: Skip step 6 if you are using Auto Turn ON feature.
6. Prepare the Remote turn-on wire for attachment to the amplifier
by stripping 1/2” 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.
Note: Skip step 8 if using High Level inputs.
8. Connect from source signal by plugging the RCA cables into the
input jacks at the amplifier.
NOTE: All “ACTIVE” inputs must have
RCA jacks connected. Switch in 2CH.
Position,“ACTIVE” - Front channel inputs
only. Switch in 4CH. Position,“ACTIVE”
- All Front and Rear channel inputs.
Switch in 5CH position,“ACTIVE” - Sub
inputs for sub output. When connecting
to the 5-Channel inputs, be sure to route
front, rear and sub RCA cables tightly
together.
Always ensure power is o or disconnected at the amplifier before
connecting RCA cables. Failure to do so may cause damage to the
amplifier and/or connected components.
9. If using High Level inputs, connect the OEM speaker wires
matching the positive and negative. If only using 1 input, be sure
to plug it into the front and make sure the input selection switch
is set to 2 ch.
10. 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. For mono amps, the two Positive (+) and Negative (–)
terminals are provided for installation flexibility. Both terminals
are wired in parallel internally. Only one Positive (+) and one
Negative (–) terminal is required for a speaker connection.
11. 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 in-line fuse near battery connection.
This amplifier is not recommended for impedance loads below
2-Ohm stereo/4-Ohm bridged for the front/rear channels and 2-Ohm
for the sub channel.
Installation
RLC Mounting Options – Utilize the included screws to secure the RLC
to the vehicle.
Wiring the System
If you do not feel comfortable with
wiring your new unit, please see your
local Authorized Rockford Fosgate
Dealer for installation.
Before installation, disconnect the
battery negative (-) terminal to prevent
damage to the unit, fire and/or possible
injury.
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 noise from radiated electrical fields into the audio
signal. When feeding the wires through the fire wall 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 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 fuse holder 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 in-line fuse holder (not supplied). 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 an
appropriate size 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 1/2” 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.
