BASSLINK 4SC INSTALLATION
This owner’s manual assumes BassLink II is
installed in your vehicle. If you are installing
both units simultaneously, refer to the BassLink II
owner’s manual for instructions regarding the
mounting of BassLink II and the REMOTE LEVEL
control, and to this owner’s manual for tuning.
DESCRIPTION
The BassLink 4sc is a four-channel plug-and-play
amplifier designed to make upgrading your
system easy. The BassLink 4sc is designed to
slide into an available slot in the BassLink II. The
BassLink 4sc also includes a Phantom Center
circuit, which creates the illusion of a center
channel without requiring a center speaker.
INSTALLATION
1. Disconnect BassLink II’s power connection
from the battery.
2. Remove the wiring cover from BassLink II.
3. Remove, but do not discard, the eight screws
that hold the AMPLIFIER DOCK cover panel in
place (Figure 1).
4. Remove and discard the screw that attaches
the two wiring harnesses and connectors to
the dock cover.
5. Slide the 4sc amplifier partially into the
opening and connect the wiring harness
connectors to the appropriate connectors on
the BassLink 4sc’s circuit board (Figure 2).
6. Insert the amplifier and secure it using the
eight screws that were removed in Step 3
(Figure 2). Extra screws have been included
with the 4sc.
7. Upgrade the fuse at the vehicle’s battery
(installed with BassLink II) to a 50A fuse.
8. Reconnect battery power lead.
