INTRODUCTION THANK YOU for choosing the Infinity BassLink II powered subwoofer. BassLink II has been designed to provide the kind of high-performance lowfrequency reproduction that used to require big, clumsy enclosures, large amplifiers and complex installation. To ensure maximum performance, we strongly recommend that installation be entrusted to a qualified professional.
POWER CONNECTIONS Make Power, Ground and Remote Turn-On connections as shown in Figure 5. Observe the following installation tips: • Use #8 AWG wire for the +BATT (+12Vdc) and GND (ground) connections. If needed, use at least a #20 AWG wire for the REM (remote) connection. • If you pass the power or remote wire through the vehicle’s firewall or other metal obstruction, it must be insulated with a rubber grommet.
APPLICATIONS (CONTINUED) Figure 7. BassLink II audio connections for a head unit equipped with four line-level (RCA) outputs. Figure 8. BassLink II audio connections for a head unit equipped with four speaker-level outputs.
BASSLINK 4SC INSTALLATION APPLICATION Figure 9. INSTALLATION 1. Remove the wiring cover from BassLink II. 2. Remove the eight screws that hold the AMPLIFIER DOCK cover panel in place (Figure 9). Save the screws. 3. Remove the screw that attaches the two wiring harnesses and connectors to the panel. 4. Connect the wiring harness connectors to the appropriate connectors on the BassLink 4sc’s circuit board. See Figure 10. 5. Insert the amplifier and install the eight screws that were removed in Step 2.
CONTROLS AND FUNCTIONS BassLink II provides several controls and indicators that simplify sonic integration with virtually any vehicle’s unique acoustic properties. They are located on the front and side panels, as shown in Figures 14 and 15. TUNING BASSLINK II Figure 15. BassLink II controls on right-side panel. 2. Make sure the head unit is off and its volume control is set to minimum. Figure 14. BassLink II controls on the front panel.
