The specifications and details in this and related JBL publications are therefore subject to change without notice. 1 BassLink T POWER CONNECTIONS Connect power to BassLink T, as shown in Figure 6. Also observe these installation tips: · Use at least #10 AWG wire for the +BATT (+12 Vdc) and GND (ground) connections. If needed, use at least a #20 AWG wire for the REM (remote) connection. · Route all power wires through a grommet in the vehicle's firewall. If a factory grommet is unavailable, install one. · Connect a short GND wire from BassLink T to the nearest bare metal surface. For a good connection, scrape away paint from the metal surface and use a screw with a lock (star) washer. · Install a fuse holder with a 25 A fuse within 18" of the battery's positive (+) terminal (see Figure 6). · The REM connection requires +5 to +12 Vdc signal to turn on BassLink T. Most head units with preamp outputs provide this remote voltage signal. For speaker-level applications, a remote connection is preferred but not required, since BassLink T's Auto Turn-On feature will sense voltage on the speaker wires to automatically turn on BassLink T. IMPORTANT: To enable BassLink T's Auto Turn-On feature, set the AUTO TURN-ON switch to the AUTO position (see Figure 12 on page 7). Fuse 25 A FUSE 25A +BATT Figure 6. Power connections for BassLin
