User manual JBL BASSPRO II

[. . . ] · Check clearances on both sides of a planned mounting surface. Be sure that screws or wires will not puncture brake lines, fuel lines or wiring harnesses, and that wire routing will not interfere with the safe operation of the vehicle. · When making electrical connections, make sure they are secure and properly insulated. [. . . ] Use at least #20 AWG speaker wire for speaker-level input connections. Use at least #12 AWG wire for the Positive Battery (BATT +12) and Ground ( ) connections. If needed, use at least #20 AWG wire for the remote (REM) turn-on connection. Connect BassPro II's "BATT +12V" terminal directly to the battery's positive (+) terminal. Install a fuse holder, with a 20A fuse, within 18" of the battery's positive (+) terminal. Route all power wires through a grommet in the vehicle's firewall. Connect a short ground wire from BassPro II's ground terminal ( ) to the nearest bare metal surface. For a good connection, use sandpaper to clear paint from the metal surface and use a screw with a lock (star) washer. The remote (REM) connection requires a +5 to +12 Vdc signal for BassPro II to turn on when using the line-level connections. Most head units with preamp outputs provide this remote voltage signal. As an alternative, connect this terminal to a switched ignition circuit.
