WIRING DIAGRAM
  When using the high-level input connections, BassProII will automatically turn on when you turn on your radio.  In this case, the remote (REM) connection is not needed. 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. If a factory grommet is not available, install one.  Connect a short ground wire from
  Bass Pro II’s ground terminal GND 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 Bass Pro 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.
