Car audio system’s head unit has front
or rear stereo line level outputs:
Use a stereo RCA audio cable (not supplied) to connect the GTBassPro12’s line-level input connectors to the head unit’s front or rear left and right line-level outputs.

Car audio system’s head unit has a
line-level subwoofer output:
If the head unit has a line-level subwoofer output, you can connect it to either of the GT-BassPro12’s line-level input connectors.

Car audio system’s head unit does not
have line-level outputs:
Connect the GT-BassPro12’s high-level inputs to either the front or the rear speaker outputs of your car audio system’s head unit (splice crimps not included). Make sure to connect the car audio system’s “+”
speaker wires to the “+”wires on the GT-BassPro12’s high-level input wiring harness (the gray and white leads without stripes); connect the car audio system’s “–” speaker wires to the “–” wires on the GT-BassPro12’s high-level input wiring harness (the leads with black stripes). Use least #20 AWG (0.8128mm) speaker wire for speaker-level input connections.

Connecting the power and ground
Use at least #12 AWG (2.052mm) wire for the positive battery (“+12V”) and ground (“GND”) connections. Connect the GT-BassPro12’s “+12V” terminal directly to the battery’s “+” (positive) terminal. Install a fuse holder with a 20A fuse within 18” (46cm) of the battery’s “+” terminal.

Route all power wires through grommets in the vehicle’s firewall.
If factory grommets are not available, install grommets yourself. Connect a
short ground wire from the GT-BassPro12’s ground terminal to the
nearest bare metal surface on the vehicle. For a good connection, use sandpaper to clear the paint from the metal surface and use a screw with a lock (star) washer.

Remote turn-on connection
When using the line-level input connections, the GT-BassPro12 requires a +5V to +12V DC signal at the Remote (REM) connector to turn on. Most head units with preamp outputs provide a remote turn-on wire that supplies this remote voltage signal. (As an alternative, you can connect the REM terminal to a switched ignition circuit.) Use at least #20 AWG (0.8128mm) wire for the remote turn-on connection.

Note: The remote turn-on connection is not
needed when using the high-level input connections.
