INSTALLATION WARNINGS AND TIPS

• Always wear protective eyewear when using tools.

• Disconnect the vehicle’s negative (–) battery terminal before starting
the installation.

• 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.

• I f you must replace the GT-BassPro12’s fuse, be sure to use the same

type of fuse and current rating as that of the original.

MOUNTING THE SUBWOOFER

Choose a location for the subwoofer that doesn’t interfere with cargo,
a fold-down rear seat or the trunk lid. The best location is usually a
corner of the trunk or cargo area, as shown in the illustrations. Choose a
mounting location in the front of the vehicle for the remote level control.
