TESTING THE CONNECTIONS

Before you permanently mount the amplifier, connect your vehicle battery’s neg- ative (-) cable, turn your vehicle’s ignition to ON or ACC, then test the connec- tions.

The amplifier is properly connected to the autosound system and speakers if you can verify that the amplifier and the autosound system turn on properly and the speakers’ sound is clear and unmuffled.

If you cannot quickly verify that all components operate properly, immediately turn off your vehicle’s ignition. Then disconnect your vehicle battery’s nega- tive (-) cable and recheck your connections.

Once you verify that all components operate properly, mark the connections to insure easy identification of each wire, then follow the instructions under “Mount- ing the Amplifier.”
