COMPLETING THE INSTALLATION

TESTING THE

CONNECTIONS

Before you continue, make sure you have securely made all connections. Then reconnect the cable to the vehi- cle’s negative (–) battery terminal.

Set LEVEL (MIN/MAX) on both ends of the amplifier to its mid position (see “Adjusting the Audio Level” on Page 18). Then turn on your vehicle’s ignition and autosound system to con- firm that the amplifier and autosound system operate properly. The amplifi- er turns on after a few seconds.

If you cannot quickly confirm whether the autosound system and amplifier are working properly, turn off your

vehicle’s ignition and disconnect the cable from your vehicle’s nega- tive (–) batter y terminal. Then re- check your connections.

After you test the autosound system and amplifier and verify that every- thing is properly connected and work- ing, follow the instructions in “Mounting the Amplifier.”

MOUNTING THE

AMPLIFIER

Once you verify that the amplifier is connected properly, follow these steps to mount it.

1.Disconnect the cable from the vehicle’s negative (–) battery ter- minal.

2.To make mounting more conve- nient, temporarily disconnect the amplifier’s connections (ground, primary power, remote power, your autosound system’s input, and speakers).

Note: If you have not already done so, be sure to mark each wire with the name of the terminal you will reconnect it to.

3.Using the mounting holes on the amplifier as a guide, mark the positions for the mounting holes.
