TESTING THE

CONNECTIONS

Before you continue, make sure you have securely made all connections. Then recon- nect the cable to the vehicle’s negative () battery terminal.

Seton the left and right sides of the amplifier to its mid position (see “Adjusting the Audio Level” on Page 18). Then turn on your vehicle’s ignition and auto sound system to confirm that the amplifier

and auto sound system operate properly. The amplifier turns on after a few seconds.

If you cannot quickly confirm whether the auto sound system and amplifier are working properly, turn off your vehicle’s ignition and disconnect the cable from your vehi-

cle’s negative (–) battery terminal. Then

recheck your connections.

After you test the auto sound system and amplifier and verify that everything is proper- ly connected and working, follow the instruc- tions in “Mounting the Amplifier.”

MOUNTING THE AMPLIFIER

Sheet Metal Screw

Lock Washer

Flat Washer

9/64-Inch Mounting Hole

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

1.Disconnect the cable from the vehicle’s negative (–) battery terminal.

2.To make mounting more convenient, temporarily disconnect the amplifier’s connections (ground, primary power, remote power, your auto sound 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 ampli- fier as a guide, mark the positions for the mounting holes.

4.Drill 9/64-inch (3.57 mm) holes at the marked locations, being careful not to damage anything behind the mounting surface.
