OPERATION

TURNING ON THE

AMPLIFIER

The amplifier automatically turns on a few seconds after you turn your vehi- cle’s ignition switch to ACC or ON, or turn on your autosound system, de- pending on how you wired the system. The POWER indicator on the side of the amplifier lights when the amplifier is on.

Important: Your amplifier requires 25 amps or more of power from your vehi- cle’s battery during operation. To pro- tect your battery from discharging, do not operate the amplifier unless your vehicle is running.

Note: Your amplifier temporarily shuts down if it gets too hot, then restarts au- tomatically once it cools.

ADJUSTING THE AUDIO LEVEL

For the best performance, you must set LEVEL (MIN/MAX) on the end of the amplifier to adjust the level of the audio signals that enter the amplifier.

1.Use a screwdriver to turn both

LEVEL (MIN/MAX) controls fully counterclockwise to MIN.

2.Turn the autosound system’s vol- ume control to about one-third of its full range.

3.Adjust both LEVEL (MIN/MAX) con- trols to a comfortable listening level.

4.Turn up the autosound system’s volume control until the sound begins to distort. Then immedi- ately turn the volume down to a point just before where the distor- tion began.

Caution: Never turn up the auto- sound system’s volume control more than needed to adjust the audio level, or more than two- thirds of its maximum volume.

5.Adjust both LEVEL (MIN/MAX) con- trols until the sound is at the maxi- mum level you want the amplifier to produce.

6.Adjust the autosound system’s volume control to a comfortable listening level.
