TURNING ON THE

AMPLIFIER

The amplifier automatically turns on a few seconds after you turn your vehicle’s ignition switch to ACC or ON or turn on your auto sound system, depending on how you wired the system. The POWER indicator lights when the amplifier is on.

ADJUSTING THE AUDIO LEVEL

For the best performance, you must set

EL (MIN/MAX) on the amplifier to adjust the level of the audio signals that enter the am- plifier.

1.Use a screwdriver to turn LEVEL (MIN/ MAX) fully counterclockwise to MIN.

Important: Your amplifier requires 17 amps or more of power from your vehicle’s battery during operation. To protect your battery from discharging, do not operate the amplifi- er unless your vehicle is running.

2.Turn up the auto sound system’s volume control to about one-third of its full range.
