4.Turn up the auto sound system’s volume control until the sound begins to distort. Then immediately 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 vol- ume.

5.Adjust LEVEL (MIN/MAX) until the sound is at the maximum level you want the amplifier to produce.

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

ADJUSTING FREQUENCY CROSSOVER

If you installed a subwoofer using the steps in “Connecting a Subwoofer” on Page 13, set X-OVER FREQ ON/OFF to ON, then adjust X- for your particular vehicle’s acoustics. The amplifier passes through all

frequencies at or below that setting (45−400 Hz).

Note:selects the limit at which the amplifier will pass frequencies (from 45− 400 Hz). You should not use it to adjust the sound you hear through your main speakers.
