Troubleshooting
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-
OVER FREQ
for your particular vehicle’s
acoustics. The amplifier passes through all
frequencies at or below that setting (45
−
400
Hz).
Note:
X-OVER FREQ
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.
