Tuning on the Amplifier
Adjusting The Audio Level
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 on the top of the amplifier lights when the amplifier is on.
Important : Your amplifier requires 30 amps or more of power from your vehicle's
battery during operation. To protect your battery from discharging,
do not operate the amplifier unless your vehicle is running.

NOTE:
Raising the Bass frequency allows higher frequencies to reach the bass speakers
while blocking lower frequencies from midrange speakers. Lowering the Bass
frequencies allows lower frequencies to reach the midrange speakers while
blocking higher frequencies from bass speakers.
For the best performance, you must set GAIN (MIN / MAX) on the side of the
amplifier to adjust the level of the audio signals that enter the amplifier.
1. Use a screwdriver to turn GAIN (MIN / MAX) fully counterclockwise to MIN.
2. Turn the auto sound system's volume control to about one-third of its full range.
3. Adjust GAIN (MIN / MAX) to a comfortable listening level.
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
distortion began.
Caution : Never turn up the auto sound system's volume control more than needed
to adjust the audio level, more than two thirds of its maximum volume.
5. Adjust GAIN (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.
