TURNING ON THE AMPLIFIER
The amplifier automatically turns on a few seconds after you turn your vehicle's ignition
switch to ACC or turn on your auto sound system (depending on how you have wired
the system). The POWER indicator on the top of the amplifier illuminates when the
amplifier is on.
I
mportant : 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: Your amplifier temporarily shuts down if it gets too hot, then restarts automatically
once it cools.
NOTE Raising the LPF frequency allows higher frequencies to reach the bass speakers
while blocking lower frequencies from midrange speakers. Lowering the LPF frequency
allows lower frequencies to reach the midrange speakers while blocking higher
frequencies from bass speakers.

Adjusting and Tuning
For the best performance, you must set GAIN (4V/0.2V) 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 (4V/0.2V) fully counterclockwise to 4V.
2. Turn the auto sound system's volume control to about one-third of its full range.
3. Adjust GAIN (4V/0.2V) 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 (4V/ 0.2V) 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.
