Operation

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 on the
side of the amplifier lights when the amplifier
is on.

Important:  Your amplifier requires 60 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.

Note: Your amplifier temporarily shuts down
if it gets too hot, then restarts automatically
once it cools.

ADJUSTING THE AUDIO 
LEVEL

For the best performance, you must set 

LEV-

EL (MIN/MAX) 

on the left and right sides of the

amplifier to adjust the level of the audio sig-
nals that enter the amplifier. 

1. Use a screwdriver to turn 

LEVEL (MIN/

MAX)

 on the left and right sides of the

amplifier fully counterclockwise to 

MIN

.

2. Turn the auto sound system’s volume

control to about one-third of its full
range.

3. On the left and right sides of the ampli-

fier, adjust 

LEVEL (MIN/MAX)

 to a com-

fortable 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 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. On the left and right sides of the ampli-

fier, 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.
