CONTROLS
4. GAIN: The gain control is used to match the output of your radio
to the output of your powered subwoofer. To properly set the
gain, first rotate it all the way counter-clockwise to MIN. Turn on
your radio, set your EQ settings to flat and slowly increase the
volume of your radio until you start to hear distortion. Then turn
the volume down to the point where the distortion goes away.
Next increase the gain on your powered subwoofer until you
begin to hear distortion. Finally, adjust the gain back down until
you find the point where the distortion goes away. Your radio
and powered subwoofer levels are now matched.
5. RCA INPUT (CH1): This is the input for the left RCA connector.
RCA INPUT (CH2): This is the input for the right RCA connector.
6. POWER: The power LED illuminates when the powered
subwoofer is activated.
7. POWER/HIGH LEVEL INPUT: This is the input for the wiring harness.
