  4. How to setup AccuBass.

AccuBass is a feature that restores bass frequencies on a factory system that rolls off the bass as you turn up the volume. If you can hear that the bass does not increase as you continue to turn up the volume on the head unit then your factory system is most likely rolling off bass.

There are two AccuBASS® settings used during initial setup. The AccuBass Threshold and the AccuBass Level. The AccuBASS Threshold determines when the AccuBASS process turns on and the AccuBASS Level adjusts how much bass is restored.

For initial setup of AccuBASS:

  1. Turn the AccuBASS Threshold all the way to the left
  2. Set the AccuBASS Level knob at the 12 O’clock position
  3. Start playing music that you are familiar with and that has a lot of bass
  4. Slowly turn the volume up on the head unit until you start to hear the bass start to drop out (roll off)
  5. At this point, you will now start to slowly turn the AccuBASS Threshold to the right (clockwise) until you hear the bass being restored.
  6. At this point the Threshold is set and you can now adjust the AccuBASS Level to your liking. You can think of the AccuBASS Level setting as a bass boost feature as it is adjusting how much bass is restored.

If your vehicle does not reduce the bass output at higher volumes there is a way to defeat the AccuBASS feature or, if you prefer, to keep it turned on all the time.

To keep AccuBass ON all the time turn the Threshold knob all the way to the right, which will effectively keep the AccuBASS process always engaged. So no matter how loud or soft you are playing music, AccuBASS will always be adding bass boost.  You can still adjust your AccuBass Level to your liking.

To defeat (turn off) the AccuBass feature you would turn the Threshold all the way to the left which will prevent the AccuBass process from turning on at higher volumes. You would also turn the AccuBass Level all the way down (to the left).
