Adjusting the Subwoofer Filter

You can use the subwoofer filter setting to control the subwoofer cutoff frequency, which can enhance the blend of the sound produced by the speakers and the subwoofer. Audio signals above the selected frequency are not passed to the subwoofer. The setting applies to both subwoofer outputs.

NOTE: If a DSP profile has been applied using the Garmin® Audio app, this setting cannot be changed on the stereo.
  1. Select menu symbol > SETTINGS > ZONE > ZONE 1 > SUB FILTER.
  2. Select a frequency.
