APSUB-CH21
PLEASE NOTE: These settings can be adjusted with the module installed in the vehicle or on the bench. However, it is
recommended to make the adjustments with the module installed, and the factory radio on so that the changes can be
heard.
Minimum Volume Level -
This allows you to set the minimum volume level of the factory radio (factory radio volume level 1).
EQ Enabled -
This allows you to enable / disable the bass band factory EQ.
Bass Freq / Q Factor -
This allows you to set the center frequency that will be adjusted when setting the bass band on the
factory EQ, as well as the Q Factor for each frequency. The Q Factor determines how many of the adjacent frequencies will
be affected when adjusting the selected frequency. The lower the Q Factor, the more frequencies will be affected. Note: This
setting only affects the output of the APSUB and does not change the way that the factory EQ adjusts the factory speakers.
