Bypassing the filters
you neglect to place jumpers on either header, no signal will pass on that channel.

Subwoofers tend to sound best when used with suitable filtering, which prevents the
amplifier and speaker from wasting power trying to reproduce frequencies that are too
low. For best performance it is recommended that you bypass the high-pass filter only
if there is suitable filtering elsewhere in the audio signal path.
