If the user wishes to test the polarity of the Cub with a battery, the plus (+) ter-
minal of the battery is connected to the RED (+) input terminal of the Cub and
the negative (-) terminal of the battery is connected to the BLACK (-) terminal
of the Cub. The results of this test will show the Cub woofers to move outward.
This is the correct driver movement in response to a D.C. signal.
