crossover mode selector
when used with normal, full range systems, set this switch to “FULL”. If
you wish the internal crossover to power a driver of specific frequency
range , use the “LOWPASS” or “HIGHPASS” settings.

use this control to match the outputs of you head unit to the amplifier.
Starting with your head unit set at about the 2 o’clock position, increase
the amp level control until distortion begins to occur, and reduce slightly
from this point.
