Notes
• When using a two-speaker installation, the Green, Green/Black, Violet, Violet/
Black wires, which are used for a four-speaker installation, are not used.
The ends of these wires must be covered with electrical tape to prevent them
from shorting to the unit or the vehicle chassis.
• When using a two-speaker installation, set the FADER control to the center
position.
