Connecting to Power
When connecting the stereo to power, you should connect it
through the ignition or another manual switch.
If it is necessary to extend the power and ground wires, use
14 AWG (2.08 mm
2
) wire. For extensions longer than 1 m (3 ft.),
use 12 AWG (3.31 mm
2
) wire.

Speaker Zones
You can group speakers in one area into speaker zones. This
enables you to control the audio level of the zones individually.
For example, you could make the audio quieter in the cabin and
louder on deck.
You can set the balance, volume limit, subwoofer level, and
name for each zone.
