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

If necessary, route a wire
between the switch and the battery .

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.
