Speaker Zones - Fusion Apollo MS-WB670 Installation Instructions Manual

1
Route the yellow power
wires to the battery, and route the wiring-harness plug to
the stereo.
Do not connect the wiring harness to the stereo until all of the
bare wire connections have been made.
2
Connect the black wire to the negative (-) battery terminal.
3
If you are routing the red wire through the ignition or another
manual switch , connect the red ignition wire to the ignition
or switch.
4
Connect the red wire to the yellow wire, install a 15 A fuse
as close to the battery as possible, and connect both wires to
the positive (+) battery terminal.
NOTE: If you are running the red wire through a fused switch,
it is not necessary to connect the red wire to the yellow wire
or to add an another fuse to the red wire.

Speaker Zones

You can group speakers in one area into a speaker zone. 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.
Up to two pairs of speakers can be connected per channel of
each zone, in parallel. One zone can support no more than four
speakers using the on-board amplifier.
Zones 1 and 2 are powered by the on-board amplifier. Zone 3 is
available as a line-level output only. To use the RCA line output
and the RCA subwoofer output for zone 3, you must connect an
external amplifier.
You can set the balance, volume limit, tone, subwoofer level,
subwoofer frequency, and name for each zone, and configure
other zone-specific settings.

Speaker System Wiring Using a Line Out
This diagram illustrates a system installation with an external
amplifier and subwoofer connected to zone 2 on the stereo
using a line out. You can connect an amplifier and subwoofer to
any or all of the available zones on the stereo.
NOTE: You can connect speakers to the speaker wires for the
internal stereo amplifier while using the line out on zones 1 and
2, although adjusting the volume affects both the speakers
connected to the internal amplifier and the line out. This may
result in uneven volume levels.
