Connecting to Power
When connecting the stereo to power, you must connect both
power wires. The yellow power wire must connect to the battery
to provide sufficient power to the stereo. The red ignition should
be connected through the ignition or another manual switch to
enable on/off control of the stereo. This installation method
provides the best performance because the yellow wire retains a
constant trickle-power draw that optimizes the startup time for
the stereo.
NOTE: If you will be storing the vessel for an extended period of
time, you should consider connecting the yellow wire through a
breaker or similar switch, so you can disconnect the trickle-
power draw from the yellow wire and avoid draining the battery
during storage.
If you do not have the option of, or prefer not to use the ignition
to turn the stereo on and off, you can connect the red wire and
the yellow wire to the same switch on an electrical panel. This
installation method results in a slightly longer startup time for the
stereo, but it will not draw power from the battery when the
stereo is turned off using the switch.
You must connect the power wires to the battery through a 15 A
fuse or a 15 A circuit breaker.
If it is necessary to extend the yellow power and black ground
wires, use 14 AWG (2.08 mm
1 m (3 ft.), use 12 AWG (3.31 mm²) wire.
If it is necessary to extend the red ignition wire, use 22 AWG
2
(0.33 mm ) wire.
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 additional fuse to the red wire.

Notes
Provides an RCA stereo line input for
audio sources, such as a CD or MP3
player.
Provides output to an external
amplifier, and is associated with the
volume control for zone 3.
Each subwoofer cable provides a
single mono output to a powered
subwoofer or subwoofer amplifier.

, red ignition , and black ground
If you connect both the red and yellow wires through a 15 A
circuit breaker, it is not necessary to add an additional fuse.
5 Connect the wiring harness to the stereo.
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.

Zone 2 speakers
Amplifier-on signal wire
You must connect this wire to each amplifier connected to a zone
line out.
A connected amplifier must use the same ground (-) as the stereo
for this signal wire to function correctly.
