Notes
Connects the stereo to a typical
AM/FM antenna using an RF
coaxial connector.
If you are installing the stereo on a
boat with a metal hull, you must use
a ground-dependent antenna, and if
you are installing the stereo on a
boat with a non-metal hull, you must
use a ground-independent antenna.
See the installation instructions
provided with your antenna for more
information.
Provides a red and white RCA
stereo line input for audio sources,
such as a CD or MP3 player.
Provides a full-range output to an
external amplifier, and is associated
with the volume and tone for zone 1.
Connects to the positive terminal of
a 12 Vdc power source capable of
supplying 15 A.
Connects to the negative terminal of
a 12 Vdc power source. This wire
should be connected before
connecting the yellow wire. All
accessories connected to the stereo
must share a common ground
location.
Connects to an optional external
amplifier to turn it on when the
stereo turns on.
Connects to the boat's illumination
wire to dim the stereo screen when
the lights are on.
The gauge of the illumination wire
must be suitable for the fuse
supplying the circuit it is connected
to.

2
14 AWG (2.08 mm ) wire. For extensions longer than 1 m (3 ft.),
2
use 12 AWG (3.31 mm ) wire.
1 Route the power wire
switch , and route the black ground wire
2
If necessary, route a wire
battery .
3
Route the wiring-harness plug to the stereo.

of the bare wire connections have been made.
4 Connect the black wire to the negative (-) battery terminal.
5
Connect the power wire to the ignition or another manual
switch, and connect the switch to the positive (+) battery
terminal if necessary.
