Mounting Considerations

• The stereo must be mounted in a location where there is
enough clearance for the open door of the stereo as
indicated on the template.

• The stereo must be mounted in a location that allows open
airflow around the rear of the stereo for heat ventilation.

• The stereo must be mounted within 45° of the horizontal
plane.

•

The cable should have a drip loop to allow water to drip down
off the cable and avoid damaging the stereo.

• If you want to mount the stereo outside the boat, it must be
mounted in a location well above the waterline, where it is not
submerged.

• If you want to mount the stereo outside the boat, it should be
mounted in a location where it will not be damaged by a
docks, pilings, or other pieces of equipment.

• To avoid interference with a magnetic compass, the stereo
should be installed at least 15 cm (5.9 in.) away from a
compass.

Mounting the Stereo

NOTICE

Be careful when cutting the hole to flush mount stereo. There is
only a small amount of clearance between the case and the
mounting holes, and cutting the hole too large could
compromise the stability of the stereo after it is mounted.

Before mounting the stereo, you must choose a location
following the guidelines above.

1

Trim the template and make sure it fits in the selected
location.

2

Secure the template to the selected location.

3

Using a drill bit appropriate for the mounting surface, drill the
hole inside the corner of the dashed line on the template to
prepare the mounting surface for cutting.

4

Using a jigsaw or rotary tool, cut the mounting surface along
the inside of the dashed line indicated on the template.

5

If necessary, remove the sun cover from the stereo.

6

Place the stereo in the cutout to test the fit.

7

If necessary, use a file and sandpaper to refine the size of
the cutout.

8

After the stereo fits correctly in the cutout, ensure the
mounting holes on the stereo line up with the pilot holes on
the template.

9

If the mounting holes on the stereo do not line up, mark the
new pilot-hole locations.

10

Using an appropriately sized drill bit for the mounting surface
and screw type, drill the pilot holes.

11

Remove the template from the mounting surface.

12

Connect the wiring harnesses and wires, while observing
polarity.

13

Place the mounting gasket on the back of the stereo À.

14

If necessary, place the nut plates Á behind the dashboard.

15

Place the stereo in the cutout.

16

Secure the stereo to the mounting surface using the included
screws Â.

17

If necessary, secure the back of the stereo with a back strap
or brace (not included).

Connection Considerations

The stereo must be connected to power, to speakers, and to
media input sources to function correctly. You should carefully
plan the layout of the stereo, the speakers, and your input
sources before making any connections.

Notes

Power (+) Yellow This should be connected to a constant

12 Vdc source capable of supplying
15 A. All 12 V wiring must be fused at
the power source end of your cable
using a 15 A fuse.

Ground (-) Black This should be connected battery

negative before connecting the yellow
wire. All accessories connected to the
stereo must share a common ground
location.

Ignition Red This should be connected to a

separately switched 12 Vdc connection,
such as an ignition bus, to turn the
stereo on and off. If you are not using a
switched 12 Vdc connection, you must
connect this to the same source as the
yellow (power) wire.

Amplifier on Blue This is connected only when using an

optional external amplifier.

Telephone Mute Brown When connected to ground and a call is

received on a hands-free mobile phone,
this mutes the audio or switches the
input to AUX IN 2. This is configurable
in the settings menu.

Dim Orange This can be connected to the boat's

illumination wire to dim the stereo
screen when the lights are on.

This must be connected to a wire
gauge suitable for the fuse supplying
the circuit it is connected to.

Connecting to Power

When connecting the stereo to power, you must connect both
power wires. The yellow power wire should be connected
directly to the battery, or connected using a 15 A isolator switch.
This provides power to the stereo and a constant trickle-power
standby feed. The red signal wire should be connected to the
same battery through the ignition or another manual switch to
turn the stereo on and off.

If you are not routing the red wire to the ignition or another
manual switch, you can connect the yellow to the red, and
connect them to the positive (+) battery terminal. You should put
a fuse on the red wire.

If it is necessary to extend the yellow power and black ground
wires, use 14 AWG (2.08 mm2) wire. For extensions longer than
1 m (3 ft.), use 12 AWG (3.31 mm²) wire.

If it is necessary to extend the red signal wire, use 22 AWG
(0.33 mm2) wire.

1

Route the yellow power À and black ground Á 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.
