Mounting Considerations
• You must mount the stereo on a flat surface that provides open airflow around the rear of the stereo for heat
ventilation.
• If you are installing the stereo in a location that may be exposed to water, you must mount it within 45
degrees of the horizontal plane.
• If you are installing the stereo in a location that may be exposed to water, add a drip loop to the cable to
allow water to drip off of the cable and avoid damage to the stereo.
• If you need to mount the stereo outside a boat, you must mount it in a location far above the waterline, where
it is not submerged, and where it cannot be damaged by docks, pilings, or other pieces of equipment.
• To avoid interference with a magnetic compass, you must install the stereo at least 10 cm (3.9 in.) away
from a compass.

Mounting the Stereo
NOTICE
Do not use the stereo as a template when drilling the mounting holes because this may damage the display and
void the warranty. You must only use the included template to correctly drill the mounting holes.
Be careful when cutting the hole to mount the 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.
Be careful when installing the stereo in an aluminum boat or a boat with a conductive hull, if you require the
electrical system to be isolated from the boat hull.
Do not apply grease or lubricant to the screws when fastening the stereo to the mounting surface. Grease or
other lubricants can cause damage to the stereo housing.
Before you can mount the stereo in a new location on the mounting surface, you must select a location in
accordance with the mounting considerations.
1Adhere the template to the mounting surface.
2Drill a hole inside the corner of the dashed line on the template.
3Cut the mounting surface along the inside of the dashed line on the template.
4Ensure the mounting holes on the stereo line up with the pilot holes on the template.
5Using an appropriately sized drill bit for the mounting surface and screw type, drill the pilot holes.
6Remove the template from the mounting surface.
7Complete an action:
• If you are installing the stereo in a dry location, place the included mounting gasket on the back of the
stereo.
• If you are installing the stereo in a location that is exposed to water, apply silicone-based marine sealant
on the mounting surface around the cutout.
NOTICE
Do not install the included mounting gasket if you applied sealant to the mounting surface. Using sealant
and the mounting gasket may reduce water resistance.
8If you will not have access to the back of the stereo after installation, make the necessary wiring
connections.
9Secure the stereo to the mounting surface using the included screws .
You should hand-tighten the screws when securing the stereo to the mounting surface to avoid over
tightening them.
10 Snap the screw covers in place .
Connection Considerations
You must connect the stereo to power, to speakers, and to media input sources. You should carefully plan the
layout of the stereo, speakers, input sources, and optional Fusion PartyBus™ devices and Fusion PartyBus
network before making any connections.

Apollo SRX400 Installation Instructions 5
Power Connection
When connecting the stereo to power, you must connect the yellow, red, and black wires to the power source.
The yellow and red wires have different functions, and the method you use to connect them to power depends
on how you plan to use the stereo on your vessel.
Yellow wire
• This wire provides power to the stereo.
• This wire should be connected through a 15 A circuit breaker, if one is available on the vessel.
NOTICE
If a 15 A circuit breaker is not available on the vessel, you must connect this wire to power through a 15 A
fuse (not included).
• This wire provides power to the stereo at all times, and it will drain the battery even when the stereo is not
in use. You should install a manual switch on this wire if a 15 A circuit breaker is not available on the
vessel, or if you cannot toggle the breaker to remove power to the stereo when storing the vessel.
• If it is necessary to extend this wire, use 14 AWG (2.08 mm2) wire. For extensions longer than 1 m (3 ft.),
use 12 AWG (3.31 mm²) wire.
Red wire
• This wire can be connected to the same power source as the yellow wire through the ignition or through a
manual switch. This enables you to turn the stereo on and off automatically when you turn the vessel on
and off, or when you activate the switch.
• Using this wire to turn the stereo on and off behaves in the same way as using the power button on the
stereo to turn it on and off. It is not necessary to connect this wire to a switch if you plan to toggle the
power using the power button on the stereo or using a connected chartplotter or remote control. This wire
must be connected to turn the stereo on.
• When you turn off the stereo using this switch or the power button, it enters a standby mode that allows
the stereo to start up again faster than if you switch the power off using the yellow wire. When it is in
standby mode, the stereo uses up to 200 mA, and you must turn off power to the stereo on the yellow wire
thorough the circuit breaker or manual switch when you are not using the vessel to avoid draining the
battery.
•NOTICE
You must connect this wire to power through a 1 A fuse (not included), whether or not you connect it to
the ignition or manual switch.
• If it is necessary to extend this wire, use 22 AWG (0.33 mm2) wire.
Black wire
• This is the ground wire, and you must connect it to the negative terminal of the power source or to a
common ground.
• If it is necessary to extend this wire, use 14 AWG (2.08 mm2) wire. For extensions longer than 1 m (3 ft.),
use 12 AWG (3.31 mm²) wire.

Connecting to Power Without Using an Ignition Switch
This method of connection is used most often on larger vessels and on vessels with multiple networked
stereos and other marine devices. For these installations, a faster startup time is typically less critical, and it is
more effective to use the breaker or a dedicated switch on the electrical panel to turn off the stereo and ensure
that no unexpected power drain occurs.
1Consult this diagram to plan the wire connections.
Item Description Notes
Yellow wire You should connect this wire to the red wire before you connect both
wires to the manual switch or circuit breaker.
Red wire You should connect this wire to the yellow wire so that it does not act as a
physical standby switch.
1 A fuse (not included) You must install this fuse on the red wire before you connect the red wire
to the yellow wire.
Manual switch
(optional)
This switch is needed only if a circuit breaker is not available or if it
provides a more convenient method of cutting power to the stereo.
Black wire Ground (-)
15 A fuse (not included)
This fuse is required if you are not able to connect to power through a
15 A circuit breaker .
15 A circuit breaker If a circuit breaker is not available, you must connect a 15 A fuse on
the yellow wire
2Route all wires to the stereo wiring harness, the circuit breaker or switch, and the power source as
necessary.
Do not connect the wiring harness to the stereo until after you have made all of the bare wire connections.
3Install all of the necessary fuses on the red and yellow wires.
4Connect the wiring harness to the stereo.
When the circuit breaker or manual switch is closed, the stereo is always on. You can use the power button on
the stereo or a connected chartplotter or remote control to place the stereo in a low-power standby mode if
needed.
NOTE: When you are not using the vessel, you should remove power to the stereo using the circuit breaker or
manual switch to avoid draining the battery.
Apollo SRX400 Installation Instructions 7
Connecting to Power Through an Ignition Switch
This method of connection is used most often on ski boats, wake boats, and similar sport or recreational
vessels where power to the engines is toggled often. For these installations, a quick standby and faster startup
time is desired so that music can be stopped and begin playing again as quickly as possible after restarting the
engines. When in standby mode, the stereo uses up to 200 mA, and you should connect the power wires
through a circuit breaker or manual switch to avoid draining the battery when you are not using the boat.
1Consult this diagram to plan the wire connections.
Item Description Notes
Yellow wire You must connect this wire to the same power source as the ignition or
ACC switch.
Red wire You must connect this wire to the ignition or ACC switch before you
connect it to the same power source as the yellow wire.
1 A fuse (not included) You must install this fuse on the red wire before you connect the red wire to
the ignition or ACC switch.
Ignition or ACC switch
Connecting the red wire to this switch allows the stereo to enter a low-
power standby mode when you turn off the engines, so it can start up faster
when you turn on the engines again.
Black wire Ground (-)
15 A fuse (not
included)
This fuse is required if you are not able to connect to power through a 15 A
circuit breaker .
15 A circuit breaker or
manual switch
If a circuit breaker is not available, you must connect a 15 A fuse on the
yellow wire. You should also connect the yellow wire to power using a
manual switch, so you can remove power to the stereo when you are not
using the boat.
2Route all wires to the stereo wiring harness, the ignition or ACC switch, the circuit breaker, and the power
source as necessary.
Do not connect the wiring harness to the stereo until after you have made all of the bare wire connections.
3Install all of the necessary fuses on the red and yellow wires.
4Connect the wiring harness to the stereo.
When you turn on the ignition switch, the stereo turns on along with other accessory electronics. When you turn
off the ignition switch, the stereo enters a low-power standby mode.
NOTE: When you are not using the vessel for an extended period of time, you should remove power to the
stereo using the circuit breaker or other manual switch on the yellow wire to avoid draining the battery.

Powered amplifier
Line out and subwoofer out
The subwoofer cable provides a single mono output to a powered subwoofer or subwoofer amplifier.
You may need to use an RCA splitter to connect this to an amplifier.
Amplifier-on signal wire
A connected amplifier must use the same ground (-) as the stereo for this signal wire to function
correctly.
Subwoofer
NOTE: You can connect speakers to the speaker wires for the internal stereo amplifier while using the line out,
although adjusting the volume affects both the speakers connected to the internal amplifier and the line out.
This may result in uneven volume levels.
Apollo SRX400 Installation Instructions 9
Fusion PartyBus Networking
The Fusion PartyBus networking feature allows you to connect multiple compatible stereos together on a
network, using a combination of wired or wireless connections.
You can group a compatible stereo, such as the Apollo RA770 stereo, with other compatible stereos connected
to the network. Grouped stereos can share available sources and control media playback on all of the stereos
in the group, which allows for a synchronized audio experience across the vessel. You can quickly create, edit,
and break up groups as needed from any compatible stereo or remote control on the network.
NOTE: A zone stereo, such as the SRX400, can create or join a group to control and play sources from other
stereos, but it cannot share its sources with the group.
For additional considerations when sharing sources, see the owner's manual.
You can use compatible stereos and remote controls, whether they are grouped or not, to adjust the volume of
the available speaker zones for any stereo on the network.
You can connect up to eight Fusion PartyBus stereos on a network wirelessly.
Wired Networking Considerations
When you are planning your network installation, observe the following considerations for all wired
connections.
• You must connect devices using standard Cat5e or Cat6 network cables with RJ45 connectors.
• You can use one network cable to directly connect two compatible devices.
• You must use wired network switches and wired or wireless network routers when you connect more than
two compatible devices to a network.
• If you install a router on the network, it should be configured to be a DHCP server by default. See your router
instructions for more information.
• If you do not install a router, and there are no other DHCP servers on the network, you should configure one
Fusion PartyBus stereo to be a DHCP server (Setting the Fusion PartyBus Device as the DHCP Server,
page 14).
Wired Network Example for Direct Connections
No network setting changes are needed when connecting two devices together directly, but for the best results,
you should configure one device to be a DHCP server (Setting the Fusion PartyBus Device as the DHCP Server,
page 14).
