Installation Guide

2
· Please read this Installation Guide and the User Guide before
installation and use. If you are unsure about installing this
product, please contact a professional audio installer.
· The Marine Gauge Radio is designed to be installed into a round
opening (refer to Mount Your Marine Radio for details), in boats,
golf carts, cars, and o-road vehicles. Mounting and wiring
may vary for dierent types of vehicles and are called out in this
installation guide.
· When you plan your Radio installation, please ensure that the
mounting surface is flat for best front panel sealing, check for
potential obstacles behind the mounting surface, and confirm that
the mounting surface has adequate clearance around the back of
the Radio for open airflow and for heat ventilation.
· Mount this product securely to prevent damage or injury in
severe conditions.
· BEFORE installation, disconnect any and all negative leads from
the battery’s negative (-) terminal to prevent damage to the unit,
fire, and/or possible injury.
· The Radio requires +12V DC voltage for the power input. If your
vehicle battery power is not 12V (e.g., 24V, 36V, or 48V), you will
need a DC-DC voltage converter with 12V output (e.g. a 48V-to-
12V converter). Connecting the Radio directly to higher voltages
will cause damage to the Radio and VOID THE PRODUCT
WARRANTY.
· The Radio power input has an in-line 35 Amp fuse. Do NOT replace
the fuse with one of a dierent value and never bypass the fuse.
· The Radio has a Remote Turn-On Input feature; this is to ensure
that the Radio is completely powered o (no battery consumption)
when your vehicle is not in use. When the input has a signal
between 12V and 56V, the Radio will turn on. When there is no input
voltage, the Radio will turn o. In general, this Remote Turn-On
signal comes from the vehicle ignition switch.

· You will need to connect the (Purple) Remote Turn-On Wire to
the vehicle ignition switch with the supplied (Purple) Remote
Turn-On Extension Cable. If you are not able to connect it to
your vehicle ignition switch, connect this input to a rocker switch
(not included), then connect the rocker switch to a 12V-to-56V
power supply on your vehicle or to a switch accessory panel.
· Alternatively, you can connect the Remote Turn-On Wire,
together with the (Red) Power Wire, directly to the positive
terminal of your vehicle’s battery. When the Radio is o, the
battery consumption is minimal for vehicles whose batteries are
charged multiple times a week.
· The Radio has 3 Power States:
· Powered – When the Radio has 12V power and your vehicle’s
ignition switch (or a rocker switch) is turned on, your Radio
is Powered. When it’s Powered, the Radio may be turned on
(Powered On) automatically or on Standby:
· Turn On (Power On) – When the Radio is in Turn On state, all
functions are accessible.
· Standby – When the Radio is on Standby, it goes into a low-
power consumption (sleep) mode. It turns o the Radio’s LED
Screen and button backlights, and all the functions except the
RF Remote Receiver, so that you can still use the Remote to
turn the Radio on.
· Powered O – When the vehicle’s ignition switch is turned
o, your Radio is Powered O. You will not be able to turn on
your Radio by pressing the Power Button on your Radio or the
included RF Remote Control.
Notes:
· When the Radio is in the Turn On State, you can press the Power
Button on the Radio or the RF Remote Control to put the Radio
Important

Important
into Standby State. If you press the Power Button again, it will
turn on the Radio.
· The Radio saves its Turn On (Power On) and Standby last
state into memory. When you turn on your vehicle’s ignition
switch, the Radio will go back to the same Power State that it
was in before it was Powered O. For example, if your Radio
is on and playing music, and you turn o your vehicle ignition
switch, then the next time you turn on your vehicle, your Radio
will turn on automatically.
· The first time you turn on your vehicle ignition switch after
installing your Radio, your Radio may turn on automatically, or
enter Standby, depending on the Radio’s Power State when it
was Powered O during the factory QA testing processes. If
your Radio is not on, press the Power Button to turn it on.
· The Radio has an integrated LED lighting controller with
four (4 Zones) LED lighting outputs. Each Zone can support
multiple types of SoundExtreme LEDCast-enabled products.
But it is NOT compatible with other manufactures’ LED
strips or LED whips. Do NOT make modifications to the
LED connectors or try to connect the LED outputs to other
manufacturers’ LED products. It may cause permanent
damage to the Radio and VOID THE PRODUCT WARRANTY.

Installation and Wiring
Safety and Wiring Considerations
· For easier assembly, it is recommended you run all wires prior to
mounting your unit in place.
· Pre-plan your system layout and best wiring routes to save
installation time. Carefully route all system wiring away moving
parts and sharp edges; secure with cable ties or wire clamps and
use rubber or plastic grommets where appropriate to protect from
sharp edges.
· To avoid short-circuiting, cover any disconnected leads with
electrical tape. It is important to insulate any unused wires, which, if
left uncovered, may cause a short circuit.
· Do NOT connect the Power Cable to your Vehicle’s battery until all
the installations and wirings are completed.
· When using the Extension Cable and/or connecting two wires
(e.g., using supplied BUTT Connectors), make sure to seal
the connection either by using electrical tape or heat shrink
tubing. Failing to do this may result in long-term corrosion on the
connection and cause a premature malfunction.
· Use high-quality, speaker cables and connectors to minimize
signal or power loss. 16 AWG speaker cable is recommended for
the Speaker Outputs.
· Route all of the audio cable and RCA cables close together and
away from any high current wires
Wiring Harness
Four sets of wiring harnesses are included in the package for you to
connect dierent signal inputs and outputs, depending on the audio
and LED lighting control connections in your system.

11
Installation and Wiring
Power Input and Remote Turn-On
1. Power In – An 8-foot 12 AWG SAE Power Cable is included for you
to connect the Radio to your vehicle’s 12V battery.
When you determine the power requirement from your battery,
you need to check both the power consumptions on the audio and
the LED lighting controls.
· If you only have 4 non-amplified speakers connected to the
2 Audio Zones, and no LEDCast Products connected to
the Radio, your 12V power source needs to be capable of
supplying 15A.
· If you have 4 non-amplified speakers connected to the 2 Audio
Zones, and 4 LEDCast Products connected to the 4 LED
Zones, you 12V power source needs to be capable of supplying
30A to support the maximum configuration of the connected
LEDCast Products. Depending on the type of LEDCast Product
you have, it may require lower current capacity on the battery
power source. Check your LEDCast Product’s specifications, or
contact SoundExtreme customer service for details.
Note: If you are connecting the LED controller to LED’s for
SoundExtreme wired speakers, the incremental power draw by
the LEDs is very small.
2. Remote Turn-On – An 8-foot Remote Turn-On Extension Cable
(Purple) is included for you to connect to your vehicle’s ignition
switch, rocker switch, or switched power panel.

J3 Cable Harnesses. Leave the Power Cable and Remote Turn-On
wire unconnected on both ends.
Proceed to the following wiring procedures.
Connect Wires to the 3 Cable Harnesses
1. Run all the wires from your Radio’s mounting location to the
previously mentioned power or external device’s locations. Mark
both ends of the wire / cable, so that you know which signal the
wire / cable is for when looking at either end.
2. Connect audio inputs and outputs:
· If you connect the Speaker Audio Output to non-amplified
speakers, connect the audio extension wire to the
corresponding wire on the J1 Cable Harness.
· If you connect the pre-amplified audio output to amplified
speakers or an audio power amplifier, connect the RCA
extension cables to the corresponding RCA jacks on the J2
Cable Harness.
When you connect the pre-amplified audio output to an audio
power amplifier, you will also need to connect the Amp-On
wire on the J1 Cable Harness to the corresponding input on
the amplifier.
· If you connect the Subwoofer output to a powered subwoofer
or a subwoofer amplifier, connect the RCA extension cable to
the Sub Out RCA connector on the J2 Cable Harness.
