Introduction
Important
· Please read the User Guide before installation and use.
· Your SoundExtreme Elite soundbar (referred to as SE28) requires
a 12V DC voltage power input. If your vehicle battery power output
is not 12V (e.g., 24V, 36V, or 48V), you will need a voltage converter
with 12V output (e.g., a 48V-to-12V converter). Connecting
the SE28 directly to higher voltages will cause damage to the
soundbar and VOID THE PRODUCT WARRANTY.
· Please use the included 12 AWG cable with the 25A Fuse to
connect your SE28 to your power supply. The wiring harness for
the previous generation of ECOXGEAR soundbars was a 14 AWG
cable with 15A Fuse – this harness is NOT compatible with the
SE28 speaker.
· The Amplified ExtremeTower Speaker is compatible with the
ECOXGEAR audio and LED lighting EcoSystem, which includes
LEDCast and EcoCast Innovations. Look for the LEDCast
and EcoCast logos on the growing family of ECOXGEAR and
SoundExtreme audio and lighting solutions. EcoCast-enabled
audio products are designed to be paired with one or more
EcoCast-enabled products. Simply initiate EcoCast Transmitting
Mode in one SoundExtreme or ECOXGEAR speaker and
broadcast your music to one or more EcoCast-enabled products
in Receiving Mode.
· The SE28 has an integrated LED lighting controller with two
outputs (Zones). 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 brand LEDs. It may cause permanent
damage to the product and void the warranty.
· Each time you provide power to your SE28, the speaker will
enter the Power State that the speaker was in before power was

5
Introduction
removed – the soundbar will either turn o (Standby Mode) or
turn on – i.e., the speaker functions similarly to your car radio. The
SE28 has 3 power states: Power On, Standby, and Power O. The
Power State functionality depends on whether the SE28 is directly
connected to a vehicle’s 12V battery or through a switch (the SE28
connects to a switch, and the switch connects to the 12V battery):
· If your SE28 is directly connected to a vehicle’s 12V battery,
pressing the Power Button on the speaker or on the Remote
Control will turn on the speaker or turn o the speaker (i.e. put
speaker into Standby Mode where the speaker consumes
minimal power). As the SE28 keeps a power connection to
the 12V battery, this scenario does NOT have a complete
power o state.
· If the SE28 is connected to a vehicle’s 12V battery through a
switch, there are two scenarios:
i. If the switch is turned o, the SE28 is powered o.
ii. If the switch is on, pressing the Power Button on the speaker
or on the Remote Control will turn on the speaker or put the
speaker into Standby Mode.
· LED lights are known to create interference (noise) on some FM
radio frequencies (stations). When you tune or seek a station, it is
recommended that you turn the LED Party Lights off.
CAUTION: After taking the product out of the polyethylene bag,
be sure to dispose of the polyethylene bag out of the reach of
children. Children may play with the bag, which could result in the
child’s suffocation.

Speaker LEDs, Light Bar, Utility Light and LED Light
Control Outputs
The SE28 soundbar has an integrated LEDCast lighting controller to
support the built-in addressable LED Party Lights and Utility Light on
the soundbar and two external LEDCast enabled LED products. The
LED Party Lights driven by the integrated controller provide millions
of Color Modes: solid colors, fading, jumping, chasing, speed, and
variable brightness.
· There are RGB LED Party Lights behind the 4 mid-range
Speakers on the front, the 2 Woofers on each side, and rear-
facing LED Light Bar.
· Additionally, the rear-facing Light Bar can also be used as a
white Utility Light, which provides 3 levels of brightness: high,
mid, and low.
Note: The RGB LED Light Bar and Utility Light are co-located
on the same Light Bar on the back; as such, the Light Bar cannot
function as a white Utility Light and RGB LED Party Lights at the
same time. Refer to Light Bar: Utility Light and Zone 2 RGB LED
Party Lights for more details.
· The SE28 supports two external LEDCast-enabled LED products,
each has a maximum 5A DC output. Refer to LED Lighting Control
to External LEDs and LED Lighting Zones, Modes, and Scenes
for more details.

Installation and Wiring
Mounting Your Soundbar
1. To mount the speaker, first place
the 2 Mounts on the ends of the
SoundExtreme at your desired
orientation and attach them using
three or four (depending on the
orientation of your mount) Button
Head Bolts, each. Tighten securely.
2. Ensure that the speaker fits
in the desired location and
mark where the mounts will be
attached to your vehicle.
3. Drill holes at the desired mounting
points on your vehicle, large enough
for the provided ¼-20 Bolts to fit.
4. Place the Rubber Feet on
both Mounts.
5. Attach the Mounts to your vehicle
with the provided ¼-20 Bolts and
Nuts. Tighten securely.
Tip: Alternatively to drilling holes into
your vehicle, you can also use the
provided Worm Clamps to secure the
speaker to your vehicle. In order to
prevent scratching /damage to your
vehicle, slide the provided rubber
sleeves onto the worm clamps before
securing the speaker.
Note: For high-speed, high-vibration,
and high-impact applications, we
recommend using the provided ¼-20
Bolt mounting solution, detailed above. Check out other mounting
accessories at www.soundextreme.us.

Installation and Wiring
Connecting to 12V DC Power Supply
IMPORTANT: Please use the included 12 AWG cable with the 25A
Fuse to connect your SE28 to your power supply. The wiring harness
for the previous generation of ECOXGEAR soundbars is NOT
compatible with this speaker.
The SE28 does NOT have an internal battery. It MUST be
connected to an external 12V DC power supply to function. When
you install the SE28 to a battery or a voltage regulator on a golf cart,
a boat, a quad bike, a UTV, or another vehicle, you need to make
sure that your vehicle battery or battery pack terminal voltage is
12VDC. If the battery terminal voltage is not 12V, you will need a
DC-DC converter with a 12V output and 25A capacity. Connecting
the SE28 to a non-12VDC power source will lead to a malfunction or
damage to the speaker.
WARNING: Even when powered o, the SE28 will continue to draw
minimal power from your battery. To prevent draining your battery
when your SE28 or powersports vehicle are not in use for more than
48 hours, unplug the SE28 from the battery or add a 25A toggle
switch. (Toggle switch sold separately.)
Installation: 12V Power-In SAE Connector
1. Attach the 8ft Power Cable to the 12V Power-In SAE Connector.
Use Caution: Do NOT connect to 12V Battery if the Power-In
SAE Connector is wet. Contact may cause electric shock and
injury if wet.
