· Please read the Hardware Guide and User Guide before
installation and use.
· When mounting the speaker, it is extremely important to make
sure that the mount is secure and will not cause any potential
issues. Please check that the speaker does NOT block the
driver’s view or prevents the safe operation of your boat or
other vehicle. Ensure that all screws are tightened and the
speaker is secured correctly so that the speaker will NOT fall.
· It is highly recommended to periodically check that the mount is
secured. Retorquing the mounting bolts may be necessary.
RECOMMENDATION: Do NOT install on your own as
installation is a two-person job, to be done safely. Please be
careful to ensure no personal injury or damage to your vehicle.
· An Aviation Connector Jack Cap comes attached to the
Base-Mount on each speaker. If you choose to use the
Deutsch Cable Set for wiring, you MUST screw the cap into the
unused Aviation Connector Jack on each speaker, tightening
it clockwise with a long nose plier (not included) or similar
tool. Failing to do this may result in potential water or moisture
penetration into the jack connector pins, cause damage to the
speaker, and VOID THE PRODUCT WARRANTY.
· When you connect the 6-pin Aviation Connector to the
Aviation Connector Jack in the Base-Mount, you MUST
ensure the connector is tightened (clockwise) so that the
connection is waterproof.
· 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 electric tape or heat shrink tubing
(not included). Failing to do this may result in long-term corrosion
on the connection and cause a premature malfunction.

Audio and LED Control Connectors and Cables
Audio and LED Lighting Control Connections: The ExtremeTower
Speakers have 5 input connections / wires.
· 3 LED control inputs to connect to an external SoundExtreme
LEDCast-enabled controller or LEDCast Radio (sold separately).
· 2 audio inputs (Positive + and Negative -) to connect to an external
audio power amplifier or radio.
Speaker Connector Jacks: Each speaker has 2 types of
Connector Jacks.
1. A round Aviation Connector Jack is inside the speaker
Base-Mount, which allows the cable to pass through the
Bottom Mount Clamp and go into a hole in the crossbar at the
location where the speaker is mounted.
2. A square Deutsch Connector Jack is behind the speaker
Base-Mount underneath a rubber cap. This is for an installation
where the wire is installed outside of the tower / roll cage.
This is also the connection suggested if you want to utilize the
Quick-Release-Mount option.

3. LED Extension Cable — Depending on the distances between
your speakers, the audio source, and the LED lighting controller,
you may need to use the provided LED Extension Cables.
For the LED Extension Cable, connect the 3-pin male connector
on the Aviation (Round C) Cable or Deutsch (Deutsch C) Cable
to the 3-pin female connector on the included LED Extension
Cable. Align the arrow on both connectors, push-in, and screw
the nut cap on the female connector.
Make sure the cable does NOT touch any moving parts on the
vehicle. If the cable is longer than required, do NOT cut the cable
and reconnect. Instead, wrap the extra length on your vehicle and
fasten the cable with zip ties. Please ensure the cable does NOT
touch or drag on the ground AND is safely secured to prevent it
from coming into contact with any moving parts.
A speaker audio extension cable is NOT included in the package.
Obtain a high-quality, marine speaker cable with your required
length. 16 AWG speaker cable is recommended. When you
connect the cables, make sure the connections are sealed
(e.g., with the included electrical tape) to prevent potential wire
corrosion due to water or moisture penetration.

Installation and Wiring
Installation and Wiring Procedure 1:
Round Aviation Cable
If you choose to use the Aviation Cable Set for wiring your
ExtremeTower Speakers, follow the steps below.
Speaker and LED Lighting Control Wiring: The Aviation Cable will
pass through the Bottom Mount Clamp and go into a hole in the
crossbar; therefore, it is necessary to run the speaker wires and
connections before the speakers are mounted onto the crossbar.
1. Find or drill a hole in the crossbar at the spots where each speaker
will be mounted.
2. Fish the (“Round C” 6-pin pass-through LED and speaker) Aviation
Cable into the hole in the crossbar where the ExtremeTower
Speaker will be mounted and fish the wires through the crossbar
to the location where your audio amplifier and/or the LED light
controller is located. The included 3-Pin LED Extension Cables
and speaker audio extension cables (not included) may be needed
to reach the amplifier and controller.
Mount the Tower Speaker to the Crossbar
1. Base-Mount: Remove the tape and pull out a small plastic bag
from the Base-Mount. This bag has one Aviation Connector Jack
Cap. You don’t need this cap for this installation, but save the cap
for later use in case you change the wiring methods.

2. Put the appropriate Lower Rubber
Insert onto the Swivel Flange and
Bottom Clamp Assembly.
3. Fish the (“Round C” 6-pin pass-
through LED and speaker) Aviation
Cable through the inner hole of the
Swivel Flange and Bottom Clamp
Assembly, and the Base Cover Plate.
4. Connect the (6-pin round) Aviation Connector to the Aviation
Connector Jack on the speaker. Tighten the connector clockwise
with a long nose plier (not included) or similar tool.
IMPORTANT: Tighten the connector to ensure the connection is
waterproof to avoid potential water or moisture penetration into
the jack connector pins, causing damage to the speaker.
5. Fish the cable into the hole in the crossbar where the Tower
Speaker will be mounted and fish the line through the crossbar
and go to the location where your audio amplifier and LED light
