· Please read the Hardware Guide, this Installation Guide, and the
User Guide before installation and use.
· This Installation Guide is for the TA8 (SEI-ETAMP7700...20) and
TB8 (SEI-ETBAT7700...20) ExtremeTower Speakers. The TA8
Speakers do NOT include a removable, rechargeable battery. You
can purchase the battery separately.
· Only connect a 12V Power Supply to the Amplified Speaker power
input. To prevent damage to the speakers, fire, and/or possible
injury, do NOT connect the BLACK Power Cable to the battery’s
negative (-) terminal until all the installations are completed.
· CAUTION: Do NOT connect to a 24V, 48V or 72V power supply!
The voltage for the power input is +12VDC. You need to connect
to a 12VDC power supply. 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
ExtremeTower directly to higher voltages will cause damage to the
speaker and cause the rechargeable battery to overcharge and
overheat! In extreme cases, excess voltage can cause the battery
to expand, leak, or potentially catch on FIRE! Any damage to the
battery due to improper connections to higher voltages will VOID
THE PRODUCT WARRANTY.
· The Amplified Speaker has a Remote Turn-On Input feature; this
is to ensure that the speaker is completely powered off (no battery
consumption) when your vehicle is not in use. When the Remote
Turn-On Input has a 12V signal, the speaker will turn on or go into
standby, depending on the Power Mode Switch settings. When
there is no input voltage, the speaker will turn off. In general, this
Remote Turn-On signal comes from the vehicle ignition switch
– make sure that the signal voltage on the ignition switch is 12V. If
your vehicle ignition switch signal is not 12V or if you are not able to
get a connection to the ignition switch, you can connect the Remote
Turn-On Wire on the Amplified Speaker to a rocker switch. Then
connect the rocker switch to a 12V power supply or the 12V output
on your voltage convertor. Additionally, some vehicles have a built-in
12V switch panel, which will also work for the Remote Turn-On Wire.

· 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. If loose, please retighten the Locking Screw Latch.
RECOMMENDATION: Do NOT install on your own. This 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 9-pin or 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 electrical tape or heat shrink
tubing. Failing to do this may result in long-term corrosion on the
connection and cause a premature malfunction.
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 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. The Amplified Tower
Speaker has a 9-pin, round connector jack, and the Passive
Tower Speaker has a 6-pin, round connector jack.
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.
The Amplified Tower Speaker has both a 4-pin and a 6-pin,
square connector jack. The Passive Tower Speaker only has
a 6-pin square connector jack.
FM Dipole Antenna Jack
The Amplified Speaker has a built-in FM Antenna. It also includes an
FM Dipole Antenna Jack for an optional external antenna connection
and improved reception (dipole antenna sold separately). If you
prefer to use an external FM antenna, follow these steps:
1. Slowly pull out the rubber cap. Keep the rubber cap attached to
the speaker housing if you plan to remove the antenna periodically;
otherwise, you can remove the antenna cap.
2. Plug your dipole antenna into the FM Dipole Antenna Jack.

Pack to the Amplified Speaker for details), move the (Blue) FM
ANT Switch to the EXT position.
Cables
Your package includes 2 Cable Sets for each wiring option.
1. Aviation Cable Set — For easy running and fishing wires
through a crossbar. The Aviation Cable connection between the
Amplified Tower Speaker and the Passive Tower Speaker uses
the following two cables:
· The long cable (“Round A1” 9-pin to 6-pin pass-through Aviation
Cable) has a 9-pin round connector on one end and 3 bare wires
for power inputs and 6 Bullet connectors on the other end for
interconnection with the Passive Tower Speaker.

will need to connect the 6 bullet connectors from both the long
and short cables and seal the connections to prevent water or
moisture penetration.
2. Deutsch Cable Set —Suggested wiring method if you want to
utilize the Quick-Release-Mount option. The Deutsch Cable
