• For marine installations, do not connect the speaker’s LED lights to the vessel’s
navigational lighting circuits.
• For short-circuit protection, install a supplied fuseholder onto EACH speaker’s BLUE (+12V)
LED power connection lead.
• Connect all BLUE (+12V) leads together (parallel) and connect to a switched +12V supply.
Connect all YELLOW (GND) leads together and connect to a negative ground or to the
NEGATIVE battery post.
• We recommend activating the speakers’ LEDs thru a lighting circuit that supplies +12V via
an existing switch. If an existing switched circuit is not available, you may install a dedicated
toggle/rocker style switch that will supply positive (+12V) power. Fuse this connection
according to how many LED circuits you have (LED circuits x 150 mA).
Example: Onespeaker pair of
LED circuitsconnected in parallel.
NOTE: Not all wires may beused in normal applications.
Example: Two speaker pairsof
LED circuitsconnected in parallel.

ere are two speaker cable routing options. For
applications where the cable cannot be routed
through the pipe, the cable can be passed through
one of the openings on the side of the Lower Fixture.
For applications where the cable can be routed
through the pipe, the cable can be passed through
the opening in the bottom of the Lower Fixture.
Steps 2, 3, and 6 are only necessary for this option.
Determine the speaker mounting location. Slide a
1/4" Split Lock Washer over each of the four 1/4 - 20
x 1-1/4” Machine Screws, and hand tighten the
screws into the Lower Fixture to temporarily secure
the two xture halves around the pipe.
Adjust the angle of the xture to the desired position,
and mark the location for the cable hole. Remove the
xture assembly, and drill a 5/16" or 3/8" hole on the
mark. If necessary, use a le or sandpaper to smooth
the edges to ensure no sharp edges.
Align the Lower Fixture to the enclosure. Install (2)
5/16" Split Lock Washers and (2) 5/16 - 18 x 1-1/4”
Machine Screws as pictured. Apply Loctite® Red
read-Locking Compound to each screw end,
them into the Lower Fixture, and fully tighten while
pressing down on the Lower Fixture to ensure no gap.
Have a helper support the enclosure during this
step. Connect the 16 AWG red/stripe (+) and black/
stripe (-) speaker cable exiting the ETXv3 enclosure
to the speaker cable exiting the pipe. For LED
models, connect the 20 AWG blue LED (+) and
yellow LED (-) as illustrated on Page 2.

Installation Procedure:
thread

Slide the excess cable into the opening in the pipe as
you raise the enclosure to ush the Lower Fixture to
the pipe.
Align the two halves of the xture around the pipe.
Install (2) 1/4" Split Lock Washers and (2) 1/4 - 20 x
1-1/4" Machine Screws as pictured, and hand tighten
them into the xture. DO NOT FULLY TIGHTEN AT
THIS TIME.
Adjust the yaw angle of the enclosure and xture
assembly to the desired position.
Remove one of the 1/4 - 20 x 1-1/4" Machine Screws
at a time. Apply Loctite® Red read-Locking
Compound to the screw end, reinstall, and fully
tighten. Repeat the process for the other three
screws.
Remove adhesive backing and install the JL Audio
logo badge (Sport Grille Models Only).
If a dierent speaker angle is desired, remove the #8
x 1-1/4" Pan Head Screws and #8 Flat Washers
securing the speaker in the enclosure.

Rotate the speaker to the desired angle. Reinstall the
#8 x 1-1/4" Pan Head Screws and #8 Flat Washers.
For best adhesion, it is recommended to clean the
inside of the aluminum cap with acetone (not
included) prior to attaching it to the enclosure. Apply
a circular bead of Silicone Adhesive to the inside of
the aluminum logo cap, about 1/2-inch (13 mm)
from the outer edge.
Align the aluminum logo cap to the desired angle of
rotation, and press it onto the back of the enclosure.
Apply masking tape (not included) to hold the cap in
place until the silicone cures (at least 24 hours).
