Wiring Information (LED models only):
| Wire Size | Wire Color | Use |
| 16 AWG | Red/St ripe | Speaker Positive (+) |
| Black/Stripe | Speaker Negative (-) | |
| 20 AWG | Red | Not Used |
| Green | Not Used | |
| Blue | LED Positive (+) | |
| Yellow | LED Negative (-) |
NOTE: Not all wires may be used in normal applications.
- 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 (412V) 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 pos t.
- 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).
Installation Procedure:
There 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 Lowe r Fixture.
For applications where the cable can be routed through the pipe, the cable can be passed through the opening the bottom of the Lower Fixture. Steps2, 3, an d 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 fixture halves around the pipe.
Adjust the angle of the fixture to the desired position, and mark the location for the cable hole. Remove the fixture assembly, and drill a 5/16″ or 3/8″ hole on the mark. If necessary, use a file 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) 5/16-181-1/4 Machine Screws as pictured. Apply Loctite Red Thread-Locking Compound to each screw end, thread 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.
Slide the excess cable into the opening the pipe as you raise the enclosure to flush the Lower Fixture to the pipe.
Align the two halves of the future around the pipe.
Install (2) 1/4″ Split Lock Washers and (2) 1/4= 20x .1/4 Machine as pictured, and hand tighten them into the fixture. DO NOT FULLY TIGHTEN AT THIS TIME.
Adjust the yaw angle of the enclosure and future assembly to the desired position
Remove one of the 1/4 – 20 x 1-1/4″ Machine Screws at a time. Apply Loctite” Red Thread-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 different 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 #8×1-1/4 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).
