Safety Considerations
• Do not mount in areas of extreme heat.
• Ensure this product is securely installed so
that it does not come loose in the event
of a collision/sudden jolt or from repeated
vibrations during normal operation.
• Do not run system wiring outside or
underneath the vehicle/vessel. This is an
extremely dangerous practice, which can
result in severe damage/injury.
• Check before drilling to make sure that you
will not be drilling into a fuel tank, gas/brake
line, wiring harness, or other vital system.
• Secure all wiring as needed, using cable ties
or wire clamps to protect them from moving
parts and sharp edges.
Make sure to carefully plan the routing of the
remote’s connection cables prior to cutting
or drilling any panels.
4. Connect the cables and place the
MMR-5N2K into the opening.
Secure the MMR-5N2K using the two (2)
supplied mounting screws.
5. With the JL AUDIO logo of the trim ring
positioned at the top (12 o’clock), press the
trim ring onto the front of the MMR-5N2K.
6. Align the keyed opening of the
volume knob with the shaft of the
MMR-5N2K and press on firmly.
Mounting & Installation
The MMR-5N2K is designed for front-mounting
in flat panels, requiring just a single, 1.5-inch
(38 mm) hole for installation. Desired mounting
locations should have at least 2.35-inches (60
mm) square of flat surface area, along with
adequate rear space for the controller body and
access to make connections.
1. Select a suitable mounting location and cut
a 1.5-inch (38 mm) hole using an appropriate
tool/hole saw.
2. Place the MMR-5N2K into the opening, with
the alignment arrow pointing up (12 o’clock)
and mark the surface for drilling pilot holes.
3. Drill two (2) appropriately sized pilot holes in
the mounting surface at the pilot hole marks.

IPX7 Water Resistance Rating
This product has been tested to withstand immersion in water, up to
1 meter (3.28 ft.) deep, for up to 30 minutes (when properly installed).
Note: While designed to be water resistant, this product should never be
submerged under water for prolonged periods or subjected to activity
that creates pressure on it that exceeds its depth rating.
