Installation Applications
This product is designed for operation in
12 volt, negative-ground electrical systems.
Using this product in systems with positive
ground and/or voltages other than 12 volts
may result in damage to the product and
will void the warranty. This product is not
certified or approved for use in aircraft.
Safety Considerations
• Whenever possible, mount this product
in a dry, well-ventilated location that does
not interfere with other factory installed
electronic devices. If a dry environment is
not available, a location that is not exposed
to heavy splashing may be used.
• While this product is designed to be water-
resistant, it should never be submerged
under water or subjected to high-pressure
water spray.
• Do not mount in an engine compartment
or in any 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 as a result of repeated
vibrations during normal operation.
• Check before drilling to make sure that you
will not be drilling into an exterior panel/
hull, fuel tank, gas/brake line, wiring harness,
or other vital system.
• Do not run system wiring outside or
underneath the vehicle/vessel. This is an
extremely dangerous practice, which can
result in severe damage/injury.
• Protect all system wires from sharp
edges (metal, fiberglass, etc.) by carefully
routing them, tying them down and using
grommets and loom where appropriate.
• Secure all wiring as needed, using cable
ties or wire clamps to protect them from
moving parts and sharp edges.
• Do not replace the power wire fuse with one
of a different value. Never bypass the fuse.
Mounting & Installation
The design of the MBT-CRX requires just
a single hole for installation. Its easy-to-
use threaded-collar mounting system can
accommodate installations in flat surfaces up
to 1.75 inches (4.5 cm) thick. A front-mounted
adaptor plate is included for installations in
panels exceeding 1.75 inches (4.5 cm) thick,
or where rear access is limited or not possible.
Refer to the diagrams below for your specific
mounting application.

Wiring Diagram
Pairing Your Device
(required for operation)
1. Ensure your streaming device has Bluetooth®
enabled and that the MBT-CRX is on (backlit
in blue). The JL Audio logo on the MBT-CRX
will blink to indicate it is in pairing mode.
2. Within your streaming device’s Bluetooth®
setup menu, select “MBT-CRX” from the list
of pairable devices.
3. When successfully connected, the
JL Audio logo on the MBT-CRX will stop
blinking and remain lit. A single beep will be
heard through the connected audio system.
Note: If optional connection is made to a head
unit’s remote turn-on output, the head unit
will turn the MBT-CRX on/off and the MBT-CRX
power button will no longer operate.
Pairing Considerations cont’d
When a connected streaming device is out of
range for more than one minute, the MBT-CRX
will automatically disconnect this streaming
device and return to pairing mode (JL Audio
logo will blink). When that same device comes
back into range, it should be reconnected to
the MBT-CRX manually.
Controlling Audio Playback
Once connected, use the controls on the
MBT-CRX to adjust volume up/down, track
selection and play/pause.

Pairing Considerations
Multiple devices can be paired to the MBT-CRX,
but only one streaming device can connect at
one time.
The MBT-CRX will remember the last device
that was connected to it and reconnect with
it automatically. If that streaming device is not
active, then other paired streaming devices can
connect manually, or new streaming devices
can be paired.
