Installation Applications
This product is designed for operation in vehicles with 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
• Install this product in a dry, well-ventilated location that does not interfere with your
vehicle’s safety equipment (air bags, seat belt systems, ABS brake systems, etc.).
• Securely mount this product so that it does not come loose in the event of a
collision or sudden jolt to the vehicle.
• Check before drilling to make sure that you will not be drilling into a gas tank,
brake line, wiring harness or other vital vehicle system.
• Do not run system wiring outside or underneath the vehicle. This is an extremely
dangerous practice, which can result in severe damage/injury.
• Use good quality crimp connectors (or solder with heat shrink tubing) when
making connections to a vehicle’s electrical system.
• Take the necessary precautions when making connections to the vehicle’s battery.
• Protect all system wires from sharp metal edges and wear by carefully routing
them, tying them down and using grommets and loom where appropriate.
Failure to do so may result in a dangerous short circuit.
Planning Your Installation
It is important that you take the time to read this manual and that you plan
your installation carefully. It is very easy to damage expensive vehicle systems
in modern automobiles. Never assume that you have found appropriate wires
without consulting a reliable wiring diagram or without performing signal testing
with proper test equipment. If you are uncomfortable or unfamiliar with reading
diagrams or testing signals, please enlist the services of your authorized JL Audio
dealer to perform the installation.
Product Description
The LoC™ 22 is an active two-channel processor engineered

compatibility with most analog outputs from OEM source units and amplifiers
3. Dual range input load switch for maximum compatibility with OEM amplifiers
4. One stereo pair of crystal-clear, line-level RCA output jacks (up to 8V RMS)
5. Automatic turn-on via DC-Offset or Signal-Sensing
6. A dedicated 12V remote turn-on output to activate
aftermarket signal processors or amplifiers (similar to an
aftermarket head unit’s remote turn-on lead)
7. Onboard LED clipping indicator for quick & easy output level setting
What’s Included
(1) LoC™ 22 Line Output Converter
(1) 3-pin Power Connector plug
(1) 4-pin Input plug
(1) User manual
Installation Procedure/Making Connections
The LoC™ 22 uses removable plugs for making power and input signal
connections. Receptacles in each plug accept up to 16 AWG wire. To attach wires,
remove the plugs from the LoC™ 22 and use a small flathead screwdriver to back
out the set screws. Strip 1/4 inch (6 mm) of insulation from the end of each wire
and insert the bare wire into the receptacle, seating it firmly so that no wire is
exposed. While holding each wire in place, tighten the set screw firmly, taking care
not to strip the head of the screw.
Use caution to ensure correct polarity and wire placement of the Power and
Input signal connections.
Make sure to observe proper orientation when inserting the plugs into the
LoC™ 22. Each plug is keyed to fit in one direction only. When inserted
correctly, the set screws should be facing up.
