Are you looking for a way to connect your car audio system to your factory-installed stereo? Look no further than a line out converter (LOC). In this article, we will discuss everything you need to know about LOC wiring diagrams.
What is a Line Out Converter?
A line out converter, also known as an LOC, is a device that converts a speaker-level audio signal to a preamp-level signal that can be used with an aftermarket amplifier. This allows you to upgrade your car audio system without having to replace your factory stereo.
LOCs can also be used to add additional amplifiers to a factory audio system, which can improve the overall sound quality and power output.
How Does a Line Out Converter Work?
A line out converter works by tapping into the factory speaker wires and converting the audio signal to a preamp-level signal using a transformer. The preamp-level signal can then be sent to an aftermarket amplifier to power your speakers or subwoofers.
Most LOCs also include a built-in amplifier remote turn-on wire, which allows the aftermarket amplifier to turn on and off with the factory stereo.
Why Do You Need a Line Out Converter?
Factory-installed car stereos are often limited in their power output and sound quality. By adding an aftermarket amplifier and speakers or subwoofers, you can achieve a much better audio experience.
However, most factory stereos do not have preamp outputs, which are necessary for connecting an aftermarket amplifier. This is where a line out converter comes in – it allows you to connect an aftermarket amplifier to your factory stereo without replacing it.

When wiring an LOC, it is important to follow the manufacturer’s instructions and use the correct wire colors. The table above shows a typical wire color scheme for an LOC installation.
Step-by-Step LOC Wiring Diagram
Here are the basic steps for wiring an LOC:
- Disconnect the negative battery cable from your vehicle’s battery.
- Locate the factory speaker wires in your vehicle. These are usually found behind the stereo, in the doors, or under the seats.
- Strip the insulation off of each wire, being careful not to cut the wires or damage any other components.
- Connect the wires from the LOC to the corresponding speaker wires using butt connectors or solder and heat shrink tubing.
- Connect the power wire from the LOC to a 12V power source and the ground wire to a clean, bare metal surface on the vehicle’s chassis.
- Connect the remote turn-on wire from the LOC to the amplifier remote turn-on wire on your aftermarket amplifier.
- Reconnect the negative battery cable and test the system to ensure everything is working properly.
FAQ
What is the difference between a LOC and a speaker-level input on an amplifier?
A speaker-level input on an amplifier is designed to accept a speaker-level audio signal directly from the factory stereo, without the need for an LOC. However, most speaker-level inputs are not as robust as an LOC, and may not provide the same level of signal conditioning or noise filtering.
Can I use an LOC with a factory subwoofer?
Yes, an LOC can be used to connect an aftermarket amplifier to a factory subwoofer. The wiring will typically be similar to a standard four-channel setup, with the subwoofer wires tapped from the rear speaker wires.
Can I install an LOC myself?
Yes, an LOC can be installed by a DIY enthusiast with basic electrical knowledge and tools. However, if you are not comfortable working with electrical systems, it is recommended that you seek the assistance of a professional installer.
Can an LOC cause damage to my factory stereo or aftermarket amplifier?
If installed properly, an LOC should not cause any damage to your factory stereo or aftermarket amplifier. However, improper installation or use of an incorrect LOC can cause damage to your audio system, so it is important to follow the manufacturer’s instructions and use high-quality components.
What should I do if I hear noise or interference in my audio system after installing an LOC?
If you hear noise or interference in your audio system after installing an LOC, there are several things you can try:
- Check your wiring connections to make sure they are secure and properly insulated.
- Move the LOC away from other electrical components in your vehicle, such as the alternator or ignition system.
- Install a noise filter or ground loop isolator between the LOC and the amplifier.
- If all else fails, consult a professional installer or audio technician for assistance.
Conclusion
A line out converter is a valuable tool for upgrading your car audio system without replacing the factory stereo. By following the manufacturer’s instructions and using the correct wiring diagram, you can enjoy a better audio experience in your vehicle.
If you have any questions or concerns about LOC wiring diagrams or installation, feel free to ask a professional installer or audio technician for assistance.
