The Line Output Converter, or LOC for short, is an essential device for any car audio enthusiast. It allows you to take the output from your factory radio and convert it into a signal that can be sent to your aftermarket amplifier. In this article, we'll explain what a LOC is, why you need one, how it works, how to install it, and any alternatives you may have.
What is a Line Output Converter?
A line output converter is a device that converts the low-level signal from your car stereo to a line-level signal, which is compatible with most aftermarket amplifiers. The LOC is designed to be installed in between the head unit and the amplifier. It will convert the speaker-level output from the head unit to a low level signal that can be used by most aftermarket amplifiers or subwoofers.
Why Do You Need a Line Output Converter?
In order to get the best sound quality from your car audio system, you need to make sure that all of your components are working together seamlessly. Your aftermarket amplifier needs a low-level signal to produce the best quality sound. Without a LOC, the head unit's signal will be too high for the amplifier to accept. That's why it's important to use a line output converter.
How Does a Line Output Converter Work?
The line output converter performs two functions: it reduces the output level of the head unit so that it is compatible with the amplifier, and it also performs signal processing. This processing includes equalization (EQ), crossover filtering, and other adjustments that allow you to tailor the sound of your system. Without the proper signal processing, your system will not sound as good as it could.
How Do You Install a Line Output Converter?
Installing a line output converter can be a bit tricky, so it’s best to consult a professional if you’re unsure. Generally speaking, you’ll need to connect the wires from the head unit to the LOC, then connect the LOC to your amplifier. You’ll also need to attach the power wires to the appropriate locations. Once the LOC is connected, you’ll need to make the necessary signal processing adjustments to get the best sound.
Can I Install a Line Output Converter Myself?
Yes, it is possible to install a line output converter yourself if you’re familiar with car audio systems. However, it’s best to consult a professional if you’re not sure what to do. In some cases, it may be necessary to access the factory wiring or modify the wiring in order to install the LOC. If you’re not sure about any of these steps, it’s best to have a professional handle the installation.
What Tools Do I Need to Install a Line Output Converter?
You’ll need a few basic tools in order to install a line output converter. You’ll need a pair of wire strippers and crimpers for cutting and splicing the wires, a screwdriver for mounting the LOC, and a multimeter for testing and troubleshooting. It’s also a good idea to have a set of side cutters and a soldering iron on hand, just in case.
Where Should I Install the Line Output Converter?
The line output converter should be installed as close to the head unit as possible. This will ensure that the signal is as strong as possible and that the signal processing is performed correctly. It’s best to mount the LOC in the trunk or under the seat, but you may need to install it in the dash if there is no room elsewhere.
How Do I Connect the Line Output Converter to the Rear Speakers?
The line output converter can be connected to the rear speakers by connecting the output terminals on the LOC to the input terminals on the amplifier. Depending on the model of your LOC, you may need a signal cable or a pair of RCA cables. Be sure to follow the instructions provided with your LOC for the best results.
Are There Any Alternatives to Using a Line Output Converter?
If you don’t want to use a line output converter, there are a few alternatives. Some head units come with a built-in line output converter, so you won’t need to buy one separately. You can also buy an adapter cable that will convert the speaker-level output from the head unit to a line-level signal that can be used with most aftermarket amplifiers. Finally, there are aftermarket head units that will accept both speaker-level and line-level inputs, eliminating the need for a LOC altogether.
In conclusion, a line output converter is a must-have for any car audio system. It allows you to get the best sound quality out of your components by converting the head unit’s signal to a line-level signal that is compatible with aftermarket amplifiers. Installing a LOC can be tricky, so it’s best to consult a professional if you’re not sure how to proceed. Alternatives such as adapter cables and head units with built-in line output converters are available, but they may not provide the same level of performance as a dedicated LOC.
