2 Channel Line Output Converter Wiring Diagram

Posted on

The line output converter (LOC) is an essential component of any aftermarket audio system. It allows you to connect your aftermarket amplifier and speakers to the factory head unit without having to cut and splice the wires. For those who want to upgrade their audio systems without having to replace their factory head unit, a line output converter is the perfect solution.

But what exactly is a line output converter? In this article, we will explain what a line output converter is, why you need one, how it works, the different types available, how to install it, and the benefits of using one.

What is a Line Output Converter?

A line output converter (LOC) is an electronic device used to convert a speaker-level audio signal into a low-level signal suitable for use with an amplifier. It consists of several components, including a power supply, inputs, outputs, and a transformer. The power supply is required for the LOC to operate, while the inputs and outputs are used to connect the speakers and amplifier. The transformer is used to convert the speaker-level signal to a low-level signal.

The line output converter is also known as a splitter or signal adapter because it splits the signal from the head unit into two separate signals: one for the speakers and one for the amplifier. This allows the amplifier to process the signal and produce higher levels of sound than the head unit can provide.

Why Do I Need a Line Output Converter?

A line output converter is necessary when connecting an aftermarket amplifier and speakers to a factory head unit. This is because most factory head units are not designed to handle high-level signals from aftermarket amplifiers. If you were to connect an aftermarket amplifier directly to the head unit, it would likely damage the head unit and possibly blow the amplifier’s fuse.

By using a line output converter, you can avoid damaging your factory head unit and ensure that your aftermarket amplifier and speakers are able to produce the sound that you want. A line output converter is also beneficial when upgrading an audio system in an older vehicle, as many of these vehicles do not have pre-amp outputs.

How Does a Line Output Converter Work?

The line output converter works by taking the speaker-level signal from the head unit and converting it to a low-level signal suitable for use with an aftermarket amplifier. This is done through a process known as “attenuation”, which reduces the level of the signal to the correct level for the amplifier. The signal is then sent to the amplifier, where it is processed and amplified before being sent to the speakers.

What Are the Different Types of Line Output Converters?

There are several different types of line output converters available on the market. Some are designed to be used with a single amplifier, while others are designed to be used with multiple amplifiers. There are also different types of transformers available, such as auto-sensing or manual-sensing transformers. Auto-sensing transformers automatically adjust the signal level, while manual-sensing transformers require you to manually adjust the signal level.

The type of line output converter you choose depends on your specific needs and the type of amplifier you are using. You should consult with an audio specialist if you need help choosing the correct line output converter for your system.

How Do I Install a Line Output Converter?

Installing a line output converter is a relatively simple process. You will need to connect the power supply to the line output converter, then connect the inputs and outputs to the head unit and amp. Most line output converters come with detailed instructions, so you should refer to these instructions before attempting to install it yourself.

If you are not comfortable installing a line output converter yourself, you can always take it to a professional audio installer. They will be able to install the line output converter for you and make sure it is working properly.

Can I Install a Line Output Converter Myself?

Yes, you can install a line output converter yourself if you have basic wiring skills. However, it is important to read all of the instructions carefully before attempting to install the line output converter. If you are unsure about any part of the installation process, it is best to seek the advice of a professional audio installer.

What Are the Benefits of Using a Line Output Converter?

The primary benefit of using a line output converter is that it allows you to connect an aftermarket amplifier and speakers to a factory head unit without having to cut and splice the wires. This eliminates the need for complicated wiring, saving you time and money. Additionally, a line output converter protects your factory head unit from damage caused by high-level audio signals.

Do I Need a Line Output Converter for a Factory Head Unit?

Yes, you will need a line output converter to connect an aftermarket amplifier and speakers to a factory head unit. Without a line output converter, you risk damaging your factory head unit due to the high-level audio signals from the amplifier.

What Other Options Do I Have for Integrating an Amplifier with My Factory System?

If you do not want to use a line output converter, there are other options available for integrating an aftermarket amplifier with your factory system. You can install a separate amplifier crossover (often referred to as an active crossover) prior to the amplifier, allowing you to control the frequency range of each speaker individually. You can also use a digital processor, such as a equalizer or sound processor, to tailor the sound to your liking.

No matter which option you choose, it is important to consult with a professional audio installer if you are unsure of the installation process. They will be able to advise you on the best way to integrate an amplifier into your factory system.

A line output converter is an essential component of any aftermarket audio system, allowing you to connect your aftermarket amplifier and speakers to the factory head unit without having to cut and splice the wires. It is important to understand how a line output converter works, the different types available, and how to install it properly. By using a line output converter, you can protect your factory head unit from damage, as well as ensure that your aftermarket amplifier and speakers are able to produce the sound that you want.
