Are you looking for a way to improve your car audio system without having to replace your factory stereo? If so, a line output converter (LOC) might be the solution you’re looking for. In this article, we’ll focus on the Metra Line Output Converter LLC1 and its wiring diagram. We’ll provide you with a step-by-step guide on how to install it and answer some frequently asked questions about LOCs.
What is a Line Output Converter (LOC)?
A line output converter is a device that allows you to add an aftermarket amplifier to your car’s factory audio system. It converts the speaker-level output from your factory stereo into a preamp-level signal that can be fed into your amplifier. This signal is cleaner and stronger than the noisy signal that comes directly from your factory stereo, resulting in better sound quality.
The Metra Line Output Converter LLC1 is one of the most popular LOCs on the market. It’s designed to work with most factory stereos and amplifiers, and it’s relatively easy to install.
Why Do You Need a Line Output Converter?
If you’re planning on installing an aftermarket amplifier in your car, you’ll need a line output converter. Most factory stereos don’t have preamp outputs, which are necessary to connect an amplifier. Instead, they have speaker-level outputs that are intended to drive the speakers directly. These outputs are usually low-powered and susceptible to noise and distortion.
By installing a line output converter, you’ll be able to tap into the speaker-level signal and convert it into a clean, preamp-level signal that can be sent to your amplifier. This will result in better sound quality, more power, and better control over your speakers.
What is the Metra Line Output Converter LLC1?
The Metra Line Output Converter LLC1 is a compact device that converts speaker-level signals into preamp-level signals. It has two channels, so it can be used to connect two amplifiers. It also features a remote turn-on wire, which allows you to turn your amplifier on and off with your factory stereo.
The LLC1 is designed to work with most factory stereos and amplifiers, and it’s relatively easy to install. It comes with a wiring harness and instructions, which we’ll discuss in the next section.
How to Install the Metra Line Output Converter LLC1
Installing the Metra Line Output Converter LLC1 is a relatively straightforward process. Here’s a step-by-step guide:
Step 1: Disconnect Your Battery
Before you start working on your car’s electrical system, it’s important to disconnect the battery. This will prevent you from accidentally shorting anything out or damaging your car’s electronics.
Step 2: Remove the Factory Stereo
The first step in installing the LLC1 is to remove your factory stereo. This will give you access to the wiring harness, which you’ll need to connect the LOC.
The process for removing your stereo will vary depending on your car’s make and model. In general, you’ll need to use a trim removal tool to pry off any panels around the stereo, and then remove any screws or clips that are holding it in place. Once you’ve removed the stereo, you should see the wiring harness at the back.
Step 3: Connect the Wiring Harness
The LLC1 comes with a wiring harness that you’ll need to connect to your factory stereo’s wiring harness. The LLC1’s harness has four wires: two for the left channel and two for the right channel.
You’ll need to find the wires that correspond to your car’s left and right speaker outputs. In most cases, these wires will be color-coded. Once you’ve located them, you’ll need to splice the LLC1’s harness into the factory harness using wire connectors or crimp connectors.
Step 4: Connect the Remote Turn-On Wire
The LLC1’s remote turn-on wire needs to be connected to your factory stereo’s wiring harness as well. This wire is usually blue or blue with a white stripe.
Find the wire that corresponds to your stereo’s remote turn-on output and splice it into the LLC1’s remote turn-on wire using a wire connector or crimp connector.
Step 5: Connect the RCA Cables
The final step in installing the LLC1 is to connect the RCA cables. The LLC1 has two RCA outputs: one for the left channel and one for the right channel. You’ll need to connect these outputs to the RCA inputs on your amplifier.
Once you’ve connected the RCA cables, you can go ahead and reinstall your factory stereo. Make sure to test your audio system before putting everything back together.
FAQ
How Do I Know If I Need a Line Output Converter?
If you’re planning on installing an aftermarket amplifier in your car and your factory stereo doesn’t have preamp outputs, you’ll need a line output converter. However, even if your stereo does have preamp outputs, you may still need a line output converter if you want to keep your factory stereo and add an amplifier.
Can I Install a Line Output Converter Myself?
Yes, you can install a line output converter yourself if you have basic electrical knowledge and some tools. However, if you’re not comfortable working with car audio systems, it’s best to have a professional install it for you.
What’s the Difference Between a Line Output Converter and a High-Low Converter?
A line output converter and a high-low converter are the same thing. They both convert speaker-level signals into preamp-level signals.
What’s the Difference Between a Passive and Active Line Output Converter?
A passive line output converter doesn’t require any external power source, while an active line output converter does. An active line output converter is generally more expensive, but it provides cleaner and stronger signals.
Can I Use One Line Output Converter for Two Amplifiers?
Yes, you can use one line output converter for two amplifiers. However, you’ll need to make sure that the LOC is capable of driving two amplifiers and that you’re using a Y-splitter cable to connect the two amplifiers.
Conclusion
The Metra Line Output Converter LLC1 is a great way to add an aftermarket amplifier to your car’s factory audio system. It’s easy to install, and it provides cleaner and stronger signals than your factory stereo’s speaker-level outputs. By following the steps in this article, you should be able to install the LLC1 and improve your audio system’s sound quality. If you have any questions or need further assistance, feel free to reach out to a car audio professional.
