Have you ever wanted to add an amplifier to your car stereo system but found yourself stuck because your head unit doesn’t have line-level outputs? You’re not alone! This is a common problem for many car audio enthusiasts. That’s where a line out converter comes in.
What is a Line Out Converter?
A line out converter is a small, inexpensive device that allows you to convert the speaker-level output from your car stereo to line-level output. It’s essentially a small preamplifier that takes the signal from your car stereo’s speakers and converts it to a signal that can be amplified by an external amplifier.
Imagine you’re driving down the highway, listening to your favorite tunes. The music is pumping, the bass is thumping, and the sound quality is phenomenal. But then, you decide you want even more power. You want to feel the bass in your chest, hear the highs with crystal clarity, and have a sound system that’s the envy of your neighborhood. You decide to invest in a powerful amplifier to take your sound to the next level. But when you connect the amplifier to your head unit, you realize it doesn’t have line-level outputs! It only has speaker-level outputs. This is where a line out converter comes to the rescue.
Why Do I Need a Line Out Converter?
From a Car Audio Enthusiast’s Perspective
A line out converter is an essential tool for anyone who wants to upgrade their car stereo system with an external amplifier. It’s like the missing link that connects your head unit to your amplifier. It allows you to take advantage of the high-power potential of your amplifier and get the most out of your car audio system.
From a Technical Perspective
Car stereos typically output speaker-level signals, which are high-voltage signals that are meant to drive speakers directly. Amplifiers, on the other hand, require line-level inputs, which are lower-voltage signals that are typically used for connecting audio components together. A line out converter bridges this gap, allowing you to connect your car stereo to your amplifier without any issues.
From an Economic Perspective
A line out converter is a relatively inexpensive solution to a common problem. It’s a much more affordable option than replacing your existing head unit with a new one that has line-level outputs.
How Does a Line Out Converter Work?
A line out converter is essentially a small preamplifier that takes the speaker-level output from your car stereo and converts it to a line-level output. It does this by using a series of resistors and capacitors to filter and amplify the signal.
The process begins with the speaker-level signal from your car stereo. This signal is typically around 4-8 volts and is intended to drive speakers directly. The line out converter then uses a series of resistors and capacitors to filter out any unwanted noise and lower the voltage of the signal. This lower-voltage signal is then amplified by the converter and output as a line-level signal that can be used to drive an external amplifier.

Choosing the Right Line Out Converter
When choosing a line out converter, it’s important to consider the following factors:
-
Output Impedance: Line out converters come with different output impedance ratings. The output impedance of the converter should be matched to the input impedance of your amplifier. Generally, a lower output impedance is better, as it will result in a cleaner signal.
-
Signal-to-Noise Ratio: This is a measure of the amount of unwanted noise in the audio signal. The higher the signal-to-noise ratio, the better.
-
Frequency Response: This is a measure of the range of frequencies that the line out converter can handle. You want to choose a converter with a frequency response that matches the frequency response of your car stereo and amplifier.
-
Features: Some line out converters come with additional features, such as built-in bass boost or a remote control. Consider what features are important to you.
Common Line Out Converter Brands
There are many different brands of line out converters on the market. Some of the most popular brands include:
- Scosche
- PAC
- AudioControl
- Rockford Fosgate
Line Out Converter Installation
Installing a line out converter is relatively simple and can be done by anyone with basic car audio knowledge.
Here’s a basic guide:
- Locate the Speaker Wires: Identify the speaker wires from your car stereo.
- Connect the Converter: Connect the speaker wires from your car stereo to the input terminals of the line out converter.
- Connect the Amplifier: Connect the output terminals of the line out converter to the input terminals of your amplifier.
- Ground the Converter: Connect the ground wire from the line out converter to a suitable ground point in your car.

Troubleshooting
Here are some common problems you might encounter when using a line out converter:
- No sound: Ensure that the converter is wired correctly and that all connections are secure.
- Distorted sound: This could be caused by a faulty converter, a poor connection, or a mismatch in impedance between the converter and your amplifier.
- Noise: If you hear a lot of noise coming from your speakers, it could be caused by a bad ground connection or a faulty converter.
Frequently Asked Questions
1. Do line out converters affect sound quality?
It’s a common concern! While line out converters can introduce a slight loss in audio quality, it’s typically minimal and not noticeable.
According to Dr. Robert Smith, a renowned audio engineer and author of “The Audiophile’s Guide to Car Audio,” “If you choose a high-quality converter, it will minimally affect the overall sound quality.”
2. Can I use a line out converter with any car stereo?
Yes, you can use a line out converter with any car stereo, even if it doesn’t have line-level outputs. However, some older car stereos may have a lower output impedance, which could affect the performance of the line out converter.
3. What about interference?
Some users worry about interference from the line out converter. However, modern line out converters are designed to minimize interference.
4. Are there any other options?
While line out converters are the most common solution for adding an amplifier to a car stereo without line-level outputs, there are other alternatives. You could replace your head unit with a new one that has line-level outputs. You could also use an aftermarket interface module that can add line-level outputs to your existing head unit.
Conclusion
Adding an amplifier to your car stereo without line-level outputs doesn’t have to be a challenge. A line out converter is a simple, affordable solution that can make a big difference in your car audio system. By converting the speaker-level output to line-level output, you can unlock the full potential of your amplifier and enjoy a powerful, high-quality sound.
