Are you looking to upgrade your car’s audio system with a powerful subwoofer? If so, you’ll need to hook up a line output converter (LOC) to connect your subwoofer to your car’s stereo system. In this article, we’ll take you through the step-by-step process of hooking up a line output converter for subwoofer, and provide you with some valuable tips and tricks to ensure a successful installation.
What is a Line Output Converter (LOC)?
A line output converter (LOC) is an electronic device that converts the high-level signal from your car’s stereo system to a low-level signal that can be used to power a subwoofer. The LOC is necessary because most car stereos are not designed to power subwoofers directly. The LOC takes the high-level signal from the stereo’s speaker outputs and converts it to a low-level signal that can be used to power the subwoofer amplifier.
Why Do You Need a Line Output Converter?
You need a line output converter for several reasons:
- To match the impedance: The impedance of your car’s stereo system is not compatible with the impedance of the subwoofer. The LOC helps to match the impedance of the two systems, ensuring that the signal is transmitted efficiently.
- To increase the signal strength: The LOC amplifies the signal from the stereo system, ensuring that it is strong enough to power the subwoofer.
- To prevent damage to the stereo system: If you connect the subwoofer directly to the stereo system without an LOC, you risk damaging the stereo system. The LOC protects the stereo system from the high power requirements of the subwoofer.
Choosing the Right Line Output Converter
Not all line output converters are created equal. When choosing an LOC, consider the following factors:
- Power handling: Choose an LOC that can handle the power requirements of your subwoofer. A higher power handling capacity ensures that the LOC can handle the high power requirements of the subwoofer.
- Frequency response: Choose an LOC with a frequency response that matches the frequency response of your subwoofer. A wider frequency response ensures that the LOC can handle the low-frequency signals produced by the subwoofer.
- Input sensitivity: Choose an LOC with an input sensitivity that matches the output level of your car’s stereo system. A higher input sensitivity ensures that the LOC can handle the high-level signal from the stereo system.
Types of Line Output Converters
There are two types of line output converters:
- Passive LOC: A passive LOC uses a transformer to convert the high-level signal to a low-level signal. Passive LOCs are simple and inexpensive but may not provide the best sound quality.
- Active LOC: An active LOC uses an amplifier to convert the high-level signal to a low-level signal. Active LOCs provide better sound quality and are more expensive than passive LOCs.
Hooking Up the Line Output Converter
Hooking up the line output converter is a relatively simple process. Here’s a step-by-step guide:
- Connect the LOC to the stereo system: Connect the LOC to the stereo system’s speaker outputs. Make sure to connect the LOC to the correct outputs (e.g., rear left and right).
- Connect the LOC to the subwoofer amplifier: Connect the LOC to the subwoofer amplifier’s input. Make sure to connect the LOC to the correct input (e.g., RCA input).
