Car Audio Line Out Converter A car audio line out converter is a device used to convert a high-level speaker signal into a low-level signal that an amplifier or other audio equipment can use. This is a common problem in car audio systems where the factory radio or head unit has no preamp outputs. The line-out converter is typically installed between the head unit and the amplifier and can provide a clean and reliable signal for the amplifier to work with. Some benefits of using a line out converter include improved sound quality, increased volume control, and the ability to add aftermarket components to your car audio system.
