Are you trying to upgrade your car audio system and need to install a line out converter? A line out converter is a device that connects to your car’s factory radio and converts the speaker level outputs into a preamp level signal that can be used with aftermarket amplifiers and subwoofers. In this article, we will guide you through the process of installing a line out converter using a Metra wiring diagram.
What is a Line Out Converter (LOC)?
A line out converter is a device that transforms the high-level speaker output signals from your car’s factory radio or amplifier into low-level signals that are compatible with aftermarket amplifiers and subwoofers. It is also known as a High to Low Level Converter or an Audio Line Driver.
The LOC is an essential component for those who are looking to improve their car audio setup without having to upgrade the entire system. It allows you to connect an aftermarket amplifier and subwoofer to your car’s factory audio system, thereby greatly enhancing the sound quality.
