A line output converter (LOC) is a crucial component when upgrading a car’s audio system, especially when you want to keep the factory radio. The primary function of a LOC is to convert the high-level speaker output from the factory head unit into a low-level RCA signal that aftermarket amplifiers can use. This is essential because most aftermarket amplifiers are designed to work with low-level inputs, and directly connecting them to the factory speaker wires can damage both the amplifier and the head unit. A properly wired LOC ensures a clean and clear audio signal, allowing your new amplifier to perform optimally and provide the enhanced sound quality you’re seeking.
