What is a Line Output Converter (LOC)?

A Line Output Converter (LOC) is an essential car audio device that converts high-level speaker outputs from a factory radio or amplifier into low-level RCA signals that aftermarket amplifiers can use.

Why Do You Need a Line Output Converter?

Most factory head units do not have dedicated RCA preamp outputs. A LOC bridges the gap by stepping down high-voltage speaker signals (typically 2–20 volts) into clean low-level signals (0.5V–5V) suitable for amplifiers.

Types of Line Output Converters

Type Power Source Advantages Disadvantages Best For
Passive LOC No power needed Simple, inexpensive, reliable Lower output, potential bass loss Basic systems
Active LOC Requires +12V power Higher output, cleaner signal, adjustable gain More expensive High-performance systems

Key Features

  • High-level speaker wire inputs
  • Low-level RCA outputs (2 or 4 channels)
  • Gain control for output level adjustment
  • Ground isolation to reduce noise
  • Remote turn-on output with signal sense
  • Vehicle-specific T-harnesses (plug & play)

Common Applications

  • Adding aftermarket subwoofers and amplifiers
  • Upgrading factory speakers with external amplification
  • Integrating DSP processors
  • Creating hybrid factory + aftermarket audio systems

Pro Tip: For vehicles with multiple amplifiers, an SPDT relay is often recommended for proper remote turn-on functionality.
