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.
