Why is my Lightning Audio Car Amplifier not turning on?
- Jjennifer31Aug 1, 2025
If your Lightning Audio Car Amplifier isn't turning on, it might be due to insufficient voltage. The B+ or REM voltage may not be between 10.5 and 15.5 volts, or there might be no voltage present at all. Inspect the alternator, battery, fuse, and wiring, and repair them if needed.
