Why is the Protect-LED lighting up on my Renegade Car Amplifier?
- Ssabrina82Aug 12, 2025
If the Protect-LED on your Renegade Car Amplifier lights up, the amplifier has entered diagnostic mode. To diagnose the issue, disconnect all RCA and speaker leads, leaving the +12 volt, power ground, and remote leads connected. Turn the amplifier back on. If the Protect-LED lights up again, the amplifier has an internal fault. If it doesn't light up, reconnect the RCA cables and reset the amplifier. If it then goes into diagnostic mode, the problem is with the input, possibly due to bad cables or the source unit. If the amplifier works with RCA cables connected, connect the speakers one at a time. A faulty speaker or its wiring will activate the protection system.
