How to troubleshoot Cerwin-Vega Subwoofer amplifier that will not power up?
- LLaura DavidAug 7, 2025
If your Cerwin-Vega Subwoofer amplifier won't power up, begin by ensuring a solid ground connection. Then, verify that the battery (+) terminal receives at least 12V. Next, confirm the Remote Input (Turn-On) has a minimum of 10VDC. Check if the green power LED is illuminated, and inspect all fuses, replacing them if needed. Lastly, ensure the Protection LED isn't lit. If it is, briefly turn off the amplifier and then power cycle (reset) it.
