Why is my JBL Spyro Subwoofer not turning on?
- MMatthew TaylorAug 12, 2025
If your JBL Spyro Subwoofer isn't powering on and the green LED is off, check that the wall adapter is properly plugged into the subwoofer and a working outlet. Test the outlet with another device like a lamp to ensure it's providing power. To isolate the issue, connect the JBL Spyro to a known audio source and test the audio source with headphones.
