The subwoofer may be humming due to a ground loop issue, where there is interference caused by multiple ground connections in the audio system. This can result in a low-frequency hum or buzz coming from the subwoofer. Additionally, the subwoofer may be picking up electromagnetic interference from nearby electronic devices or power sources, causing it to hum. It's also possible that there is a problem with the subwoofer's internal components, such as a faulty amplifier or power supply, leading to the humming sound. **

The converter is likely humming due to the electrical components inside vibrating at a frequency that produces the sound. This vibration can be caused by the flow of electricity through the converter, which creates magnetic fields that interact with the components. Additionally, the converter may be working hard to convert the incoming electrical current to the desired output, leading to increased activity and noise. Regular maintenance and ensuring proper installation can help reduce the humming noise from the converter. **
