My wife bought me this setup for Christmas via Walmart.com, and recently the subwoofer has been making a popping and crackling noise mainly when it comes to anything bass. I have checked all connections to ensure they are secure, and have adjusted the bass, treble, etc settings to try to fix the issue to no avail. What can I do now?
I’m sorry you are experiencing these symptoms. Make sure that the unit is not close to the wall. Make sure there aren't any heating or air conditioning
vents pointing directly at the subwoofer. Verify that the subwoofer is on a flat and level surface. Tilting or an uneven stand can increase these noises. Can you try the troubleshooting steps provided in the link below:
