While it's not likely to get a shock from a sub, if it was grounded, I would try and keep it that way. The ground loop is most likely from cable TV. Unscrew it and see. Find a way to break the ground there. Jensen Transformers is a good solution.https://www.jensen-transformers.com/home-theater/video/
How to remove ground pin on power cable
This is a power cable being used for my subwoofer. I have a ground loop currently. According to the manufacturer of my subwoofer, due to it's design, it is perfectly safe to remove the ground. Right now I do so with a cheater plug but I would like to avoid having to use it. The power cable in question is Oyaide Black Mamba V2
How easy is it to take a power cable apart and disconnect the ground? Is it best to do so at the IEC side or the pronged side? What is the process for doing this?
Thanks
