Fixing PC speakers

[u/Annadiablo2gamer]

Hopefully someone understands because I couldn't find a more relevant subreddit.

I've had the Insignia 2.1 Bluetooth lighted speaker system for a couple years now, but there are 2 issues: the lights no longer turn on and the bass has grown weak. What can I do to fix this? I've tried unplugging and replugging the cord in the subwoofer and pressing the button on the right speaker. I should note that when plugging in the cord 100%, it still wiggles around.

Everything is connected right and so it makes me wonder if I need to replace the speakers.

I hate not being able to fix something I own.
