It probably started from when I got the speakers so around 4 months ago.
So, I noticed that the left cables wouldn't go in all the way to the subwoofer.... I've tried multiple times to insert them as fully as the right ones, but it never works out..Here's a picture:

I've tried multiple jacks on my computer too.
Also, on a lot of beatles songs (pretty sure in stereo) I have noticed that half the sound is missing so it makes sense that one of the channels isn't working properly.
It makes me sad, because for most songs the sound quality is great but for a non-significant portion of songs it doesn't give me the full experience
Thanks for the help btw
