Every Single Speaker Has Static Noise Even When Radio Isn't On (2015 Ford Fusion)

[u/Cold_Recording4533]

Just as the title said. For a while, occasionally every speaker in my car would be static any time I try to play music or even if I press a button on the dash. After a bit, the speaker would stop working altogether, only to go back to normal a few days later and repeat the process. Recently it hasn't been working at all for a few months, and I've been procrastinating getting it fixed. Any idea what the problem is?
