What is making it have a crackling noise? Can it be easily repaired?

I accidentally ran over my JBL charge 3 when I stupidly left it on the top of my car when I was in a hurry, cosmetically it's fine , still plays music & charges but it's making a kind of crackling noise within the speaker. I don't believe it to be the 2 side speakers I think it's one of the enternal speakers. Only does it when the bass really hits…can I fix it myself? Or is it just permanently ruined?
