So I was driving one day and I turned on some old 70's 80's music from the country, nothing bass crazy or anything just chill songs. Then every sudden beat drop or loud noise in a song the rear speaker makes a violent noise almost like im hitting a pothole and shit goes flyin around back there. But it's consistent too and doesnt stop. Tried different music, tried crankin it all the way up because really im out of options. I dont believe the rear speaker is blown, but i'm just wondering if anyone has had this issue before. Below is a link to a YouTube video of my speaker issue...

P.S. This is just the local station and I did not choose the song so don't say anything about the music choice....
