So i let my sister drive my car to school while hers was at the shop. And later that day i drove it to the store and my speakers sounded a little g@y. I know my sister is a huge Justin Bieber fan so i'm sure she bumped it in my car... Do you guys think it was a result of bumping Justin Bieber? I tried bumping something else like Elton John but it made no difference.. please help?
