Alright. New noises happening. I usually drive with my music on. Not loud or anything, just something in the background. This week on my way to school, when I've been sitting at idle in drive, I hear a popping sound come from what seems like the right rear. When I mute the music, I hear nothing, so I'm assuming it's something with the stereo. It's not even bassy music when this happens. It's just really random.

I'm really funny about noises and this sounds really meticulous, but it still kind of drives me crazy. Any suggestions?
