So we took a trip to CA this weekend and we listened to a lot of streaming music on the way. On a few (maybe 3 of the 200 + we lialiste to, there was a sound from the dash speakers that sounded like static or crackling. Change the song and it would go away. Is the speaker bad already? I've never turned it past approx half way, and bass has been kept at the middle 0 setting. Any idea what this is? The best way to describe it is static but maybe even crackling..
