lol... I know exactly how you feel. I have 2 JL Audio 12"w3v2's with an 800 watt kenwood amp it is almost to the point where the rattling is almost muted out. But not quite there. The license plate was the first thing i fixed, and there ae thoes 2 little black plugs under the car right about where the spare tire is. One of thoes rattle like hell. So some silicone will do the trick. As for the third brake light is concerned, i have no clue on where to start or how to fix that. It almost looks like the light is hitting the rear window, and sounds like it is. Does anyone know how to strengthen/stop that from rattling. Thankx.
