I have a dynamo 500 that is only about 8 months old. Over the weekend a friend came over and turned my system up well beyond where I normally ever play it. I quickly ran into the room and turned it down, but it played at a very high level for about 20 to 30 seconds. When I say it was being played at a high level I mean it sounded way over driven. It sounded absolutely terrible and like the speaker was blown. Since that event my sub has been randomly popping while playing and also when my entire system is turned off. The dynamo has the auto on/off. When it makes noise with the receiver off it will make a fast much softer popping noise that accelerates and then stop after a second or two. When it makes the popping noise while the receiver is on it usually occurs around areas of low bass. What could be wrong with my sub? What do I need to do to figure out exactly what is going on with it? Any help is appreciated.
