We were wake boarding everything sounded fine. The song changed it was a bad quality song and sub was making a rattling sound. Before I could turn it down it quit working and hasn't worked since. It's a 10" JBL the amp is JBL as well. I noticed the amp has a orange light on the front. I don't know if its supposed to be orange or green. Maybe someone with more knowledge can help out. Does it sound like I blew it or is there a safety that shut it off?
