Cool, thanks guys. I think my battery died over night because yesterday I tried turning on the stereo and nothing... had no power to anything. I would say that I played about 4 hours worth of music on it but most of that time was 30 degree weather over the winter. Now, I have no idea how charged the battery was when I bought the boat and I'm hoping it just wasn't fully charged. Weird thing is that when I played the stereo the other night it seemed fine but then the next day I went to turn it on and it was completely dead.. I would think there would be signs of it dying. hmm..
