Gotta be nice not dealing with earphones. Reminds me of a moped we called 'The Hog' a few years ago. We put a 12 inch sub right under the seat. It was all powered by a 200 watt amp bungee corded to the seat behind you. All ran off of a car battery that was strapped to the floor board. What a wild ride that was. People could hear ya commin' like nobodies business!
edit: Here's a pic of the hog!
