You can get sound from an fm radio as well as speaker. You might want a portable for out side so you don't run your car battery down.

Yes you can, plus the movie theater pumps up the volume on their speakers

Yup, you can also rent a radio for $5. They also have the old ones that are on the pole that you can hang on your window.
