What size/kind of solar panel would i need to keep a car battery charging?

Question

I'm looking to run a small stereo off of a standard car battery on a trip i will be taking next week, and was curious what kind of solar panel i could use.

I figure i wont be able to just use of the 'top-off' solar panels for cars, but i'll probably need one that's meant for charging batteries from a semi to severely depleted state.

Any suggestions?
