car radio power supply

Hope this is the right place for this question.

I've been looking for a compact radio for our kitchen, that will play CDs 
and MP3 disks, as well as a line-in plug.   There aren't a lot of radios
out 
there which fill the bill, except for auto radios -- lots of features and 
very small, could be mounted under a cabinet.     What I can't find is
what 
sort of power supply would drive a car radio  in my house.  can anyone
help?
