where can i buy a cd radio player for my nissan micra 1995 model?

i bought a nissan micra and tryed to fit a cd radio player in it , once installed i had problems with the back light and dash board lights so had to take cd player out i since found out that the cd radio player might be to powerful for my nissan micra with it only being 1995 model so i want to find out where i might be able to buy a cheap cd player for my car that isn,t gonna be to powerful.
