single din to double din...

Is it possible to go from a single din deck to a double din in a 95 prelude? If so, do I need to retrofit an installation kit for another car so I can do this? Thanks for any information!

A 95 prelude is already a double din. I have a 92 which is also a 4 generation and they already are double din, they come with a headunit and tape deck on top and then the slave cd player under that.
