yes, you can take the cd player out if u decide to sell it, but usually by that time, the cd player has devalued so that you dont want it anymore, or its a plus for thr buyer, either way you probably wont want the cd player (unless its pricey)

and about the 50x4/60x4 or whatever your reading, it doesn't really matter, in the end they'll all sound the same
