I don't know what fit perfectly means but I will assume that you want it to look like it was built into the car or part of the car. For this the best thing to do is to make your own box and add fiber glass to it then cover it in vinyl that will match your car. There are some pictures in the gallery of people who have done this. If you can't do it yourself go to you closest car audio installer and see if they can make one for you.
