If you are making a square opening, use a cirscular saw. In my experience you should do it with the finished exposed side facing down. This accomplishes two important things: 1) You wont have to worry about maring the eposed side. And 2)You will have a nice clean cut. Also you will have to finish cutting the corners with a jigsaw,because the circular saw's blade is round and will not cut to the corner of your intended cut. You will most likely have to round over the SHARP edges with a file or sand paper. Did I mention that the cut edges will be sharp?

As far a cutting out a round opening, you will have to use a jigsaw. Use the advice posted first and you should be fine. Anywho, good luck.

THis advice is assuming that you are pretty handy, so if you are not then maybe have someone else who has some experience do it.
