If you need to drill a 1-1/2" hole you can either use a hole saw or a step drill bit. Either of which should be available at most DIY centers or hardware stores.

Place it flat touching a wooden surface. Use nail and hammer to punch small holes making a circular array of holes. Mark the holes you require beforehand.

i agree this is the easiest way. unless you already have a dremel, which would be my first choice.

drill (as steve suggested) , dremel, i do not suggest so but exacto knives cut through aluminum also, metal files. i personally use a simple and cheap dremel if you do not have one it is a good investment but a drill could work also you just need to know what you are doing

Make a speaker grill effect by drilling with a fine drill through a piece of "perf board", which you can get from a Radio shack - mark a nice pattern on the perf board and use the 0.1" perfect spacing as the guides.

+1 to that.

I've been using the perf board method since Steve introduced me to it some time ago.  Works a treat.  I use double-sided sticky tape to hold the board down.

Not applicable in your case but if you're drilling plastic, make sure your drill bit is sharp and use a slow speed to avoid melting the plastic.
