Not to hijack Loren's thread, but Jim Hogan (who I think was the first WRX owner to do an empeg install) suggested to me that I tape off the area with masking tape then "score" the paint and plastic with a razor blade to make a clean line. Then use a dremel (not too fast of it'll melt). I guess the masking tape and scoreing helps cuz it worked for me!

Way to go Loren! I would have put a pocket but I only had a "CDless one" and it wouldn't fit for the life of me.
