The easiest way for me to get access to the space behind my bathroom vanity to
run some electrical wiring will be to cut a big hole in the sheetrock. It seems
that if I cut the vertical lines down the center line of the 2 x 4 studs on each
side, the panel will be much easier to reinstall. It's a no-brainer to cut a
hole in sheetrock with a sheetrock saw, but how can I cut just the 5/8" or so of
sheetrock that is against a stud?

A circular saw would work, but the sheetrock would probably destroy the blade. A
MultiMax tool might be a good idea, but I don't have one. The ideal solution in
my mind is a Rotozip, but I don't have one of those, either. While I do have a
router, it's quite large and would be hard to handle on a wall like that.

How you you professionals do this, or is there a better way?

I'm not a professional, but I've done this with a normal utility knife
-- just start scoring deeper and deeper until you get through the
depth of the drywall. If I had dozens of these to cut, I'd get a
rotozip, but one or two will only take 5 minutes to do by hand.
