If I remember right, I only used a wrentch. I forget what socket, though. It's not THAT hard, if I remember right, this is what you do...
1. Fold down seats, undo bolts holding plastic plastic peice in place. Remove said peice.
2. Remove the cover for the rear speakers, this is the part that's a pain
3. Undo the bolts from the top, top peice should fall.
I'd put something under that large black plastic peice, though, as when mine fell, the wires snapped. Not a major problem, fixable, but still not pretty. IF you want to remove the speakers from that peice, you need a hex screw-driver.
