Could you elaborate/
Glenmore said:What I would do would be use a paddle bit on your drill and just cut with a hand saw to your hole. I wouldn't go to deep just enough to get the wire just below the plywood. Espically if that's the only support that you have for the floor don't want to weaken it to much. Even after you make a notch I would beef it up a little with ply wood for around the notch just to keep the strength of the floor.

I don't think notching a 2x4 to run the wires is a good idea.
First after they are notched you are going to loose where they are located and when you nail/screw down the flooring you might hit one.
Second you are adding flooring... at how much weight?? then I'm guessing you want to store things, at how much weight.... now you are going to be up there to drop things off and add more. Even without notches you are putting a lot of load and even if it doesn't crash down how much flexing will you be getting. Without to much effort my guess is that you need at least 2x6's... ever see even a deck made with 2 x 4's?
OK if you still want to do it then maybe adding a 1x2 strip along the tops with an opening at the wires and then a metal plate over the openings might be the way to go.
That's my 2 cents,
