THey are 4" holes but on the drivers side there's about .5" mounting depth. They didn't use those holes because they ended up with too much shit behind them on the driver's side.
And take your tweeters out of the dash and mount them in your doors between the door handle and the air vent. In the dash is the worst place to have them in our cars.

Guess I didn't answer ALL of your questions. No, there are no wires there. And I hope you're not thinking about running 8 speakers off your head unit cuz that's fry city right there for your head unit.
Most "8 speaker systems" involve a mid/tweet combo up front, pair of 6x9's in the rear, and a couple of small crappy subs
