Sorry, if you read this before I edited it, I screwed up, the bottom 2 would also be in parallel as there are only 2

You've got 2 for the tweeter (+, - )
Then the top 2 OB woofers are in parallel so, you could just run the single + and single - from the c/o to the lower of the top 2 woofers then jumper up to the top driver (- to- ,+ to +)
You can wire the 2 bottom ones the same way, it will save you some wire. If you think you have enough, you can do it the way you originally said runnin 2 wires from each hole in the board aside from the tweeter circuit which would of course be a single + and a single -
