Speaker wiring help

I am salvaging some parts from a pair of these edifier bookshelf speakers and also a few parts I have which are two of these woofers and two of these tweeters . I was wondering what the best configuration would be given these parts (2-4 Ohm tweeters, 2 - 4 Ohm woofers, 2 - 8 Ohm tweeters, and 2 - 8ohm woofers)?

Should I make one enclosure full of 4ohm parts and one of 8ohm parts? Is there a crossover I can buy pre-made that can help with this? Should I wire them in parallel or series?
 
Hmm. Some speakers do have two woofers. They can be one 8 ohm and one 4 ohm but it's unusual and a little tricky. Maybe you can see if the specs for the ones you want work by themselves in the volume of the box.. or consider getting another couple of the same type if they fit the box volume in pairs?

The data sheets will help here.
