Actually, you can't really "overkill" so the large wire for the woofer is fine, but you don't really need to go bigger than 16 guage for this coil, even if it has an air coil. The required coil in the tweeter circuit is a bit surprising, because there actually is the potential for a reasonably high current through this coil. But 20 guage is fine there.
