what guage wire for tweets?

[slow240sx]

I got 4 selenium mids. Gonna run front stage active. Got a old school pg zx350 to run a set of tweets. It rated 75x2 but should do a good 125x2. Gonna use my jl tweets for a few weeks till I figure out what tweets to buy. I got 18 guage in there now but I was using less power before. Should I use 14 or 16 guage to handle the extra power or do tweeter wires not need to be big? Prolly end up using a bullet tweeter of some type cause I don't want to cut out a big hole in my door.
