how much power for tweeter

[ToyTundra 10+ year member]

i'm slowly putting together my DIY comp set. It seems like the tweeters would need less power than a mid. Am i right? My mids will be dynaudio mw160 and the tweets will be infinity for a while until i pick another. My mids will be getting around 120Wrms so i'm thinking 50 will be enough for the tweeters. Or sould i just get one huge 4 channel amp with 75+ Wrms to each channel?

Your going to want to try to power it with close to it's recomended RMS power rating.

My tweeters are getting 50 watts while my mids are getting 100. So I see no problem sending the tweet less power. But try to get close to the RMS.
