What wattage tweeter replacement?

[Toy4R4Me]

Hey all, I have a '05 SE with the JBL system and I blew one of my tweeters in the front. I'm going to replace with 3.5'' per this thread. I am running a sony XAV64BT see here. My question is: what wattage speakers do I need that will sound good with that headunit?

I see that it has 17 watts RMS power output and 52w peak output. Running through the JBL harness and such I have no idea how much actually goes to those upper door speakers, though.

thanks in advance for the help!
