Will these work on 4 inch speakers?

Yes, these bass blockers can be used to protect your 4" speakers as well. The BB-35 blocks frequency under 2800Hz for 4Ohm speaker, The BB-4 blocks frequency under 1200Hz for 4Ohm speaker.

How muh does it block on 1 ohm ?

Following quick and dirty math, the frequency doubles at 2 ohm (0-600 hz). That would make 1 ohm frequency blocking 0-1200 hz.

Will these fit in the upper dash of a Wrangler JL for the tweeters?

Yes, these bass blockers are super small and compact, they should fit into the upper dash of Wrangler.

I have 4 ohms tweeters, how will it sound with these 4 ohms blockers?

All it will do is drop off the lower frequencies (which tweeters can't play anyway). Your highs will play through perfectly.
