ohm range

Hello all, need some wiring advise for some speakers. I have four JBL 3ohm speakers and two 4ohm tweeters, I am running a amp the can run either 2ch at 4 or 2 ohm, or bridged 1ch at 4ohm only. I'm trying to navigate a way to wire all these speakers, that the ohm range will be stable. Any ideas?
