That’s what I would do... 4 ohm to the low/bass connectors and 8 ohm to the mid/hi. I believe the III’s dip down to near 2.6 ohm at 103 hz. So from what I gather,they are more of a nominal 3 ohm load. More current into lows connected that way. Of course,nothing is written in stone...
Also... When I was using a single run of cable to the III's I connected the cables to the low connectors and jumped to the mid/highs. This way seemed to let the speakers give a much more musical presentation overall. The other way around thinned the sound out a bit,at least with my system. ymmv
