No, I don't think they're a 2 ohm load; if they're on different amps, they're on different amps, and they're a 4 ohm load each.
I think the real question here is, "Why do you need 2 M80s per channel?!" WHY NOT! lolololololololololololololol Actually, the layout of my house is open. So much so that the opposing wall from the M80s is 60ft away. There is furniture, a partial wall and a pool table between but that is it. Sounds great under the pool table but I can't really get into the groove from there! So the second set is there to help fill the room with sound. I was also considering adding another system on the opposing wall and wiring them together to work in unison. That way BEER CAN CRUSHING POWER can be had from anywhere in the room! My only worry was being able to sync the sound from 2 different amps (even if the same make and model) when they are 60ft apart.

I would have certainly hoped it would have just gone into protect mode and shutdown till it cooled off, but that doesn't sound to be the case. Apparently, Denon's idea of "protect mode" is to let the $2500 amp blow to save the $5 fuse?

So it blew with a 4 ohm load. You must have really had it cranked up for awhile. Did you check the fuse yourself or just take it back in due to warranty concerns?

Actually, I have a question, peenerhead. In your initial post, you mention "jamming". Are you connecting electric musical instruments to a domestic amp?

hmm.. I thought the amp assign feature was for connecting two sets of speaker cables to the same speakers.... You are correct but there are other options. I assume it's not too different from my 3806 where the extra amp can be assigned to duty for -- "Surround Back" for use as rears in 71. -- "Front" used for bi-amping. -- "Front B" used for a constant second stereo channel (duplicates fronts) -- "Zone 2/3" used for fronts in another room that can be turned on/off independently. I believe what he is describing is that he has his second set of M80s hooked to this extra amp and has the Amp Assign set to "Front B" or the equivalent. If this is correct, it is indeed only a 4 ohm load being presented to each amp.

The problem is that it is still only one power supply feeding all the amps and 2 amps with a 4 ohm load, while being played at high volume may have fried the P/S.

I think Jason may have the right of it there.
Anyway, in answer to your original question, the binding posts are split like that (1->woofers, 1->midranges and tweeters) for biamping and biwiring, two dubious audio practices.

Edit: In response to the single power supply being a weakness in this configuration... (a few posts popped in while I typed.)
Agreed. I was just trying to help sort out the wiring questions. Good call on checking the fuse too. I know I would go through a short period of mental anguish before settling my brain down enough to pop the cover to check the fuse and look for toasted components.
