I seriously doubt any damage has been done. As far as I know, even if you're just running one set of the drivers, they're still a 4 ohm load.

Think about it this way: if you were bi-amping, that one set of drivers would be presenting the same load to one of the amps. The speaker has no way of knowing you have 2 amps hooked up.
