Magnepan MMG & McCormack Amps questions


I have a pair magnepan MMG's powered by ONE McCormack Micro Line power amp. Pretty stupid. So, I bought another Micro amp and was thinking of bridging the amps to mono and using them as mono blocks.

Now that I have already bought the second amp I am now wondering if this is a good idea. My typical measure once - cut eighteen times job.

Any ideas? Advice?
can the amps handle a 4 ohm load when bridged? Some amps cant bridge below an 8 ohm load.
That's what I'm wondering. I don't to destroy my speakers.
I would call Steve McCormack for a definitive answer.
