I don't believe anyone was running their amp bridged while powering the M80s, that's just their excuse for their amp shutting down. I don't know of any amp manufacture that will say to run any speaker below 8 ohm in bridged mode. While doing so the lower impedance speakers would draw far to much current and shut down.
