From what I understand, bridged power is never good as unbridged for two reasons: 1. possible noise is introduced in bridging and 2. Current capacity is halved when bridged.
Current is extremely important in controlling large low ohm drivers.
I would look at running them unbridged or go with a different amp. I personally have HK 5800 5ch amp and this thing is great with great HK sound. Although its only 80W/ch Runs my 4 ohm speakers well, almost well as my 200w/ch Rotel. With the extra channels, you can try passive biamping....Good luck.
