Can I run 4 ohm speakers with my Pioneer SX-650

Any help appreciated. I just got a Pioneer SX-650. My bedroom and bathroom are wired for speakers with a panel in family room. At the panel I got just over 4 ohms so I assume all the house speakers are 4 ohms. I want to run two bedroom speakers off of the two "A" speaker outputs. The bathroom has a single speaker. I am thinking of bridging that using the two "B" speaker outputs. I take that to mean I connect both sets of outputs to the lone speaker (not sure if I reverse polarity or not).

Questions:
1) Can someone confirm the problem of running all 4 ohm speakers is overloading the amp and possible damage?
2) The unit specifically says 8 ohm minimum if running all 4 speakers A+B. Does bridging B make this concern somehow disappear?

3) If I just don't run the volume up can I wire the 4 ohm speakers and not worry about it?

Thoughts appreciated,
Robert
