Welcome Nigel. I would think* you'd be ok if you're not running the speakers in parallel off of the same channel (where the ohms would drop considerably) but with 4 channels. Alan Lofft wrote an article that may help you.

You may possibly require an impedence matching selector switch(not expensive at places like Parts Express)....I've never tried this, so hopefully someone with more knowledge will pipe in.
