Unlikely that anything will blow up, but the amp will struggle to provide enough current to drive both sets of speakers cleanly, at least at anything above very low volume.
That increases risk of damage to speakers.
Best solution is to get another amp, and use one amp per set of speakers, with switching on the input side.
