Pro amps from Crown, QSC, Behringer, Yamaha etc will be stable with low impedance speakers and you will also have an abundance of power at your disposal as well.

But before you get a new amp, do make sure there is no short in the chain somewhere - either the speaker or cabling because if there is your next amp will have similar fate and try to protect itself and shut down if it senses a short.
