I don't think that a 4 ohm speaker can hurt the amp if you're currently running a 2 ohm speaker. You will lose power if you switch to a 4ohm speaker.

There would be more of an issue if your system is spec'd to run a 4 ohm load and you are running 2 ohms.

Considering ohms law, the amp will deliver less power to a 4ohm impedance then it will to a 2 ohm impedance.

So the 4 ohm speaker will put less stress on your amp.
