    This is my vote as well. Lower impedance means that amp can deliver more power to the speaker(s), but really it's only going to deliver as much power as you ask it to. At everyday listening levels it'll be fine. If/when you crank it up, keep an eye on the amp's temperature, turn it down if it gets hot, and keep it under that level in the future.

    If its an old school RF amp it probably won't have any problem running the 3 ohm load.
