As per RonRizz, most amps will handle an impedance mismatch reasonably well. There will be some added distortion but, if you don't push the amp hard, it shouldn't be a problem except for with the worst-designed units. However, if pushed hard into a low impedance, it will sound bad and can cause damage to the amp and speakers. Try to match impedance as closely as possible, but a small mismatch is not the end of the world.

Keep in mind that driver/speaker impedance is given as a nominal value and will, at resonance, be lower than the spec. A 2 Ohm speaker may have 1 Ohm impedance at resonance.

Edit: Oops. Impedance is at it's max at resonance. It's at the frequencies above and below resonance that impedance drops.
