Most amps can handle a 4Ω load. It will develop more power at a lower drive voltage, so it may run out of current capacity with the volume knob at a lower setting. If this happens, it may sound distorted or even kick in a protection circuit. Just don't turn it up to the point of distortion and I think you'll be fine.
