I was so foolish. I accidentally unplugged the stereo (3.5mm) jack of off my sound card with the speaker on. The volume and bass both on 1 o'clock. The sound came "krrrrr" so loudly. They still turn on after that incident. But I'm worrying about the amp. Would that do any damage to the sound and or the component?

Thanks in advance
And sorry for my bad english

Hard to say... Most of the time a short burst will do no damage.
Also keep in mind that every incedent is unique with the same results.

You could try listening with some material that has lots of dynamics and space to
determine if there are any weaknesses against the frequency spectrum at a
normal level.

You could also try a freqency sweep with a tone generator (hardware or software).
