Speakers

Sorry I don't know the proper term but it's the deafening sound just like you point the microphone toward the speakers.

Anyway, my 4ohms speakers have this problem when I karaoke with the volume fairly loud. When I switch to 8ohms speakers the problem went away.

Could someone explain why and if any damages done to the speakers or receiver/amp when it happens?

Its called feedback. If everything is playing okay, surely you are in the clear. Except for maybe your ears :), any damage is going to be acute.

But why would it happened for the 4-ohm but not 8-ohm speakers at the same volume?

Just a guess, but it might be the pattern your speakers broadcast rather than their resistance that's making the differance. I work with some proaudio and have seen all tweeters blown at the same time, it only took a second. Try aiming your speakers such that the mic is always behind them.
