I have a subwoofer in which there is a strange noise with the speaker
as if the voice coil or the cone of the speaker is touching somewhere
so wat to do to prevent the noise . . .


Check whether the gluing of the cone periphery or the skirt has failed.
If they are sound
At low power level try pushing the cone in a radial sense in diferent clock
positions and also the same with the skirt/spider.
