popping

The title says it all really. My speakers have recently started popping, very frequently but still randomly, whenever I turn them on. This occurs even if I play no music, or do anything. I've reset the cabling, and they still do it, and i've also noted that it seems to be my front ones...

can someone give me a tutorial or whateva that lets me know how to edit everything over a model and how to make it work and everything
