Hi guys! I had this subwoofer for 4 days and yesterday when i played playstation, i heard a weird crackle and pop from the subwoofer. After that, it stopped working. There was a green light on it, but no sound. I removed the powercord for 5 minutes, and now, everytime i plug in the power this happens. https://www.youtube.com/watch?v=983QxAEIF3w Everytime, the element gets sucked in and the green light lights up whenever it does it. And it does this 3.4 times until it shuts completely off. No green light anymore until i remove the powercord and plug it in again. Any idea what causes this? Should i just deliver it back and get a new one?
