Hello. This problem has been happening for awhile. When i play games or watch movies, after a while my sub woofer starts to make popping sounds and other little noises. When it does the popping, the light blinks between Red and Green. I have it hooked up to my receiver via a RCA cable I had laying around. Is it because I am using those cables? I am looking for a direction to start going into to resolve this . Thank you.
