I was sitting at my computer yesterday and i was just searching the web and i kept hearing this popping noise and i thought it was my speakers, but it didnt come from them then i went below to check the sub and random bass pops kept coming out of them. I checked the subwoofer setting and it was all the way up. I turned it down and didnt hear nething. I cant really tell if it is making this sound when im playing music or something because i cant determine if they are coming out with the amount of bass coming from the music. What up with this can someone tell me what is happening?
