I have an RCA RS 2663 Audio system, and when I play a song through my speakers they have a skight popping noise, but when im on skype and my friend plays music through his speakers they don't pop, even though I can still feel the bass coming through my speakers from his krk's. Any advice on how to fix them or should I just get a new audio system? I'm planning on getting a new audio system for my birthday, but I would like to avoid it as long as possible because I don't know if ill have enough money.
