Amy, I think one of my SWS sub might have a bad input or something. It makes popping sounds randomly. Sometimes when I move the control pod, it does it too. I don't want to go without the SWS because there's no way I could get this quality of a sub for the price I paid. I'd keep it if you guys can't fix it, because it's a small price to pay for such a great lil sub. But if you guys do have a new replacements, do you think it would be possible for me to get my hands on one?
