    Hello. This problem has been happening for awhile. When i play games or watch movies, after a while my subwoofer 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.

    Usually that is a sign you are asking for more bass than it can actually produce...
    But, if it is EMI causing the problem...replace with a shielded cable.
    Shielded subwoofer is the same as digital coax and composite video(the old yellow cable from the days of VCR). So, do you have a really long yellow cable laying around not being used?
    If not...

    How do you tell if it is a shielded cable?

    Easy...
    RG6 is obvious.
    RG6(comcast/Time Warner/Dish Network/Directv)=composite video=digital coax=shielded subwoofer.
    So, find a composite video cable laying around the house and compare it to the RCA you are using now.

    If you have a spare piece of coax(RG6) laying around from when your cable/sat was installed...buy a couple of these...

    I am trying a pair of component cables I had. they are shielded. I am hoping that is the problem.

    Well, so far so good. But I am not happy until a few days goes by without incident. But thank you. The whole shielded versus unshielded thing never occurred to me.

    ugh..it started doing it after a couple of hours where it worked fine. None of the settings on it are at max. Could it still be over worked even if that's the case?

    Perfect excuse to pick up one of these...

    or (and yes the Kevlar driver is worth the expense)

    The F12 is probably equal. The VK12 would up the ante.
