sub just started doing this: thub when receiver is turned off or muted (1 Viewer)

[brian stiles]

does it also when changing the radio stations. ...now. .maybe something is crossed or whatever.. but to my knowledge nothing has been moved.. ...if it doesnt hurt anything i dont really care that much. ...kinda warns the guests the presence of a sub!. .the sub is a m&k v125!

thanks for anything!

Brian,

Maybe you (or anyone else) moved (even slightly) the sub recently, say to vacuum, or dust behind it? Are you using a shielded cable? If so, and the problem just started (not a new setup), then it sounds like your shielding (ground) may not be making a good connection. Check the cable at both ends to make sure they are completely plugged in. Also try another cable from output to the sub.
