I have a M&K V 125 sub. A few nights ago I noticed a loud humming. I adjusted the levels, no change in hum. I disconnected the sub, no change. I moved it to several different ac outlets, still hummed.
After reconnecting it and deciding I could live with it for a while by unplugging when not in use, I noticed it started sounding like it was "thumping" at high levels. Not sure how to describe this other than the sound I hear at redlights when someone is playing loud hip hop and it sounds like the trunk of the car is coming apart.
Does it sound like the sub is blown?
Should I try replacing the driver?
Any help would be appreciated.
