Help, I think my sub might be dead.
Couple of days ago, I started hearing "knocking" thumping from my sub even when my amp was off. I turned off the sub thinking it was maybe some interference from somewhere.
Now, when I turned the sub back on, all I'm hearing is a hum from the it and nothing else even when music or a movie is playing.
The sub is a EP175, less then 1 year old.
Definitely call Axiom. Those symptoms sound a lot like a defective amp on the sub or one about to fail. Leave the subwoofer turned off and unpluged in the meantime.
