I have a JBL ARC SUB 8 that I bought new approximately 8 years ago. It's been well taken care of and never abused.

It's connected to my receiver by a standard sub cable to the sub out in the receiver. The receiver its self is only a couple of years old. Its a Panasonic SA-HE100.

Some time ago, the sub started to cut out. When it did it would making a popping sound. This became quite regular.

Unfortunately, now it makes no sound because it doesn't work . I do not believe it's the receiver.

The sub powers up fine. I've checked it over but can't find anything wrong with it.

Any suggestions?

Many thanks in advance.
