GMC Envoy Speaker not working?

[Ariel G]

I just found out that my rear door panel speaker isn't producing any music sound/music. It was checked and found that the speaker itself is fine, but it is not getting a signal. All wires are connected alsom btw. Also, all the other speakers work fine and the stereo head unit works just fine.

What could be wrong with this speaker not getting it's signal?

Thanks in advance
