Rear surround sound speakers cutting out
I have a Vizio 5:1 soundbar and surround sound for my living room TV (Model M51a-H6).
My rear surround speakers will cut out and then stop working completely--they are hard wired into a wireless subwoofer.
The system is about 5 years old, so out of warranty.
I am able to reset the speakers to get them working again, and then the moment the sound gets a little loud, they cut out (both of them)--and I cannot get them to stay working no matter how many times I reset them.
Is this an issue with the speakers, the woofer, or the whole soundbar system?
I was hoping to be able to just buy different but compatible rear speakers and wire them to the connectors to the woofer, then I read the issue may be an issue with something in the woofer itself.
Can I buy a replacement woofer to fix the issue, or are there any other options?
