I told my dealer that when I unplug my amp the noise will stop so they order me another amp but like you said it's on backorder. If you like myself I have the alfabod I went and using the alfaobd "NOT ENABLE" the ANC feature for now but I haven't drove it since I change it.They all have it. When the thumping starts roll your window down. It will stop when the window gets to about half way. Roll it back up and it will start again.
It’s the ANC system gone whack. You need to take it to a dealer. Have them verify and then they will order a new amp for you. Which is currently on backorder.
If you can’t stand the thumping then there are posts on here about how to disconnect the ANC mics which essentially turns off the ANC system and stops the thumping.
