2011 Outback, 2.5 with factory audio.

It looks like I've got a leaky sunroof, or more precisely a sunroof that isn't draining properly. After a hard rain the rear carpets were sopping wet. I think I have a handle on what I need to do to get the drain tubes opened up again, but now I'm not getting any sound from the audio system, even though the dashboard unit is alive and lighting up, and everything is completely dry now. ChatGPT is telling me that the likely culprit is the amplifier. I haven't removed the seat to inspect it yet, but is this amplifier likely fried? Or is there an inline fuse somewhere that might have protected it? Any words of wisdom for a failed audio system after water intrusion?

You need to remove the amplifier. I dare say it’s toast. They don’t take too well to water ingress, and there will still be water in there even though your carpets are dry.
