No Sound

Removed the amplifier that was certainly blown, and replaced with a replacement purchased on ebay. I now see the replacement has some red leds that light up, BSD fuse is still good, but still no audio. I thought I must have gotten a bad replacement amplifier since i ordered it on ebay and purchased a 2nd replacement amplifier and still get the same problem, no audio. Double checked the BSD fuse and its still good. Checked all of the fuses in the trunk fuse box and they are all good. None of the fuses under the passenger side dash appear to be relevant so I didn't check them. There are some additional fuses listed for the 200 and 300 number fuses that appear to be relevant but I can not find the fuse box for. I will post a picture of the fuses boxes I can't find. Any help before i take this into a service shop for professional help?

Have you checked for power at the amplifier harness?
Do you have ista? It will show you the wiring diagram and you can check voltage.

Do you have an install behind your nbt ? Check the optical cord is plugged well.

I would walk through the whole MOST sequence again. If somehow your amplifier was blown when you reinstalled the BSD then maybe something else got impacted. Maybe your bluetooth module is bad? Sorry to hear though that you are suffering through this...it was painful to be without sound for over 7 months and wished I had just sucked it up and took it to the dealership sooner but the only good thing is that because I did my own troubleshooting, I knew what to remove in their "recommendations" which included replacing the amplifier because he "saw" it had water impact.

So my 2015 was exposed to some heavy rains today. Long story short water got on the front right carpet and underneath. I lifted the carpet and dried it as soon as I could. But while I was driving with the water on the carpet the speakers we're making crazy sounds and eventually stopped. What do I look for now? Possible fuse blown? Can anyone assist me please.

Sounds like sunroof drains are plugged.
Plus you probably have more water under the carpet. And water probably got on wiring harness. Probably need to lift the carpet in more places.

They were and I think I cleared them out. I ran water down the sunroof later and confirmed it was coming out the bottom. I did some testing and the 50 amp fuse above the battery is in fact bad. That whole assembly has to be replaced correct? It's what it looks like

Ouch. What is that fuse for?
The amp is behind the left side panel in the trunk area. Maybe it got fried?

Per a previous post I found it's for the audio amplifier. I hope this will be my fix.
