So one day for no reason I woke up and there was no sound in my car

I tried everything and as follows

Checked the fuses ( good )
Change the amplifier
Changed the satalite tuner
Changed the Bluetooth module
Also tried to by pass them same thing

All rear fiber connections are running ( red light )

When going to ista it says no communication with ( amplifier) and ( no communication with satellite tuner ) the car thinks that it's not plugged in


Any help ? I spent so much money trying

Was there any water built up by the amp? I had the same issue and the amp was still lighting up and the fiber optics were still working but was not putting out noise.
