Volvo vnl amp fuse location

Hey , my stereo won’t work. I get a message that says “ check amp fuse”
Does anyone knows where is the amplifier fuse located.
I checked all the fuses in the main fuse box.( top dashboard) and they are all working.
Thanks !

Some of the newer Freightliner have a fuse in the back of the radio.

 

Back of radio or at the amp itself possibly. Amp is up in the top right cubby above the passenger seat.

 

My guess was gonna be in the amp itself.

 

Usually radio if F ed need to replace amp fuse doesn't mean #### i've tried replacing all of them at the end of the day replace radio.

 

Also works on this truck when the ignition is not on
