Wrench light after car stereo installation

[tarnisil]

I installed an amplifier and a subwoofer on my 2015 EB. After that, the orange wrench light appeared. A DTC error is present saying there is a problem about electric signals transmission.
Ford's techs were not able to turn off the light.
Has anyone experienced a similar problem with the installation of an amplifier?
The carstereo guy said he did as usual, by connecting the positive close to the battery...
Any help will be greatly appreciated!!

Well because everything is tied together to each other

if he hooked to the wrong post at the dist block... it would have popped one of the main fuses.... check where the main power wire is hooked to.. Mine is hooked to the same lug that is fed from the battery.
