I have subwoofer instead original net on the right side of my car, but I have wanted it. I asked Citroen, but they said, that could not be order only net . Therefore I have made own net from wire and some net from my previous car according to picture of original net from web .
had a similar problem with Citroen Servis in the case of move my legs blue light
from my previous Honda Civic to my DS4, because mainly my wife wanted it in our new car as well. I had to remove the lights alone and connect it to
lighter (because of warranty) with install one manualy switch for change the
dark and day mode of lighting. But effect mainly during night ride is very cool
and was worth the effort. Do you have somebody similar lights and how you connected its to car's electric net?
