Wow, thanks for answering !
By the way, I managed to have a look behind the steering wheel. I've found 2 rubber grommets but when trying to pierce both ofthem with kind of a needle, the tool is blocked shortly after. As if there is no way to pass through without drilling.
Did you drill through ? Maybe my car model is a bit different?
Regards.

Re: C5 X7 amplifier power cables, trunk ground point
Can you pry out the grommets and see what is behind them?

Acces is realy difficult. I'have done this for the lower one.I saw grey foam (thin) and behind something hard to the touch (with a big needle)

Re: C5 X7 amplifier power cables, trunk ground point
My car is Left-hand-drive, 2.0 petrol.
Take a look: the cable I'm holding with my thumb is the one leading to the amplifier, you can see how it enters the firewall grommet.
I also took pics of how I installed the fuse, maybe this brings any value to you (in the ECU compartment, I've removed battery cover and the ECU cover to take the pics)
I don't remember if I had to drill, I think the grommet is quite thick so its not really possible to pierce it with a needle, maybe try removing it with pliers first to take a look.

Hi, after checking my model doesn't have this gromet. (Hdi160 exclusive).
Anyway I managed to pass my cable using the method used in this video :
Maybe this info might help someone.
Many thanks to everyone answering to my messages !
