Focal Inside - IS BMW 100L installation - BMW 5 Series 

Where do you ground the crossover??

What material do you use to block the holes that need to be drilled? It is not included in the kit.

Va bene per una bmw x1 e84 del 2010 si monta come nel modo del tutorial grazie

Are there any written instructions for installing this kit? I am trying to work out from this video where the ground wire for the crossover should go and how the tweeter connectors should be attached it's just too hard to see from this.
