Hi guys, I bought a Canton CS 2.16. Now I have a problem… So I connect my boxes and try to put the cables through the hose between the door and the body. I notice that it doesn’t work at all. Because there’s a plug that I just can’t get past. So is a plug that is turned like a thread in an attachment in the tube. Nothing goes through. Great what now??? Does anyone know the problem?? Have already thought about it. let the old original cables in and take them… And I definitely don’t want to drill!!! Please help me !!! Gruss Claudia
