I'm hoping someone on here has a good minimally invasive solution here. I have a 2010 Focus, and I have mounted my Lil Wil on the trunk lid, running the coax down the front edge into the trunk then up to the radio. The issue I have is going thru the car wash the other day I had a lot of water get in, as the coax is not letting the trunk seal work properly. I figure if the car wash can get in there, this winter the melting snow will make it in too. Is there a way to run the coax that I do not have to worry about leaks?
