Hi, I have had a pair of KG 4’s for a while and ordered new crossovers from Bob Crites to update these speakers. I am not sure how you do the removal and then install of these crossovers. I thought you gained access by removing the passive radiator, but that seems to be glued down. It also seems like there might extra wires on the new crossover. This is my first time attempting opening a speaker and want to make sure I am doing it right. Thanks, Brian
