Hab ca trying times 4, which in my Audi A4 B5, built in 1995, behind Nokia built speakers with cables and terminal strips to connect. Bin completely desperate because in the small Audi isostecker with five cables, although responsible for butt LS, but semi-active, meaning armed only with wire nuts, can not be connected. Since helped put this in a very simple and effective way. Installation took 2 minutes and the original, although my little girl has put on the passenger seat countless questions.
Very well spent 10 because the LS really improve the sound. Double thumbs up!
