Hello, I have already searched here and in the Golf 4-Forum, but only found something that has to do with subsequent installation. In my Bora suddenly (today still works normally) no heights can be heard anymore. I already tried to listen directly to the tweeters and think that on both sides the tweeters don’t sound. Now I have the question: What is the likely error? Problem on the radio (Kenwood)? Or does the Golf 4/ Bora have a (or 2) crossover(s)? This makes it strange that it suddenly doesn’t work overnight. Since I have to degrade the whole TV during speaker check-up or exchange, I might first look behind the radio. Or if it could be the radio directly, replace it immediately. In the manual “This is done” only the insertion and extension of the LS is described, no info about crossover Thanks for tips.
