n ́evening, because I have often asked myself when reading some of the contributions, where it comes from partly (for my terms) enormous knowledge on the topic car-audio, I would like to bring in this experience, whether it comes from the profession or is simply a hobby. with some users here, I can almost not imagine that they have “only” acquired “by the way”, if yes, my respect. I have also often noticed that some sp ezis here are younger than I thought, what gives me a look at my own knowledge slight headache so, who likes, can post here his old, his profession and the way he got to car-audio. who doesn’t like it, just let me make the start: I am 21, time soldier (has quite little to do with car-audio ) and I got to car-hifi via the hobby home-hifi and wants and must definitely learn a lot more about it…if I’m getting my time off here I would definitely like to continue my professional life in this direction.
