Hello hertzkasper, with all due respect for your meticulousness, your expertise and the great effort you make to give your knowledge to everyone. I have some questions as an older semester. Why do you and your readers spend so much time, money and work on this audio upgrade of your vehicles? Television is already offered, as I read. Is it not enough to focus fully on driving, the sonorous sound of the engine to lukewarmly Do you enjoy this at all when music or language penetrates your brain cells from all directions or pipes? Do you not get distracted by the variety of impressions while driving? When I imagine how many cars I have to drive, do you not get distracted by the variety of impressions during driving? mobilising through this noise during their work, and driving a car is work, being distracted, many things do not surprise me any more on our streets. No offense, but personally this whole effort is creepy to me, I don’t want to talk about the additional costs at all.
