hello have the following problem: when I start the engine, the tweeters give his sound (quiet) again, according to the speed. I already read older contributions to this topic, but would like to post it here anyway, because I have already checked the most likely sources of error. the worst thing is: I bought new chinch cables and put them across the car over the seats, after that the noise was even stronger! how is that, or what bothers the transmission? ndreas
