Have the following problem, which also bothers me animally! Every time I turn on and off the radio or blob, or whatever I should describe it, my sub. I’ve heard that somehow it has to do with voltage spikes when switching on and off. If not, please teach me better, would be nice if I could get that away. But that’s not my main problem, that I can live with, which is much worse, the same problem also occurs when I am on the radio the L ied change or it’s over, also if I switch from CD to radio and vice versa and even if I set the radio to volume 0. Hope for quick help!! Thank you!
