Dear forum, sometimes a few dummy questions: 1) External subwoofer connected to high-level connectors changes its volume over the turn’ on the radio. Is that the same with the chinch inputs (line-in)? Does a high-low adapter not hit a fixed volume, but is the “line out” signal guided linearly to the radio volume? 2) Is an LS connection to which a high-low adapter still hangs to connect to speakers, or are the channels virtually gone because it is connected to the impedan z then doesn’t work out anymore? Look forward to tips
