Evening! I once asked myself which method is best to connect 2 sound recorder cables with each other. Situation with my frontsys is that I left the original cable in the area of the door plug, i.e. from the interior to the door, because I have seen no other way to get my 4qmm speaker cables into the doors besides drills. That’s why I used the two cables together and then went right into the door again to the 4qmm. Now I want to know , which method would be best (audiophilic) to connect speaker cables? Luscious clamps? Soldering? And if soldering is the best method, which is the second best? Since I am not exactly a fine motorist and there are still a lot of cables and there is hardly any space, I did not want to solder, because I otherwise damage the other cables or anything else with the hot piston. Thank you for your answers!!!!
