Hello, as the title already shows, I wanted to expand the original basic and instead install an Alpine. What do I have to consider? How do I get the original out? Do I need antenna adapters etc.? Do I have a fortwo without sound system. Did I want to buy later sound converter enclosures and build in my own boxes. Perhaps also wanted to get doorboards with boxes. Maybe someone has experience with it? How do I best put the cable in the doors? I didn’t want to install an amplifier and not spend a lot of money. Should only sound good. I am very grateful for all the tips. I wanted to inquire before I started. [From motor talk from the topic ‘extend original radio and install Alpine’ transferred.]
