I had no Idea about the possibilities of car hifi (of course I installed an amplifier and a basstube in my earlier cars when I was younger, but I don't want a "squawk box" again).

So instead of just loud speakers I wanted to have  coordinated components. For that I went to the car-hifi specialist of my choice: Steffen CarHifi in Hausen (Brugg).

There I could not only test-hear various systems but I could also test-hear zwo different solutions directly in a car. Then we made a raw cost estimate and I thought about it for a few days.
Result: I don't need a big show system, I just want to have a great sound in the (loud) van.

At the end I decided to buy:

• amplifier: Radion 90.4 by Audiosystem
• mid-range and tweeter speaker set: Radion 165 by Audiosystem
• Woofer: Radion 12 Plus by Audiosystem
• plus all needed cables and fuses

Later we will build a bandpass-box for the woofer by ourself.
Today we connected all components for a small test. Even the Retrostyle Radio in the 70ties-Look was allowed to play MP3-files for the first time. It all worked perfectly!
