Hello together I bought a Trabi together with my girlfriend and we are now restoring it together One way forward: the sound system should remain low budget. A radio in retrolook we have already looked out:https://www.amazon.de/…/?… As boxing only the installation place hat rack is possible, since the previous owner has already brought holes there. In the doors and in the dashboard no loudspeakers come into question because of original optics. I want the contemporary ball boxes w Can you recommend to me loudspeakers that I can install in the hat rack, which sound good on their own?
