Dear Foristi, U.S. car lover, At the beginning of this thread I don’t even know if it will be a technical inquiry or more the attempt to silence one’s own scruples. What is it about? My Cadillac Sedan DeVille, built in 1966 cruist casually bubbling and barely audible with his 7 liter engine when I perform it in beautiful weather. That’s true Ami – pleasure…. It is equipped with a relatively simple original radio with FM and AM station keys, a retractable As the separation sharpness of the transmitters is probably not designed for the European FM transmitters and things like AFC or RDS are of course foreign, the radio is always silent and represents “only” an optical eye-catcher. Therefore, I consider whether I should upgrade my caddy “acoustically”. It would have been interesting to listen to Frank Sinatra, Glenn Miller or Elvis from ordinary loudspeakers at the next exit. d but it must have come to considerable interventions into the originality of the interior equipment. Whether this intervention is well worth the originality? Are there small, gently installed loudspeakers and / or terminal devices, which may be more or less “hidden” and who should do that? I don’t want to let any AUtoradio people get into my caddy. I’m just interested in your opinion Dear Greetings Katweazel
