While we do not offer any specific in dash radios for the 1947-1953 Cadillac, we do offer other effective options that will give you great sound in your vintage Cadillac. Our hidden radios are some of our best selling products for a reason. Many people like to keep their old radio in the dash for that correct look. So the hidden radio is a great option that will still give great sound. To go along with that, we also have many other audio components that you can add to your vehicle such as speakers, subwoofers, and antennas.
