My first car was a 67 chevelle with AM only. The first mod was a AM/FM converter by Audiovox.I remember all of those except adding only one speaker in the back. For me it was always AM radio until I saved up enough money to go to RadioShack for a stereo and TWO, yes TWO, 6 x 9s. Actually, now that I think about it, my very first car never even had an AM radio from the factory so it took a little longer to save up the extra money to also get an antenna.
