I'm purchasing a '67 RS Convertible this week and it only has the one speaker on the top of the dash. The previous owner upgraded the stereo to a 100 watt aftermarket model that fits in the original radio hole and upgraded the speaker to a dual tweeter style. I was wondering, did convertibles with the am/fm 8-Track option have 2 speakers (in the doors or kick panels?). I know there was a 4 speaker option for coupes, so I'm assuming two of them were up front. Any help would be appreciated.
