I got my 65 GTO Convertible last July. It had a cassette player and the original Dash speaker. I have since gotten a period right push button radio and had it modified to get FM/AM and it has a port for downloading tunes. Now I looked at potentially putting stereo speakers in the vent openings but after some thought I really didn't want to change that. For as much time as I'll be listening to the radio I'm thinking I'd like to just replace the mono dash speaker with a new better speaker/speakers that would give me stereo? It that something that is possible? If so can you give me a pn/maker of such a speaker/speakers that will fit where the existing one sets? I did find a mono speaker to replace existing but I'd rather have some stereo even though the location is not optimal. The car is a non-AC car if that matters. Paul Kelley.
