I have 67 Convertible. The previous owner installed speakers in the kick panels. They are POS and the panels are shot. I'm replacing the kick panels and would rather leave them original since most of the posts I read indicate that the speaker/kick panel combos aren't much better. Has anyone had any luck with the dual speaker set ups that fit where the original dash speaker is? Do they really go in without modifications? How do they sound? Most of the supply sell good/better/best set ups. Are the differences noticable? Thanks to all who respond!
