As many of you know the 1976 corvette, and down I think, did not come with rear speakers. T-Tops off, windows down, radio cranked all the way up, and you can't really hear the best, even with replacement speakers. Has anyone out there put in rear speakers? I don't want to go with a box, as to there would be no room for my t-tops. Any help as to putting in rear speakers would be greatly appreciated.
