The two piece bimini that came with my boat (reverse arch) has circular openings in the cloth that allow for the installation of tower speakers in the standard location, my problem is that there are no predrilled holes allowing for internal wiring. NMJim has pics on this thread that show the speakers installed on the reverse arch tower. (
