I own a 2015 Supra 550 SE, I would like to add 2 new tower speakers to my tower. I currently have the 2 stock Polk tower speakers that swivel on top of the tower. I have 2 REV 8s off of a boat I sold a few years ago and would like to add them the the lower part of the tower that currently has the blank plate installed. Has any body seen or heard of any type of adapter to mount the wet sounds speakers to this year Supra tower?? I can find the Polk adapter for Polk speakers but would prefer to use the speakers I currently own.
