I'd previously installed these Hybrid Audio Unity component speakers in his old 4Runner and then he sold that and upgraded....but he didn't want to break-up with his old sound system....so he removed that and kept them for his new ride.....smart move...because the newer Toyota speakers still sounded like junk.
I fabricated a custom speaker adapter for each side and then did some sound deadening to create a 'sub-box' like effect in the doors.
In the future, we'll be adding an amplifier and a unique mid-bass upgrade....so look out for that one.
