I have a 1999 Hunter 380. The interior speakers, which are square, are literally disintegrating. (see picture) They are 6.5 inches square and I can't find replacements. If I went with round ones the opening to the back would need to be a circle with a 5 inch diameter, (without enlarging it), and would need to be 7 inch in the front to hide the 4 screw wholes from the previous speakers. Has anyone changed these out and do they have a recommendation?
Thank you
Tom
