how do you measure the cutout diameter of a sub on a peice of wood. if it says 9 1/4"inch for a ten inch sub how do i measure a 9 1/4th"inch circle. or do i just divide that by 2 and make and start from a center point and draw a line 4 5/8"inches from the center ina circle

I just use the gasket unless you need a super tight fit. But yes u use half the size of the mounting diameter and draw a circle. 3rd grade math lol

If you don't have a drafting compass (for drawing circles), a pencil tied to a string works.

Measure said string so that tying it to your pencil gives you exactly 4 5/8" from the nail in the center and, voila!, you gots your 9 1/4" diameter circle
