Mac, why don't you cut a hole to the inside of the cockpit and mount hatch doors like in my v21?
That will give you good storage and access to that space. Why not try to mount kicker that way, instead of making a useless and undesireable hole in your splashwell? Even if it turns out that you can't get at it from the front, you will have a worthwhile modification. If need be, why not cut the backside out of the well with a dremel and then glass it back in after you mount your bracket?
