Will be cutting the holes for a Tumult and 18PR's this weekend and I just want some cutout conformation. I have been IMed this info before, but I was "smart enough" NOT to write it down From Adire, I got 14 1/8" cutout, 15.5" flush mount (tight fit, so use 15 5/8), and 3/4" deep. Since I got it straight from the horses mouth, they should be good For the 18PR's from Stryke, I don't have any info directly from stryke. I measured the flush mount diameter and depth. I got 18 1/2" ...which is tight, so I will use 18 5/8" x 3/4" deep. I am not sure of the cutout diameter since I can't easy get the tap in place. I think it needs to be 16.5". Any conformations? Thanks!
