Alright so tomorrow I am going to be cutting the wholes for my subs, but I just thought about it, and Im not quiet sure on what size i should cut them. They are 10 inch arsenals. The whole sub is 11 inches, and the outer rim is 3/4 of an inch, So i was thinking that 9 1/2 would be good, but a little small, so i figured maybe like 9 9/16 of an inch would be a nice size hole. Does that sound right? thanks
