SAN Interior Speaker Install

I am looking for the old threads where I think Grant shows his install of 6.5 interior speakers in a SAN. I have a signature series with no interior speakers and am gettin ready for summer and want to install 6 Momo's in the stock locations. The factory already cut the holes but I want to know how to properly install the speakers flush. If anyone else has photos they would be greatly appreciated!! I'm pretty nervous about cutting the vinyl and want to do it correctly.

Thanks!!
