I have done some searching and I must not know what to search for as I couldn't find any posts on this. I am sure there must be some out there though so I apologize in advance.
I am replacing the Kicker speakers in my Epic with wetsounds xs-650's. Currently there are 2 pair in the transom, and 3 pair in the boat. I got a killer deal on them and ended up getting 6 pairs of xs-650's. That leaves me with 1 set to place wherever I like. They can't go in the transom so I am left with mounting them somewhere in the boat. This brings me to my question. What is the best way to cut out the 5" hole for the speaker? Is it with a diamond coated 5" hole saw to make the perfect circle? I also seemed to have found that I should make a big square out of masking tape over the area to be drilled out. Is this how I should do it? Do I need to run the drill in reverse until I am through the gel coat?
