I don't mind admitting it, I was very apprehensive about cutting a hole in my boat/dash to start the install process of the new radio.
Ask me to cut a hole in the side of a house to put in a new window.....no problemo!
So I took my time, checked behind the cut out area for no wires, switches or anything I'd be sorry I cut through.
I made a plywood template and marked the area to be cut with a felt pen, drilled a hole in each corner and then took the multi saw and cut those felt marker lines.
Installing the cover plate was easy, drill four holes and bolt it in place.
Hard part ( I hope) is done.
