The other day I went to my local hardware store and purchased a small sheet of 22 guage steel (12"x18"...$4).
With this, I made my own adapter plates for the front dash, took about an hour and a half total time. Everything mounts up just fine....except, I don't have a 4 1/2" hole saw, and don't plan on buying one ($30+).
So my dilema is, now I have perfect adapter blanks and no way to cut the hole for the actual speakers. I was thinking about tracing out the circle, drilling holes on the trace line, then following through with a hack saw blade.
Any ideas to make this any easier?
