The hole in the door behind the panel is about 6" in diameter, but odd
shaped.  Best not to cut any metal though, there is a tube for the window
regulator cable that runs behind the front edge.

I'm also installing new speakers and electric windows to avoid the winder
clearance problem.

Subject: Speaker Install Question

Hi, i was wondering if anyone has ever used a hole saw or a circle cutter on
a mounted front door panel? I was thinking about installing 5" speakers,
could I do this by expanding the 4" hole in the with the panel mounted if I
were careful?  This on an  84 Westy without  power windows. Still working on
my audio mojo. Thanks in advance.
