i'd definitely appreciate some more definitive testing then 'my buddies buddy said it's gud'...
it was warmer today, so opened up the passenger side door.
the hole is 157mm/6.181" in diameter
depth to window from sheet metal is 70mm/2.756"
depth of interior door panel to sheet metal is roughly 45mm/1.771"(speaker angled in door, so slightly more on one side, slightly less on the other side)
no apologies for metric measurements. my first exposure to tools was working on bikes, and everything is metric there, so i almost know it better then imperial..
the rolled down window takes up the top-rear portion of the opening. neodymium motors might bypass it for 'bonus depth', but probably not.
