I just measured Exile SX65M... Hole starts close to 6 1/4" and full OD is around 6.9-7"... their inside diameter is 5.11
Can you tell me the diameter from mounting hole across to opposite mounting hole? That is the main concern with most of the 6.5's. I'd rather not add more to the budget at this point since I'm supposed to be looking for ways to pair it down.
Old enough to know better, young enough to do it anyway.
