i'd say the cutout hole is roughly the same shape as the new door card but 75% smaller than it. so, it's a decent chunk that comes out. my door panels and the doors themselves are layered in STP Black Magic sound deadening. Nothing in my door rattles. It's like a lead brick.

Have you had in rattles or annoying vibration?
