Purchased rear door 6.5" rings to test out on my 2023 f-150 lightning ER XLT with basic audio package. The material is great but I had to make 2 mods. The first was I had to make the opening bigger to fit the audison voce components I was using. That's on me. The second was the holes for mounting onto the door panel had to be opened at the surface to allow the factory bolt screw heads to resess so they could be reused and have enough threads to make it through the door and out.
I also want to add the foam you include for the mounting rings is too thin because of the factory fasteners sit raised above the panel higher than your included foam gasket. Doubling it solved the issues but I didnt have enough for the other door and had to go out and purchase additional.
These little attention to details is why I am only giving it 3 stars. However the rings themselves are well made and so much better than the old days making MDF rings with glue, pin nails and hand cutting, sanding and sealing. :-)
The picture is before my mods. You can see how the factory screw bolts sit on top.
