After reading other reviews, they first said that they fit most 6.5 inch speakers. That is not right. Doesn't even come close to my Skar Audio 6.5. I had to use a dremmel to make the holes about half an inch larger. Now to my main point, I've added pictures to show the additional hardware I used to hold it in place and securely fasten it to the door. Comes with only two holes on the top to attach to doors. Literally almost fell off the door when I was closing it lol. So I drilled 3 more holes on top and 2 on bottom for additional fasteners. The holes are already in the door to use the extra latches they send you with these doors so all you have to do is drill through the plastic. I don't think you need to do this however, but I can't complain, I think after about 30 minutes I had them ready and fitted the way I wanted.
