So far these are a great upgrade! They were a little snug so I had to really push them into place but once they got past that initial spot I was able to get them lined up perfectly. The top screws, nuts are a nightmare to work on but I got em both. You will need lock tight to secure the nuts once you have the screws set. No instructions included so I YouTubed it, pretty straightforward install. It deepened the sound just a little bit right at the tips, can’t hear a difference inside the car which is fine. They look great tho!
