The install wasn't "smooth" not because of the speakers because of the Fiberglass and plywood where I installed them. I needed to make a larger hole then I had with a larger whole saw (not simple as there is not a great way to center) That said though they are the best sounding speaker I have installed on my boat (30' sailboat) They are exposed to the weather, sun, rain and the occasional foot, lets see how they do. I have had many less expensive speaker die in the same location. So-far though I'm very impressed!
