For optimum performance, it is important for the tweeters to focus accurately on the audience. There are various ways to install the tweeters, however, DrShaggy advised me to focus the front tweeters to headrest of the opposite sides.
The focal tweeters come with two types of sockets .. one for installation on the dashboard surface, and the other for installation in a hole. I had installed them on the surface, but owing to curvature of the surface of the dashboard, I could not achieve proper focus.
Therefore, it was time to focus them properly.
