I didnt bother reading everything that was written. But for a good SQ build JBL and Alpine have reall good stuff and you dont have to worry about special ordering. I know there are better out there. But you would probably have to special order them or buy online. Which some people dont want to do or cant.

But I found in the stores JBL and Alpine have the best sound out there. And if your getting a sub and amp they are all the same really. Its the box you gotta look for.
