should I do. 1 Fi 18" or 1 DC 18". I have finally gotten a new car. Exactly same as my last(I had no choice). And I sold the two fifteens to a friend and I want a new setup. The problem with the fifteens was that they didn't fit in my trunk with the box I wanted. So I had to make a ghetto box and deal with it. Now I want 1 18 so I can port the box to the right dimensions and make it all nice. So I need some Ideas. I will get a drawing of my trunk up asap
