I'm currently driving an 2015 Focus SE. The factory sound, I think, is pretty good. Quality does change if I set the sound to driver sound or passengers. It has plenty of bass and is pretty good for a factory stereo. I'm not an audiophile by any means, but I've heard rumbles of bad speaker...
As far as I know the order banks are still open. I guess it’s safe to assume Ford priced out a decent amount of people. If in fact they can do 10 to 11,000 per month I'm wondering if delivery times will improve? One can hope, right?
