All I can say is what a difference from those factory "Premium" models! I compared them side by side (pics below) and I was shocked to find the "good" stereo from Ford was 20W?! The new ones are only mid-range (opposed to mid-bass) and can still vibrate your back!

They are 160W each and I highly reccomend getting all FOUR doors done. These rear speakers are more than just "fill" as I discovered when installing the fronts only for a few weeks. With the rear speakers added, well, words can't say enough.
