Finally got around to putting my sub in today from my f150. I was really surprised how mich less sound insulation this 2017 f250 xlt has vs my 2015 xlt f150. Sub fits nicely and well continually makes me want to mess with the sony system in my 2016 f350.... The factory speakers in these aluminum trucks are seriously a joke. Worse than the previous gen trucks

 

I replaced all mine a few months ago and added a 10" sub. What a difference it made! Ya I actually laughed out loud when I saw the size of the magnet on the factory speakers.

 

They were a joke. It was one of my favorite upgrades to the "office"
