Thanks for the love guys. The springs, to me, have felt exactly the same as the msport ones did. I was worried they wouldn't but it has been great. The main difference is the car feels more grounded. It hugs the road more and corners like a sports car. All modes ride the same and I have switched back and forth between comfort and sport +.
I cant really take pics of the sub because it is behind a beauty board in the trunk of the car. I had a ported box built for the 12 because I wanted the same thing you did. Just some more bottom for when the windows are down and you want to hear it drop. Wasn't a crazy install. Had a box made pushed to back of trunk then covered it up. Cuts the trunk in half but gives me what I wanted.
