Installed Infinity Kappa 682.9cf's front and rear
Added an amplified sub enclosure (can be read as, "inexpensive") in the trunk to improve the bass output. (12" JBL with remote and built in amp)
Nothing extraordinary to do as the topic has been covered quite a few times. With the 2012 and earlier speaker mounts up front, I decided to seal the gap from the inside of the adapter and mount the crossover to the right of each speaker.
One thing to point to out is the Premium's door subs really improve with some sound deadening. With the dedicated sub channels to tap into, the added sub hits quite well.
In a nutshell, it was worth the better part of a day to sound deaden the doors, upgrade the speakers and add the sub. Sound is very much improved.
