I just did the driver side door speaker. No wiring for a tweeter on my 2015 L. VERY easy to take off the sail, though. Just one clip (pull from the front).
I have another question for anyone who can offer some help. How the heck do you separate the wiring harness for the power locks in the door?!!
I did the speaker with the door interior hanging and me holding it with my head. I felt like an idiot, but I just couldn't unplug it and I was afraid of breaking it. I still have the passenger side to do, so any hints would be appreciated.
