New 2015 Owner - First Z

Just picked up a new base model 6-speed -- loving it so far...

Had been lurking on the forum prior to purchase, and have some questions.

I plan to do a full dynamat & dynaliner install on the doors and rear bay. Seems to be pretty good DIYs on door panel removal and removing all the panels from the rear bay. This brings me to some questions about upgrading speakers.

Have no real intention of replacing the HU as this 2015 has bluetooth & USB audio integrated, and I use my iPhone for navigation. Which brings me to upgrading speakers. Stock is dash tweeter and door mid/woofer.

1) If I want to upgrade speakers do these each receive a full range signal from the HU or is there a crossover somewhere??

2) Are the tweeter and mid powered separately -- or is the signal just split or crossover somewhere coming off the HU??

3) Are there any factory wiring harness adapters available so I don't have to cut into factory wiring??

Can't seem to find any info on these things and will help me better determine what I will do / if anything.

Appreciate the help...
