3rd gen non-jbl speaker impedance?

Starting my audio build this coming weekend, and i need to figure out some wiring. But first I need to know the factory speaker impedance.

The speakers I got are 2 ohms, but I am building a 3 way system using jbl 20m mid-range speaker. the way I plan to run them, I will have two 2 ohm sets running per side. The way I think the factory wiring is set up, the speakers will be pushing a 1 ohm load, but with a little swapping I should be able to run at 4 ohms.

From what I hear, the factory jbl system runs 2 ohm speakers. Are the non-jbl also 2 ohm, or 4 ohm

 

Non-jbl are 4ohm
