Ah Gotcha, I have heard people doing rear and front but rear has more complications I guess, I’m looking for some plug n play options for the harness, do you have an amp for the speakers also what sub did you go with? Can you post some pics I also have a hybrid.
Looks clean especially the wiring of sub and amps, would post a detailed write up on it and where did you get that black trim for the rear trunk wall, looks so clean.
