I’m looking to install components and use factory wiring for now. I saw another thread stating the radio has 2 front and 2 rear outputs, is that true?

in my 2004 Avalanche, the tweeters and door speakers were wired in parallel. I found where the wires split and put my crossover there. is the G8 similar and is so, where in the car is the wiring split?

if I go with 4 ohm speakers, what impedance resistor would you use on the center? I’m usually a rear fade setting 3 kind of guy to get an even volume around me.

i do plan on using the factory amp for awhile until I perfect the system in my daily driver. Car is 2009 GXP.
