I am confused on how to wire the wiring harness for the head unit

[keep_hope_alive]

I never used factory ground when installing an amp. Too much resistance in the factory ground. Ground HU to chassis.

Not the blue wire!!! Blue/white wire on the head unit is amp turn on. Blue is for antenna, only on when radio is on.

good catch, & yes it appears he is correct.

So I connected the blue wire to the blue and remote turn on to the blue/white and my antenna doesnt come out of my car.

Should i connect BOTH the blue and remote turn on wire from my harness to the HU blue/white?

nvm i added the facotry amp harness but instead connected my remote turn on wire to its amp turn on(originally for factory amp)

and then but antenna from harness to Blue/white on HU
