Hi all, came here looking for a 2019 Nissan Altima Radio Wiring Diagram, I’ve searched all over the internet and there isn’t one or it is eluding me.
Does anyone have this information? I am trying to find the AMP Remote wire so I can hook up an amp and sub.
Thank you!

couple wires to try here
tan pin 17 ignition
purple/white pin 1 amp turn on, may only work if you have bose system (not 100% sure)
may be another purple/white pin 7 that is acc
does the deck have bose or navigation or just a basic deck? new Nissan could have 2 different harness

I don’t have the Bose system installed , there are 2 wiring harnesses but I think one goes to the display.
I read that the 2019 Sentra remote wire is grey. Could they be related to Altima as well?

best thing to do is get a DMM an start testing wire, there are a few different harnesses in these. Even fwd and awd have different pin outs so its hard to pinpoint the 100% right one. You may be better off going to a cig. lighter plug if it turns off with the car. You should be using DMM and testing any wire anyone tells you to be safe. You may even have ANC mics in the car that have to be disconnected if your putting in a amp/sub

Thanks dude , I tried all the purple and tan and finally tapped the ignition. It was the last tan wire I tried.

Hello, could you possibly help me out with what wires you ended up using for the speakers? I can’t figure it out
