Aftermarket amp remote wire for 2018 Nissan Kicks?

[fuelsaverkicks761]

I'm in the process of installing a new amp in my 2018 Kicks, and I could really use some help. I'm trying to locate the remote turn-on wire for the factory Bose amp. Does anyone have tips on the wiring, or maybe a reliable method to trigger the amp? I'd appreciate any advice you can offer

Can say this for certain, but I don't think the amp relies on a 12V signal, I think it uses data signal from the canbus, so good luck finding the signal. How about tapping into a fuse that sends power only when the ignition is on? Cigarette lighter for example

At this point, isn't relying on factory Bose wiring just making installs harder than they need to be? Wouldn't it be cleaner to bypass it entirely and run a dedicated remote signal?
