Car Audio Amplifier Bose How to turn it on

[skynet85]

I am have 2012-2015y FIAT 500 Audio Amplifier Bose OEM 3284780030
when connect the power to pin C4 + and pin C8 - it does not react, I think that you still need to use some kind of contact to turn it on, I found the pinout but I can't figure out what to use

the pin marked "remote" probably needs 12v or ground to power it up.
a bigger concern is the GPIO inputs
it may switch the number of speaker outputs based on what car it thinks it's in.
also - PWM???
maybe it monitors the cars speed to ajust the volume
