12v Remote Connection

[succeed23]

I am connecting a RCA line output converter to my factory 2021 Ford F150 Larait with Factory subwoofer. What is the easiest place to add a remote wire for the amp? Has anyone tapped into the existing amp plug wires to turn on their secondary amp? Is there a fuse I can add that will turn the amp on and off when the radio is on/off?

I ended up using fuse #2. Amp turns on during acc, and cuts off when the door is open. Hope this saves someone time.
