Hey so I’m in the process of adding a subwoofer box to my HIFI system, I’m planning on tapping the wires in the trunk to get audio to the subwoofer amp, does anyone know what are the colors that i should tap into, i don’t really know which ones are responsible for the low/bass signal

Also, the subwoofer amp needs a remote wire to turn on, does anyone know a good place to get a 12v signal that only turns on when the car is on?
