Where do I find the remote wire to tap into

I have 2-10’s plus an amp all hooked up and ready to
go. I tapped into the green/brown and grey/black wires in the door sill using a converter. I tested it by running the remote wire from the new amp straight to the battery and it works perfectly(JUST TO TEST IT)
Obviously I need to tap into the factory remote wire, anyone know which wire it is?
Driver side door sill??
thanks in advance

 

The easiest way might be to use a fuse tap on a switched +12V circuit in the fuse box behind the glove box. Then run the wire down the door sill to the back.
