Howe do you hook up the remote amp turn -on without a specific wire for it in the diagram ? ( Acura rsx 2003.)
Brian, technically you could connect your 2003 Acura RSX amplifier turn on wire to the radio switched 12v+ wire. That way your amplifier is on whenever your 2003 Acura RSX is on and off whenever your 2003 Acura RSX is off. Just make sure to run an in-line fuse holder with a 1-amp fuse on the amplifier turn on wire. Hope this helps. Good luck with your install.
