Question about Clarion APX400.4M Car Audio Amplifier
If you mean the "remote turn on" lead, you should connect this to a 12 volt remote turn on lead from your head unit or you can wire it to a 12 volt source that turns on when the key is turned on to start the vehicle. Wiring it to a dedicated remote turn on lead from the head unit is optimal though.
