Im a show-off and have a booming system in my ride. So, I use the killswitch so the boom and the screen stays up until i hit the switch. Call me a poser if you like, just me.
If you use the ignition switch you wont have to worry about getting sidetracked and forgetting to switch off the ignition only to come back and find a really dim headlight!
