That or he could just make himself a kill switch?

If I'm doing a quick set-up like in a work car or something I always use a kill switch it's fast, it's easy and it works. If you want to do it the right way you should run it through a I/O relay. Some amps have a wire (blue I think) that will hook to a wire in the back of your stereo and will shut your amp off through the stereo when ever your car goes off (but this does not always work correctly with some amps).
