[QUOTE="adulbrich, post: 8379217, member: 661255"] A relay is a switch that you don't have to worry about in this case. Simply connect it's remote turn on to the remote turn on of your head unit or amp. Connect ground to ground. Connect battery positive to constant positive. Connect remote out to your volt meter's positive connection, and ground the negative of your volt meter. When the relay receives the 12v signal from your head unit, it will turn your volt meter on. Google relay, and there are lots of good in-depth explanations. I use a relay for all my amps, volt meter, and will also use it for cooling fans. [/QUOTE]
