    Install eBay Volt meter

    How would I wire this? I dont want it on 2-4-7. It says it comes with a pos + and a neg - wires. So I was just going to run the pos and neg from the volt meter to the pos and neg on my sub amp. But it willl be on continuously. So how do I get it from staying on all the time and is that the right way to wire it.

    Re: Install eBay Volt meter

    to wire up a 2-wire just use an ignition voltage wire behind the dash. it's the same as the battery voltage which is what you care about, and it turns off with the car.



    have you been helped by me? i'd love to know. shoot me a PM.

    measuring battery voltage will always read higher than at the amp because of voltage drop at the amp.

    the main reason to have a volt meter is to ensure your battery is properly charging - by making sure you achieve >13.8V while driving on a regular basis. for this purpose, monitoring at the head unit or dash is fine.
