Adding a digital volt meter

[mrpep]

I ordered a voltage meter for my van so I can observe voltage stability , drops etc etc . I know I can run wires from the battery but would like to take a short cut if there is one . Can I tap into the lighters positive and negative or must it be the battery ? Any other suggestions ??

I tapped into my amps positive and negative, so i knew exactly what my amp was getting voltage wise

Best way to do it is directly into your sub amp's voltage to know what the exact voltage of what your amp is seeing.

Did you run wires up to the drivers area so you see as you drive ?

in my truck that's how I did it. Ran one from amp pos and one from amp neg and ran wires with my other wires to the front and volt display sits right in the tray underneath where my head unit is. But not sure if anyone else has or not but I put a toggle switch on my pos wire so that way I can shut it off when the vehicles not running. There's probably a better way to do it but it works good for me.

I have three wire volt meter. One pos and one neg wire and then a remote wire for on and off. No need for toggle switch with three wire Meters... But to the OP yes you want you meter wires right at the amp so you know what voltage you amp is seeing.. That's the whole reason to have a volt meter.

Yes, just like how you ran rca's or your power wire. Under the carpet

Run a relay that turns on with your amp and connect it to the amp terminals for the constant positive and ground. Then run wires up to your dash for the volt meter

With that meter you'll need a relay that switches the display on using the remote turn on wire.

If your running two monoblock amps strapped do you use one or two meters? And why?

yes, that how i did mine.

that why there no switch.

it will turn on when your amps turn on.

I run a switch just cuz LED are bright as **** at night and i like to ride in darkness.

Can anyone post a link to a relay ? I don't want to get the wrong one ..

Can someone answer my question please

I'm assuming that one would do since you'll be getting your voltage from the same source.
