amperage meter schematic needed

I have 2 power meters for my car audio but after a amp meter for it too so i can see the current draw all the time, pref digital,

if anyone knows of a circit or schematics please leave a link.

thanks in advance.

 Not sure if you're looking for a temp installed meter or a permanent one; how much current are you expecting to draw and where do you want to mount the display?

Basically i want to add this digital readout to my main power in 0 gauge line so i can see how many amps my system is drawing.

Thanks

 Where do you want the display mounted?..

How much current are you expecting to see?.

Is this to be a permanently mounted meter?

In my boot i have 0 gauge cable comming in to a disroblock with a volt meter built into it, then 2 4 gauge cable out , i want it just before the distro block so i can see what the total current my system is drawing.

not sure, a 3 digit 7 seg display should be good enough, think the amperage would be round 60 - 100.

yes this is to be prem mounted in a perspex box i will make.

Thanks for your help.

 Look into using a shunt to measure that amount of current.. best places to look would be a motor home parts company, or something for automotive charging systems.

Any ideas where to get a schematic for it?

thanks
