I don't quite understand what you mean Scott. How much EMF is given off by the 2 electronic devices (stereo amplifier and automatic charging relay) I have under the seat? 

The third device I have under there, a trickle charger, is not used when I am driving as I have not found a long enough extension cord.

And can you tell me the field size and strength of any EMF given off from copper wire carrying less than 20 Amp DC current?
