ground resistance/rca voltage
#1
so resently i purchased a dmm.i wanted to check how much resistance my grounds actually had. it gave me a reading of .40 or .040 cant remember which .is this good or bad [img]graemlins/dunno.gif[/img]
my alpine 9827 is supposed to have 4 volt preouts so i thought i would check it. i turned off the speakers and cranked up the volume to the max and it gave me a reading of 7 volts [img]graemlins/freak.gif[/img] is this right. i know with the volume that high i would be a clipped signal.but is it supposed to read over 4 volts? i never listen to it with the volume over 12 out of 35 anyway

.40 is too high or not right. .040 sounds ok.
I'm not familiar with preout "laws" sort of speak
What kind of signal was it a tone or music?
Here's where I get confused, is that 7 volts RMS or no? .707 * 7 volts is 4.9 Or do decks generally put out that much voltage?
