Close enough to 70 Amps!
Dave, another great thesis and its awesome to see Ohms law getting a workout on MySandman. With reagrds to the current draw, i have seen this in action. I had a Sony X-Plod (1000W RMS branded) amp running two Alpine 12 inch subs some years ago and suffered several failed alternators in my VT 5lt common door. I connected an amp meter to the alternator wire and measured a max draw of 120A with everything on such as headlights, A/C, sound system up full etc etc. Its an area not many people think about.
