I don't blame you for not believeing me. The reason I did it is because I have stock electrical, I did it after I first installed my system, because it is more powerful than I should be running off stock electrical especially because I couldn't connect the alt-bat of the big 3 I was worried that I might have a situation where I would be discharging my battery and I could walk out to my car after work or somewhere and have a dead battery. So I decided to do this test to see how she held up. I was at my cabin in bemidji with acres upon acres to myself no cops were called. I didn't believe it either man, I got done playing it for 30 minutes, I'm not sure at what hz exactly but i was using DR crankenstein track 02 has that constant tone for the whole time on repeat. I hooked up a charger to the battery afterward to see how much I had to charge her, and I was totally amazed when my 2amp charge showed a green light after only a few minutes.
