Why even post this thread if all you're going to do is discount what everyone says to you?
Childish, why not just make a thread that says "hey guys I've got a dc lvl 3 and im gonna run 1100 rms to it, brb while i blow it up."
I suggest you go out and actually test the things you say.
Seriously, go find a car with a stock amp, measure the voltage drops with one battery and then with two.
You'll find that your precious little link that you spam all around here is nothing but dumb.
