Im gonna use my friend's DMM to set the gains on my sub amp and speaker amp. Well, i breifly read the sticky, and noticed some people saying the ideal voltage is like 35 volts on their amp. How the hell do you get such a high voltage? Don't most car batteries only go up to 14.4 or so? Am i missing something here? Also, what mode to you put the DMM on to measure voltage on the amp to set the gains? I apologize if this is a dumb question, but im very confused.
