How do the hell do I see if my voltage is dropping below 12 volts or not? When I use a multimeter on DC on the amp it shows negative when the leads are postive to postive and negative to negative but when I reverse postive and negative to negative and postive it's not negative. And it's also dropping to zero so I'm doing something wrong or something. (The one with a negative is postive prob to postive speaker wire and negative to negative.)(the one with a postive number is postive prob to negative speaker wire and negative to postive) and it's not showing 12 volts or am I doing this wrong. The back up battery shows 13.86 volts when music is playing so I'm just confused
