Ok, so here is the problem. I just installed a new system in a car and it has the battery up under the wheel well(Chrysler) and then there are posts up under the hood for Pos/Neg. I ran my 1/0 to the positive post under the hood back to my amps and grounded in my trunk. New Dakota Digital voltage meter installed and when the system is turned up, she drops to as low as 9.5, which obviously is gonna kill my shit quickly. I've got an alt on the way and will do a 2nd battery as well,but I am getting different opinions as where I should have my positive wire up front. Should it go directly to the battery under the wheel well or to the positive post under the hood. Were only talking 2000 watts so it shouldn't be quite so low.Here are some stock pics and not showing the stereo power wire as it is dark out right now. Any help would be appreciated. Also, with the way this car is wired, I am getting some who think using 4 gauge instead of 1/0 would be better for the big 3 part of the wiring, which doesn't seem logical, but that's why I am asking. It's all top if the line wire, (KNU), amps, everything. HHMMMMMM??????
