Having 8ga wire is not why your getting voltage drops. The 8ga is restricting current flow, upgrading to bigger wire will allow more current to flow thus ******* more current from your electrical system causing more voltage drops. To stop voltage drops get a nice new battery, something big, if that doesn't do it depending on your stock alt size you might want to get a new alt. And on top of that there is no point AT ALL to use 1/0 for your big three on a stock alternator. 1/0 is good for 300 amps and your stock alternator is probably only 80-100 amps depending on your vehicle. The stock wiring is probably fine as is.</blockquote>
