Silver Member Username: FandimReno, Nevada United State... Post Number: 794 Registered: Jun-05 | The wires cant carry more current than is available, though, is your problem.. Your battery fully charged is around 12.6 volts, and most alternators are 13.8 - 14.8 volts. What's happening, is when your bass hits, you're exceeding the supply of current your alternator can produce, so what's happening is your battery is then supplying it's stored power, but the voltage is not as high from your battery, so there is a difference in the illumination of your lights. Adding a larger wire size, wont let your alternator produce more current, and at 70 amps.. chances are your stock wiring can already carry that load - with no real loss in voltage due to resistance of the wire. |
