Even for a well-secured wire running from a trunk-mounted battery to the starter solenoid at the front of the car? I should think a single length of stranded 0-gauge wire will work well here. > 1st hit on google: > http://www.google.ca/search?hl=en&ie=ISO-8859-1&q=gauge+copper+wire+resista >nce+per+foot&btnG=Google+Search&meta= > > ---- > Solid wire diameters increases/decreases by a factor of 2 every 6 > gages. > --<\quote>-- > therefore, diameter=(5 AWG is 181.9 thousandths of an inch) X 2 > or .... 0AWG= 363.8 thousandths of an inch > > ---- > So, one simple result of this is that if you take two strands the same > gauge, it's the equivalent of a single wire that's 3 gauges lower.

It's all in the search terms I guess (I used things including 0-gauge, 1-gauge, automotive wire, etc).
