Posted on Monday, March 06, 2006 - 15:50 GMT You must match the power and ground wires. |

Posted on Monday, March 06, 2006 - 15:58 GMT well, just remember that it's all one circuit from the battery to the amp to ground, and back to the battery.. so the gauge of wire is determined (throughout the circuit) by the length of the wire (total) and current it carries.
going bigger than required doesn't hurt anything.

Posted on Tuesday, March 07, 2006 - 21:32 GMT It's a matter of resistance and the resulting voltage drop - which depends on the current you're drawing and the length of the ground wire.
For example, if your ground is 5' and your amps can draw 100A --
2 ga would drop less than .08v
5 ga about .16v
8 ga about .31v
The only one that raises an eyebrow is 8 ga, and if your ground is shorter, or your system draws less than 100A the effect will be even less.
It just doesn't make much sense to run the long 5 ga wire to avoid a big voltage drop only to go small on the ground. |
