Why would you use 4g power Then bust out the Speaker wire for a ground....? Use 4g for the ground aswell!

Braingetter Posted April 23, 2008 Report Share Posted April 23, 2008 rule of thumb is to always run the same size ground as the hot going to the amps....

sully Posted April 24, 2008 Report Share Posted April 24, 2008 It is the heat from the smaller wire that will cause problems. It tries to keep up with the current flow from the larger power wire and creates heat. I have seen the insulation melt on power wire before but never seen it catch anything on fire, only heard horror stories about people burning up cars from poor install or improper wire/fuse choice. Bolt the ground to bare metal on the body or frame of the car. If you don't feel confident doing that you can always run the wire directly back to the battery negative post.

Unique Alternatives Posted April 24, 2008 Report Share Posted April 24, 2008 Think of it like a push pull kinda situation, the power wire is pulling all the 4 guage current and is trying to dish it out to the ground but if its smaller theres alotta resistance there. I sometimes even make the ground larger than the power. Quote Link to comment Share on other sites More sharing options...
