4ga should be ok right?

minimum 2ga.

1 or 0 are better.

The rally conversion is running 2ga, 4 for the stereo.

If you've fused it...it you might be okay. Not ideal, but maybe okay.

well it came with a 100a fuse.. dont know if that is enough. i dont plan on keeping it permanent. just something for now. im looking at summit racings solution for the relocation. sounds sweet.

less power loss
