[QUOTE="DidUHearThat?, post: 4826040, member: 594758"] ??? Those are not good engineering practices, certianly not something to recommend to a beginner. Even if 400 - 1000 amps did not cause a failure in the wire, if they are more than about 2 feet long you will experience voltage drop. The wire ratings I listed are the commonly accepted norms. Fuses will actually pass significatly more current than thier ratings for very short periods without popping. He has a 130 amp alternator and only needs 75 amps for his audio. 150 amp fuse is fine.
