Right now I have a 130 amp alt. and will be stuck with it for awhile //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif. I had some scrap 4 gauge (tsunami) laying around that I did the big 3 with. I was going to order some knukonceptz Kolossus 1/0 to redo it with. Although a few places ive seen shows that the 4 gauge is good enough with 130 amp alt? Do you guys think I will see that much of an advantage going with the kolossus/is it worth the ~$40?
