Thanks Kevin, yes I have 0 gauge since im installing a subwoofer. I will be replacing the alternator with either a high output aftermarket alt or getting mine rebuild for more amps. I will be installing a sundown x10 with a hifonics brutus amp at 1ohm 2000watts. Waay to much but I can always go down to 750 rms at 4 ohm.
I seen ppl doing the big 3 but wasnt sure on alt. Already did 0 gauge grounds, 0 gauge batt to starter and 8 gauge battery to fuse box.
