So I bought the sky high audio 1/0 big 3 kit and installed it today. I ran one from positive alternator post to positive battery post. One from negative battery post to ground. And one from the engine block to a body ground. All 1/0. Got in and played a little music and my voltage still dropped to 12.4... I have no clue what I could’ve done wrong, it’s only a 1200 watt amp wired to .5 ohms. I checked voltage at alternator and battery and it’s at 13.75. Which is what my voltage reader is reading at idle but when I turn the bass up it still drops. Lmk if you have any idea of what it could be.
