WOLFRAM FTW
he's 30 miles away so not much i can do.. i told him check grounds make sure no paint under them.. he has 2 batts under hood main start batt powers amp has big 3 wires on it + wires ran to 2 batt under hood and i think he did big 3 on 2nd batt too.. should he have ran from alt to start batt to 2nd batt back to amp instead of just adding 2nd batt and not running amp from it? i told him i was used to seeing 2 batt at amp so idk if his way was good or not but i wouldn't have done it that way.. other concern is all those grounds under hood could have gotta oil on them or something idk.. i as what amp fuse he has at the amp idk yet, but if he has like 250 amp fuse is that to big for that amp even with 0ga wire?
