right just got text says he checked everything i'm gonna make him get smaller fuse at amp i'd rather fuse blow than amp.. if ya'll will re read my post at top and see if he has that done wrong or is it ok to do big 3 to both batts and then just run amp off 1st batt cause i ain't used to that i only seen batts in back not 2 under hood.. he said he'd come over take amp out (it's mounted to back wall of his truck and i can't see settings back there looking upside down and sideways) so i can check his settings at least., i preset it for him but he installed it 3 days later and i never really got to adjust it.. if anything i shoulda had it set to low for his pos 2v jvc, if he had different type truck my old orion hp's would be loud af in there but that dam*n cabin ***** (yeah idk trucks) same subs same box in my car with 700 rms crossfire amp was destroying my car years ago thats y i went to 1 sub but now both of them in his truck aren't as loud as my pioneer..
