So I was looking at adding 2 lower spec'd sealed glass batts to the back in place of a single more expensive one that is of similar rating to 2 of the cheaper lower spec'd ones
tryin to save a hundred bucks or so on budget
do i need to wire differently? or just all pos to pos / neg to neg on all 3 batts (front underhood to rear #1 to rear #2)
figured it'd be how i'm thinking it is or ???
