I am about to pull the trigger on 3 sa-12's and a ct sounds 2500.1
my plan is to run my main battery (optima red top) 2nd battery under the hood (xs power D3400=3300amps) already have the 0 gauge big 3. one run each of 0(+ and -) to 2 (xs power D680's =2000 amps) in the rear and ground both rear battries in the rear of the truck somewhere.
my questions are....can you have too may ground points and will my stock 160 amp alt handle that? if not will a high output alt be better of with adding a 2nd alt be better
thanks for any help guys
