i got 4 12's, 2000d amp [getting 1750w out of it] @ 1ohm, got all 0ga including big 3, optima yellow top, lights still dim and yesterday i either killed the batt. or the alternator [which was 9yrs old] or both... lol about to buy new stuff... but on a budget [prices are crazy] so should i replace stock 140a alt. and add second batt. OR get a h.o. alt and run a single agm ?
