2nd batt. or h.o. alt?

[basswiigee]

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 ?

The alternator is the source of the power supply. It should always be the first upgrade. Batteries don't make current they only store whatever passes through them. If there is nothing to pass there is nothing to store.

From your explanation I'd have to say the alt. if its going bad adding a second battery to it isn't going to help it at all.

Get a bigger Alternator.
