ive never really had a "system" in a car, not one to warrant upgrading the charging system. but my brother does competitions in his trucks (he's been through a few trucks by now) his biggest one was in his older expedition. he took out the 3rd row seating and put a huge ported box in for 4 12's, atomic audio ELE's. he had 4 american bass amps, 1200 (real) rms watts to each one. then his 4 channel running the front and rear components. god... i think we ran 2 0 gauge wires, i cant even remember. all i remember is first he put in a ohio generator alternator, and he was having tons of dimming problems still, so bad that at night the dash would get so dim you couldn't read it. then he threw in 2 more gell cells (scosche ones) and it made it much much better, it still dimmed, but not as bad

they dont usually have as much cranking amps, but you can run them way down, and then charge them and there perfectly fine, unlike a convental battery which doesn't like that


but in smaller systems they eliminated alot if not all of the dimming

he just started stocking somthing called a "batt cap" im not sure exactly what it is, bu its supposed to be a mix between a battery and capacitor, there not very big either....dont know alot about them
