okay okay i've been reading al lthis time and i've got a question. Whats a good CCA (Cold Cranking Amps) rating for a 92 LS with added bells and whistles (aftermarket radio, fogs, system, HIDs, 2 big subs, 1500 watt amp). My CCA rating is now like 500. When I went to test my battery today, it was good (Duralast), but the people in the store laughed at me. My brother had a Cadillac Seville or something and his battery had a CCA rating almost twice that, like a 920 or something. . . I know the Legend LS comes with lots and lots of electronic goodies and it's about the same length as a cadillac, but i'm not sure if I should stay with my battery size or not.
