Can my car handle it?

If I run 3 Kicker S12L7's at 500 watts RMS or more each(totaling 1500 RMS or more), will I need to get a second battery and/or a high-performance alternator, or will my stock battery and alternator be ok? I have a 1996 Buick Regal.

I also have a 1-farad and a 1/2 farad Rockford Fosgate cap attached to the system

get a better battery

Do you mean replace the one I have or get a second one to power the system alone? Any suggestions on brands or types of batteries, and what's the price range?

replace, optima yellow top

hay what kind of yellow top like what moddle should i get, i have the same problem, i have a ford mustang.

just go to the local car shop, like autozone and grab an optima yellow top
