I'm confuse about the big 3 thing. I've asked question about it before but I'm confused. I'm only push 500 watts rms, but I recently killed a factory car battery and got a new factory battery for free. But do I need to just do the big 3, upgrade my battery, upgrade my alternator? I don't know what needs to be done. I drive a 2007 Kia Optima
