Well I am pretty sure my battery is done for. I am, or rather will be runing 2 kenwood 12" subs, 4ohms, 600w max, powered byt a rockford fosgate 250m power amp, and a eclipse cd3402 deck runing fosagte speakers, 6.5 (75w rms, 150w max)up front, 5.25 (60w rms, 120w max)in back. also i have a 400w power inverter that will be powering a 13" tv, and a playstation/n64/vcr (one at a time) probably for extend time without car on. anyways my question is this. If the battery has to be replaced, is it worth it to get a nicer battery, as in would it help/make a differnece at all, and is it worth the money.
