    Icon32 Would I need to upgrade battery, alternator, and/or do the big 3 upgrade for my setup

    I have a 2008 Pontiac Grand Prix Base model with the V6 engine and stock alternator output is 125amps. At max I would be running about 800-900 watts RMS. I want to know if I should upgrade any part of my electrical system to handle the aftermarket car audio setup. I was thinking about getting a good odyssey battery and maybe upgrading the big 3 or if possible not get a battery and just do the big 3 upgrade with 0 gauge wiring. Don't want to upgrade to a HO alternator if I don't have to considering how expensive they can get.
