The math gets complicated and there are too many unknown variables. The short version is this, the stock battery is good up to about 1,500w. After this, I would recommend immediately going to a two battery system or a single high quality AGM Battery like the XS D3400. If you go the single route and after installing your audio, your headlights dim drastically at idle, you are going to need a second battery and/or larger alternator.

Changing out the vehicles blood line may seem easy, but I recommend paying a professional to analyze your needs, goals and ultimately replace the alternator if needed. Whatever you do, do not fall for the capacitor scam and waste money buying that useless crap.
