How much headroom does the stock electrical system have?

So I added a small 8 inch subwoofer and an amp that is rated at about 250 watts. From the math I did, I figure I知 drawing about 25 amps max. I知 just curious how much strain that would be putting in the stock electrical system and how much headroom the stock alternator allows for. For example, say I have headlights on, the power inverter on at 100 watts, phones charging and subwoofer going, am I overloading the system with the additional current draw the subwoofer is imposing?

Hell no, I've been running a 250w amp in my last 2 4Runners both a 4th gen and 5th gen and never had any electrical draw issues or dimming lights.
