How many amps is ur alt rated at?

 
your factory alternator is designed to charge your battery and then run the car's electricals. more than likely after that, there's not a whole lot additional left for the stereo system. that being said just because the your stereo system pulls more than your alternator is capable of providing doesn't automatically mean you need an upgrade. the battery acts as a buffer when the alternator's capacity is exceeded. how much wattage you have, what music you play, and how loud and often you play will all determine if a stock electrical will hold up or not. its gonna be different for each person and each car.

 
I have a 90 amp. F&f 65 ah bat up front. Big 3, stinger spv69 in back. Have 2500 watts to sub, 500 to comps. Sit at 13,7-14,1 iddle and up to 50% volume, down to 12.9-12.8 at full tilt... But full tilt iswith comps amp off.
