if your running your system without the engine running, then divide the rms by 12 to find amount of amps

if engine is running, divide rms by 14

duty cycle of music is such that even with 4000 rms, youd be fine with even a 90 amp alternator.

much less a 120 amp high output alternator
much less a 200 amp alternator

and if you dont mind light dimming, and your not cranking it to ungodly levels all teh time, yes, even a 70 amp alternator is fine. read teh post!

if you THINK you need a new alternator, you probably dont.
