Well, ish, a simulation of one xD
≈199A output, maximum load of ≈2kW with output voltage stable at ≈14.3VDC
1F capacitor because this is going to be used for an audio system so we want to ground ALL AC noise that could possibly be generated
This has a 9 diode output bridge, utilizing a full 360° signal at 40° intervals, so this is a pretty heavy duty alternator and should be able to handle your load happily
