Amp Power
i want to but 2 amps, a 4000 watt amp and a 800 watt amp , with the 4000 watt amp i am purchasing a 1.0 farad capacitor, i was wondering how much power i would need to run this system? would the stock alternator do it? or would i need a more powerfull one like a ambulance alternator. Thanks
