I recently purchased 2 fi btl 18's all options except heat ring. I have 1 rf t 4000. Using all Kicker 1/0 wiring. 2 optima yellow tops and 1 kinetics 1400. I am going to put them in my 2006 infiniti g35 coupe. I ordered a iraggi 200 amp alternator 2 days ago is it going to big enough to keep the batteries charged or should I leave them on a charger at night??? Is there any risks to the car of upgrading the alternator???
