My alternator is a stock alternator, 90amps I believe. Would this be enough to run two kappa perfects 12" with an Infinity 1520a running it as a 4ohm load of 850watts? i would really try to avoid getting a new alternator, but if i must...i will. what are the reprocusions of not getting a new one and using the old one? thanks for the help guys. you all are teaching me a lot.
no, a capacitor won't solve a lack of power problem, only an alternator will. a capacitor just provides power really quickly and at a slightly higher voltage making your amp respond quicker and put out a lil more power.
i only had a 75 amp alternator and was pulling around 60 amps with my 2 amps and i didn't have any problems. i've since upgraded my system and alternator.
