Which HO alternator to get?

[dece870717]

My rockford fosgate power-1000 according to the sheet I got from the box uses 1500 watts RMS total and the sheet says it is 70% efficient. So about 104 amps of power at max. I have Kinetik 1800 as my starter battery. My stock alternator is 125 amps. I did the Big 3 but my lights still dim at high volume, but has improved. Should I get a 160 amp alternator or 200 amp? Don't want to spend more if I don't have to but I want to make sure I have enough power and alternator lasts.

Well I already know where to get the alternator but I just don't know which one to get, 160 amp or 200 amp? Ones I'm looking at is Bosch 160 amp and its $240, 200 amp is $320. If 160 amp is enough than I'd just get that and save myself some money. But if I need a 200 amp then I'll just get that.

what do they do at idle what kind of warranty the 320 prce might be as much as an alt that does 125+ at idle from dc..

for those prices id just end up getting a DC power alt, heard of them being some of if not the best HO alt. DB electric is cheaper, if you wanna go a cheaper route.
