What Size Alternator

[snyper99]

i looked around trying to figure out howw big of an alternator i will need but i couldnt really find anything specific,so here i am asking for an answer.any help will be greatly appreciated.the car is a 99 grand prix,the stock alternator is 110 amp and i have also done the big 3 and the lights still dim a fair amount.

heres my setup

2-12"alpine r-type 1242d 1,500w peak/500w rms

2-6x9 infinity 693.7i 300w peak/2-110w rms

2-5.25 polk audio db5250 2000w peak/10-100w rms

1-profile ap1040:

80w rms x 4@4 ohms

125w rms x 4@2 ohms

disregard this crunch amp

1-crunch gp1100 (i think):

275W x 2-Ch @ 4-Ohms or

550W x 2-Ch @ 2-Ohms or

1100W x 1-Ch @ 4-Ohms Dynamic Music Watts

im replacing it with a HIFONICS BXi2006D and i will be runnuing at 1ohm

A 200A alt will do you good, with a big batttery under the hood and in the back...
