i just found out powermaster makes a dual alternator bracket for my car that will bolt right up with my old stock alt. i currently have a 240 amp irragi alt and my other stock one is 115 amps.
i want to run a total of 6400 rms. i plan on running two 3k monoblocks and a 400 watt 2 channel amp. if i buy the bracket i will have a total of 355 amps available with my irragi and stock one. i can also buy a stock 200 amp alt thats pretty cheap, its about $130 so that will give me 440 amps if i go that route.
would it be better to just use the irragi 240 and instead of spending money on the dual alt bracket get some batteries? will an extra 2 deka 9a31s be equivalent to a another 115 or 200 amp alternator?
if i buy the bracket could i get away with just another small battery in the trunk or upgrading my stock battery up front to a deka 9a31?
