cap math?

alright, here's the deal, i've been doing simple stereo installs for myself and my friends for about 6 years now, i've learned a lot, and i feel i've come a long way, i've always gotten away w/o needing to use caps ... by using efficiant amps and matching the subs well .. well last year i ended up w/ some big equipment, and i've got it in my '00 blazer LT,

orion 2500D 2,500W RMS@1 Ohm driving a 1999 15" orion HCCA
orion 50 watts x 4 chan. @ 4 Ohms
200 watts x 4 chan. @ 2 Ohms
200 watts x 2 chan. @ 4 Ohms Bridged
driving 2 sets of memphis 15-MSYNC6 components
the sub hits hard [as it should w/ 2500 watts

but of COURSE the head lights "dim" ... now i know a cap isnt the "real" way out, i need a bigger altinator, [and prob a few caps] but for now i dont have the money to put in the kit Stinger [manufaturer of after market altinators] and local shops recomended

and this just isnt a good enviroment to put a car computer in.
for me another battery is not an option either for various reasons.

so i know this is getting long but .. the 2500D takes 2 4gauge power feeds, the 4004 takes a 4gauge input, i havent run the cabling to my pc yet b/c i need to get the power spikes undercontrol ... the QUESTION finally is would 3[one for each power line] 1or2 farad caps do the trick? [at least till i can pony up the 800+ for the altenators/install] - i know thing WAY bigger then this have been done, even here on this site []

thanks for the time reading this, i've gotten very mixed feelings on how to do this, hoping as a community i could get some good input here .. again thanks in advance!
