would a optima yellow top and a big 3 wiring upgrade on a stock 110 amp alt be enough to run a re12.1 and a amp for my comp's TBD later?

i would just run the amp on everythign how it is..
1200 watts = about 120 amps

and you wont be using all 1200 watts...

use what u have until your voltage drops at stoplights

yea. but when i throw in an amp for my componets in another month or so, and i have to have the power to run my car normally, plus, with just my HU and speakers no amps right now, my car usually only runs at about 13.4-13.8 volts and drops to like 13 at stoplights, so maybe i should just spend the small cash and upgrade the battery and big 3?

thats really strange for your car to be that low now w/out a big amp. w/ my 2 amps i'm at roughly 1100 watts rms and my voltage does not drop below 13 i just have a red top battery and 1.2 cap.

ya but blaine if it was 1200 watts that would be 10 volts going to it there will be more if it is the 14 volts it will be about 85 amps or so

but if what your saying matt at 13 it would be 92 amps
