first, I don't know my budget yet, I'm only speculating.
I will most likely add a second 120 amp alt.
I CAN run only one battery, the setup my brother did was 149.9db with a wal-mart battery, 90amp alt and a 50 farad cap. no dimming lights and no major voltage drops.
I didn't fall out of the thread, I had to take my mother to a doctors appointment, life is more important than a bunch of haters on a forum.
and I do want to compete, Im just not driving 400+ miles to go to a comp. learn to read what I say and not what you think I said..
and I never said I know everything, but what I do know is if my brother can do 2000RMS to his subs with a 90 amp alt and 1 battery then I can sure as hell do 3000RMS to my subs with 240amp between two alts and a single battery.
