Will it be enough

[99fullsizechevy]

Tripple Alts, one stock one rebuild/upgraded stock alt, and a 240 dc power pro... Then two o'rileys brand 78 series agms under the hood with either one Redtop or two xs d680s in the cab..

Running an aq1200d, want it at .5 ohm till January when my second 1200 gets ordered then they will both be at 1ohm or 2 strapped along with a 4ch for doors and a 2ch for rear 6 x9s

My question is will that be enough to run that amp at .5? And enough to power all 4 amps?

200 amps at idle after the truck and accessories are taken in account... Aprox 450-500 amps total while driving

Total current being used at full tilt would probably be around 320 so thats 120 amps short of what I got at idle, is that enough power and battery reserve to hold out for demos and such?

man that will be more than enough. in my daily im running 5k watts at .5ohms plus 2, 4 channel amps all on stock electrical and 2 batteries no issues and not a fling of dimming.
