why would he need a high out put alt?....
i had a audioque 2200 at .5 ohms with 1 stock battery and 2 dekas and never saw below 13.1
i clamped the audioque at 2850 at 1 ohm so im sure it did more at .5 ohm
car was a 07 honda civic
not saying that you all are wrong, im just wondering.. because ive never had a issue now my next set up will need a alt i know forsure but i dont think 3k rms would
