Default High Output Alternator for 2011 1500 Hemi?

I am in the middle of installing a pair of 1100w rms amps (60x2 fuses for each) to power two sa-12 subs and a 800w rms amp (40x3 fuses) to power (4) 6x9 jbl gto938 in my 2011 Dodge 1500 Hemi.

I am sure the 160 amp alternator won't cut it after installing the above, so I have been looking at upgrading to a high output alternator from either DC Power or Mechman. I spoke to Mechman and they discontinued the 270a version because it supposedly sucked at idle rpms. They now only offer a 240 amp or 320 amp.

Does anyone have any feedback as to either of these manufacturers or have another manufacturer they can recommend?
Thanks.

the stock alternator is 160 AMP
the Special Service Ram (police) has a 220 AMP
it runs a variety of lighting, siren, computer, modem, radar or camera systems.

so that 240 AMP should be fine
you may want to get a battery with 700+ cold cranking amps, new Rams have a 730 CCA battery
