Clipped said:if you plan to do alot of bumping at night, id get the alternator...
in my old ride i had 1900watts (2xorion250 hcca/1 x ppia600)
on a 70amp alt and 70 ah batt, and it was enough to keep up.
id run the big three, and install anothe positive from alt to batt, this should be done anyway and it may endup saving you money if the results are good.
ppia600 said:I believe the pcx2200 is 800wrns at full clip. Add the other two amps and that totals about 1200wrms. That will require ABOUT 130 amps at 12vdc if it is a constant draw. (class a/b amps, not that efficient) It will be cutting it close with that alternator considering you'll have the vehicle's ignition system running and maybe a/c and headlights. But if you don't run it full clip constantly (for more than a few minutes at a time, it will be okay. The battery will be a reservoir until you turn it down to a normal level.
