How many Batteries
I am running 2 each Soundstream PXA 2000 d's @ 1 ohm and 1 eahc human riegn amp at 2 ohms I currently have a 175 amp 15.5 volt aletnator and 1/0 stinger power wire running from Optima Blue top groups size 31m battery a local dealer tried to sell me another Kenitic HC$ 2400 amp battery what do you experinced guys think ,do you guy's tghink I really need 2 each 2400amp hac kenitic amp batteries?Or will I be okay with one 24000 amp kenetic and the existing battery??

The 15.5 volt alt on 12 volt battery's kind of scares me.

But are you experiencing dimming lights real bad? have you put a DMM on your rear battery while it was jamming to see what it was dropping to?

More than enough electrical is never a bad idea in my book. Buying 1 more battery now is def cheaper than buying 1 more battery and 2 amps later (if you even need it of course)

no I have had no dimming of lights even during high bass transeints ,but this sales guy /installer was trying to get me to buy nother 24000 HCA kenitic battery as it stands now I am running 1 optima group 31 m 1125 amp battery under the hood and one kenitic hac 200 ampbattery in rear hatch space but the sales guy was trying to tellme to hit my maximum potential I needed one more hca 240 amp battery and just wondering if I really did and @ one tine we did check the voltage of the main battery lead under hod and @ peak I was down to 14.7 volts

if your only dropping to 14.7 then you don't need another battery.

although i'm surprised that electrical is holding up that strong against that much power.. assuming those amps are 2kw @ 1 ohm(never heard of that soundstream model)

thnaks I appreciate your input ,again these are y2006 pca2000ds classd mono amps sounsdtream under the old picasso series with a 2.5:1 power ratio I hVE THE BOX WITH DATE OF MANFACTURE AND s/n on

I remeber those amps but ant they were good . my question is you said you tested the fron battery and never whent bellow 14.7 but what did your rear batter read at when at full tilt

v6f150 04-13-2009 11:29 PM

have you done the big 3?

bassnut 04-13-2009 11:33 PM

not sur what you meanby the big 3 I was down to 14.4 @ rear batterry when peaking

Your best bet will probably be to run about 5+ farads of boost. Adding another battery only puts more strain on your alternator. If you were dropping below 14.3 volts, i would add another alternator and then run an additional battery. Your alt amps to battery amps ratio should be at least 1:5 or 20% or greater at idle.
