Default Voltage concerns

<P><FONT style="BACKGROUND-COLOR: #f5f5ff">I have a 310a alt from ohiogenerator with 3 batteries... factory up front with 2 yellow tops in the back. System is a DD M3b pushing 2 15" mojo's on a factory head unit. Custom&nbsp;wiring harness is being put together so I can put in a double din bc I was told they dont make a harness for my car. Aslong as Im on the gas or moving Im good but at an idle it drops into the low 11s. Is this normal for what I have and do I just need to add another battery or upgrade the ones I have Also when I first start my car its around 14.2v but as it warms up it drops to around 12.5 and from reading other threads it seems its suppose to increase in voltage as it warms(chrages) not decrease? Is this true? Needing help!!!</FONT></P>

At idle its 200a.... So my voltage dropping as it warms is not normal I called and asked a guy from ohiogenorator and he told me the alt puts out power as needed so basically thats why its only 12.5 at idle when system is not on

motor is not spinning fast enough for the alt to produce power.. look for a smaller pulley..
every single high amp alternator ( espically something over 300a) needs more than 500 600rpm idle to make it work
when i had my mechman 320a on my g6 i dropped to resting voltage at stoplights n such ( car only idles at 500rpm)
i called mechman 3 times about it..and even they said its normal..i couldnt get a smaller pulley..already had the smallest one possible

so basically your alt dont put out anything at such low rpms and you rely on battery power.. which optimas ARE NOT really a good choice
