vn commodore alternator upgrade

[ti09ny]

Hi I'm buying a 250 amp alternator for my commodore from the states.... It's for a Buick Rivera with a 3.8L v6.... I know it's gonna fit the only promblem is my commodore has a 2 pin regulator and the Buick has a 4 pin.... Is there a way to wire it up to work for a 2 pin

Why do you need a bigger alternator?

u should b able 2 get the same alternator with a 2 pin connector so id say uve got the wrong alternator.

[Crewmanss 06]

yep as said above you have the wrong alternator

ah ok i just need to locate an alternator rated at 250 amps for my sound system.... got any ideas or websites for me to get 1?

[wrx884]

how bigs ur system coz u should b fine with just an 85amp 1.

99% of professional stereo installs don't have a bigger alternator. You will be fine with the stock one.

your going to have to have your car revving its tits off to be able to get it to charge that high. ever noticed how much the revs drop with the stock one when you load it up? and its only prob putting out 20-30amps.

and most yank cars have a different regulator. lots of them don't run warning lights etc, and have a 4 pin denso reg.

Yeah some how I doubt it.

.

not really depends how small the pully is on the alternator and where the charge rate line is 4 it 2 start charging.

tho saying that the smaller the pully u put on it the more ud likely 2 wear out the bearings faster.

mtx jackhammer sub is 16,000watts so its do able. im after one to upgrade from stock as im going to be running two amps

alternator from a statesman or calais 85amp is good ... 140 amp from VPW is good also but prob with the bigger amp alternator is some dont put out 13-14v on idle only @2000 rpm they start charging

Get 2 optima batteries one red top starting battery and a yellow top to go in the boot to power just the subs .... ( BTW i can get u a really good price on these batteries )

you need good batteries aswell as an alternator to charge them

Really? What is it?

I also don't believe you need the alternator. I used a stock alternator for my old 2800Wrms (or 56000Wmax ) stereo.

Bosch make a 120 amp alternator that is the same as the original commodore one (mounting holes line up, not sure bout regulator side of things though). Im planning to get one of these myself. A good idea would be to do the "big 3" as the stock charge wire and earths are absolute shyte
