200 Amp Alternator?

[BottleFedGTS]

I need a new alternator. I have underdrives, and a single 600 watt amp stereo in my car.... Is it worth it to go to a 200 amp alternator, or should i just step up to a 160? the stock 130 just doesn't seem like it would be enuf with the underdrives.....

i have a stock alt in my car (like 70amps i think?) my big stereo, whipers, heat, lights all work good

I'd think you'd be pretty safe with a stock 130 amp unless you have added a lot of accessories such as an electric fan, higher wattage bulbs.. plus your stereo system than and upgrade to 160 would be ideal. 200 seems a bit of an overkill at this point. I've never had problems with stock alternators, but I don't succumb to idling driving or stop and go traffic. I get in and hit highway speed 90% time.

My car does have electric fans.... stock i'm sure, i think that was the reason for the stock 130 amp

Take off your underdrive alt pulley.

Good call. Sometimes the simplest idea may be the best, huh?

You got it!

130 amp alternator is more than enough for all but the most rediculously ghetto stereo systems. I power a huge electric fan, some rediculously high wattage headlights, A/C, and an inverter for the laptop plus the stereo and she never drops below 14 volts.
