I've been told that if u want let's say 4000w of power, u need that much power in alts to supply it.
I understand that or do I? Why do others here, like Meade have only 2 300A but am pretty sure he is drawing way more than 600A with all those amps back there without any problems?
Another thing, I still run stock lead acid battery but have a 200A alt installed. I have metered my maximum current draw right now at 74A for stereo system plus whatever car uses. My lights dim pretty good on idle(idle output is like 55A) but when i go to rev it up, it helps but dont eliminate it. It will dim the lights only on a "punch" bass note. IF the bass is constant, it wont dim lights, only when it needs a quick burp of bass does it dim for a split second. Is that normal or what would cause that based on my setup?
I'm trying to figure out why other people on here are getting away with drawing WAY more power than what their alts can do but have enough batteries to keep the voltage sky high for long periods of time. I've been told this will kill the alt(s) fast but others do it all the time?!?! What's goin on?

The amount of time he draws over 600 amps is very short. The batteries supply the excess current. The batteries are just a buffer, not a major supply of current.

Your dimming at idle because the low output at idle you have. Reving the motor will help your lights but no matter what you do, you will have a little flickering in your lights. The punchy bass notes happen so fast that the regulator doesnt react fast enough and you will see a little flicker.....not to be confused with dimming. Dimming is when your voltage drops and stays there for a few seconds or until the long drawn out bass note is gone. Flickering is the time it takes for the regulator to compensate for the added current draw. If the current draw is very little, you probably wont get any flickering. Its kinda like when someone throws you something heavy and when you catch it, it drops a litle. If its light, it stops as soon as it hits your hands.
IF the bass is constant, it wont dim lights,
You may be down to 12 volts and not noticing the change in voltage. When the voltage drops, it stays there and you wont notice the lights going crazy. Most of the time, your headlights have the lowest volage of any accessory in your car. Its possible to have over a volt drop on your lights but not have any at the alternator.

Hope this helps. Dominick
