Capacitors

[Iskavan]

lets say i have a 3,000 watt rms amplifier, and i get a 20 farad capacitor. I know they do not add power, but they discharge quickly, in theory making the power to the amp more immediate, the alternator doesnt fight as much. Now because 3 farads would be 3,000 watts. Would the 20 farad capacitor be able to discharge multiple times, making it actually usually for storing electricity as well? Like a quick delivery battery.

I am not saying to replace a good battery, i am asking if its actually useful, and be somewhat of a benefit to have a high farad capacitor, to deliver power more cleanly/consistently.

It wouldn't last more than a second. That's why they are pointless

So even doubling or tripling the farads it still only lasts a few moments?

Yes until you get in the hundreds like maxwell ultra caps

The only capacitors I would get for car audio are Maxwells. I'm guessing that "20 farrad" cap you speak of is not maxwell

In a car audio application dose the Maxwel ultra cap stabilize the voltage but not reduce the need for additional alternator and batteries

Lots of people run just caps with their alternators, no extra batteries for their system.

Run just maxwell caps? how? do they keep a charge like regular batteries? what is the lifeplan on them? How many would you need for a 3,000-4,000rms system.

The new ultracaps most certainly work. 5 of the 2800 Farad caps would be enough as long as your alternator can keep up with 80% of the Load under a sinewave load it will be fine for music..

I'm doing ultracaps in my system, you really can't compare them to the old car audio capacitors that most think of. These things will probably replace batteries completely at some point.

Id love to know more about them and electrical in general. Its the area im rather rough in knowledge
