Why you don't need a capacitor

[bazzle]

As I see it I would go for a dual or larger capacity output amps batt 1st, then a larger alt. Also depends on how long you continuously need to draw the higher loading for.

so i guess in reading this you would firstly go a bigger alternator then dual battery?

It realy depends on a few thing. Mainly how much current you need and how much you system is drawing without the system.

The first thing you should do is upgrade you Big 3, have good size cabling for you system and a decent battery. It doesnt have to be anything expensive. You should be able to run 500-1000watts.

For example, im using a battery intended for newer and larger european cars and i have upgraded my 70amp alt to a mk3 90amp alt with the option of going to a 120amp vr6 alt with ease. All this cost less than a capacitor.

Thats a real life situation.

If you are going to run more than 1000rms wats THEN you should concider larger alternators and performance batteries.

If we refer it to the lessons you should first try to drop the ESR by upgrading your cables. Then a higher output alternator because that is the first thing the system will draw current from. Once the system draw exceeds the current output of the alternator then it will draw current from the next highest point, which will be your battery. If your alt can produce enough current to suport your system than it wont feed from the battery.

LOL!
i tried to read this but halfway through i thought to myself WTF is going on.

i dont understand any of it. but if someone could put it in easy english for me to understand as i do run a capacitor in my car and im told it makes a difference. can someone help please :S

Based on my understanding (sorry I didn't read the long essay as I'm really bad with electronic terms and formula).

In layman terms, it makes a difference (only for that short instance) if your alternator is not able to supply the required current load (that's where your voltage will dip). What the cap supplies you is not sustainable if your alternator is not able to supply enough to charge it. The cause of the problem is the alternator, why do you need a cap for? Get a bigger alternator.

Your wasting your money, better off upgrading your battery and cables
