    funny thing is, some people actually believe everything they read....... well read this: THIS IS NOT TRUE!!!!

    from an earlier post in this thread:

    the best solution is a combination of an aux battery close to the amps & a stiffening cap. A configuration like this will allow you to draw up to & even over your alternators output for short periods of time without a problem....

    as far as idle drain,depending on the cap design, it can draw anything from a real small amount of current(.01-.02ma) up to enough to kill your battery in a several days. the best way to install a cap(s) is with a high current relay that disengages it from the battery while idle(parked). most carbon based caps are installed that way manditorily, as they will draw up to & over .06ma wich is enough to kill a battery overnight ...

    a quote of a quote..... from a toyota forum..... see, that's what I mean, you read it so it must be true.... believe what you want..... I believe what I said & I've done more than my share of big systems ... not read about them......

    have you ever heard of the term "bench racing", well were doing the vertual equivalent of that with car audio right here....but in the end it's real world results that count

    a cap will not hold an extra output for an extended period of time.... it is very possible to have a bass drone outlive the usefullness of its current charge, but that's not the point..... a car can still bottom out with shock absorbers, does that mean you'd rather not have them?

    are caps over rated & miss-used? definately, but they are far from useless...

    We do not know eachother personally, so let's not make any assumptions as to eachother's credentials. I disagree with how caps are generally used in car audio. There is a wealth of mis-information to be found all over the internet. I go by personal experience from various systems I have put together and or seen in person. I have seen caps work, and not work at all for the problem of dimming. I always prefer to use the methods that always work, rather than rolling the dice with a device that isn't always the answer. Know exactly how it works is a big help.

    you said "... caps are completely useless, don't buy them"

    ...not that you disagree with how caps are generaly used....., as your now saying

    the only assumption I made was that you are completely wrong, & I assumed you read this somewhere, which you then showed me where you read it

    BTW, the dimming headlights are not the real actual problem, they are a result of the problem & a side effect of the problem...

    The Cold Hard Truth About Caps

    For starters, a large mistake everyone makes is how much power they are running. For instence a cars electrical system is measured in amps or ampere which is a measurement of electric current. This means, its NOT HOW MANY WATTS! a good way to get an idea of how many amps your amplifier draws is to look at what size fuses it takes. For example, my kicker kx600.1 Amp has one 30 amp fuse. Therefore, the amplifeir cannot draw more than 30 amps or recieve more then 30 amps. Typically they will match a fuse with an amplifer giving it around 3-5 amps of room to go over. This would mean that my kicker amplifier takes 25-27 amps but has a 30 amp fuse. A typical car's alternator is capable of generating 150-180 amps, but dont forget it has to power your entire cars electrical system (lights, windshield wipers, fans, cigeratte lighter, stereo, etc) and charge your battery simultaniously.

    Now to my next point
    a capacitor is a device that stores a short instant electrical charge. When your amplifers are running for every output of sound like a subwoofer for instence, they require a tremedous amount of electricity. Your battery has an instant 600 amp output. plenty of power to power that amplifier. Unfortunatly every time your battery discharges your alternator has to recharge it. Now if i add an capacitor in the power line it adds an additional source of extra power at the cost of losing my alternator down the line. This is due to after the capacitor discharging along with my battery the alternator has to work twice as hard to recharge both the battery and the capacitor. So in lamen turms, a capacitor is a band-aid to a bigger problem.

    How to get more power!
    why not instead of wasting one to several hundreds of dollars on a short term solution such as a capacitor you could just as easily go to an automotive shop and have your alternator replaced with a high performance one or simply get your old one rewound, but what good does plenty of power due when theres no where to store it? you wont necessarily need a performance battery but a good one. this will help by backing up that high charge. everyone with a cap will eventually run into the problem of destroying there alternator costing them more in the long run. so this is your chance to get it right the first time!

    Damn, now I'm confused. Turbocad said that having a cap will prolong your alternator:

    the stiffening cap will actually prolong the life of your alternator in the same way, by "absorbing" the big instantanious demands for high current & smoothing them out to a certain point.
    Now you're saying it could actually cause the alternator problems faster due to the extra stress of charging both the battery and the cap. I'm so fkn confused. I'm glad I don't have money to waste on stupid audio stuff like this.

    Just kidding, I do like your explanation/reasoning muscanto. It definately sounds like a reasonable explaination

    no way ... his explanation is wrong. Capacitor is useful part of Car-audio installation in many cases ( no in every, but in many).

    here is explanation that is right
