Is there a reason you want a capacitor as opposed to a decent gell / dry cell battery?
probably cos im running 3 amps in my car :)
Really? We regularly run systems here that utilise up to twelve amplifiers and we've not needed a cap yet.Quote:

old rule of thumb back in our hay day Marty was a 1 farad cap per 1000wrms, i still remember that :)
I have a soundstream capacitor in my car...
I can't really compare it to anything else as I haven't had anyother one before...
But remember with bigger or extra batteries comes the need for a bigger alternator. You have to be able to charge those batteries. Just adding one battery isn't so bad but when you add 3+ you have to beef up the alternator or it will take forever to charge up. If the alternator only puts out 130 amps at 2500RPMs+ and you have 4 batteries @ 2000 amps (500 amps each) then it will take at least 15 hours to fully charge. This is where the external charger helps. Also remember that when driving you use about 50% of the alternators output to run the car so the battery only sees 60 amps, if that, depends on the efficiency of the alternator too. Caps however are a great way for a daily driver to have a lot of power with out the added expense of batteries, alternators, and wiring. 1 cap per 1000 watts is still the rule of thumb but only up to 4000 watts, then you need batteries. If you have dimming issues while driving then the electrical system is underpowered and needs to be checked and fixed.
As for which cap is best, that is up to you since there aren't too many manufactures. The caps are almost all the same so if you want a $50USD cap it's going to be close, if not the same, to a $75USD cap. The differences are if it has a digital voltage led on it, extra connections for daisy chaining round or square, 1 farad vs. 2+, and colors. Get design you want then get the middle priced one. The cheap ones seem to fall apart. The expensive ones seem to be too much, but the middle ones are just right for most people.
fhrx: thanks for the smart arse comment, lol
slow96gsr: thats more what i was looking for
not all cap are the same, their is different material used to built them (some with fancy light, design but actually crap material), One of the best cap is alumapro, once design for nasa and military, now design for car audio with the same technology, i believe they are one of the quickest charging cap. Google it you'll find more info on alumapro
they come in 5,15,50 farad
as for the rule of thumb 1farad/1000watt i heard many say it doesnt apply for example a system putting out 1000watts, he uses 1farad, he claim didnt do much but when he try 5 farad there is a different.
you'd be surprised as to how many caps actually come out of the same factory and are badged differently for different customers :)
so unless you have proof you cant make those claims you know :p
I doubt that's smartarse comment; he knows he stuffQuote:

DSNTGR8, you've lost me. What are you talking about? I was being serious and trying to help you out.
