I was reading in some thread recently about some guy talking about capacitor banks being the tits. Saying they could supply power for 5 seconds and gain deebeez on burps over batteries and are better because they charge so much faster. Is he trolling, talking out his ***, or am I just missing something?

This what you mean? Capacitors are cool

I'd say that's not bad advice. If you don't like your lights dimming get LED headlights. If your voltage is dropping to a point where you will hurt your amp(s) then you need to probably do something else.


Google can provide all the formulas you need to figure out how much energy can be stored in a capacitor. At some point a large enough bank of capacitors might help, but I don't think anyone is doing enough to make a difference. Simple enough test is to turn everything on at even moderate listening levels and disconnect the battery and see how long that capacitor keeps everything running before it powers down.

You're missing the point of capacitors, it's not about total reserve capacity it's about discharge rate. Batteries can store a lot of power but they are quite slow to discharge it when demanded, caps can fill that gap if used appropriately.

Also as it's been said, the 'banks' of caps that people build are not the same thing as those crappy car audio capacitors they sell in the big box stores, they use actual industrial capacitors and by building a bank they can achieve a much greater capacitance.

Riiiight. So having a great "discharge rate" but only enough power for half a second helps a bunch if you need 3 seconds worth of current draw? What's the difference between the "crappy" capacitors and the special ones that makes them do something different?

I didn't say anything about their applications and helping with 'burps' all I said was your 'simple test' was fundamentally flawed.

Maybe they should change the name to Cemetery.

Capacitors discharge and re charage and whats called a Tau= (Resistance)x(Capacitence) and it only discharges or recharges in 1 Tau at a time, to full discharge or recharge it takes 5 Tau's so to say this discharge "faster" is correct because there do not have the same capacitance as a battery per say0.

Just took a test on this capacitors, so nice try.

So what is your point then, that if they don't have enough energy to supply a 3 second burp they'll be better for music? Go buy a bunch of capacitors, I'm sure it'll help you somehow.

Are you really that fuggin clueless???? What are brocks, hall, and fish using to set world records in BURP cars....
