[QUOTE="hispls, post: 8816254, member: 614752"] What "problem" are you trying to get the capacitor to solve? As far as I know, even the lowest cost amps these days have enough R&D behind them that the power supply would have adequate capacitance built in, and capacitors aren't really a great way to store a lot of reserve energy. Energy is 1/2 the capacitance times the voltage squared. 1 watt is 1 joule per second. Figure out how much energy you're attempting to provide and you the calculator built in to whatever device you're posting this from should be able to give you an idea of what sort of capacitor bank you would need. Do take into account how quickly you will be able to recharge the capacitors as well. By my math, a 500f bank would store enough energy to feed a 1000W amp for a few seconds. That size Maxwell bank sells for around 350$. I suspect 350$ worth of battery would hold a bit more energy reserve but do what you like. The whole thing seems rather impractical for most situations, particularly with the current state of lithium options. [/QUOTE]
