[QUOTE="n2audio, post: 8596471, member: 540940"] A 1F cap stores around 40J of usable energy in a 14v system. One J is one watt-second. 40w-sec in relation to a ~1000w amplifier is obviously, close to nothing -- considering a ~1000w sub amp will be generating several hundred watts instantaneously when the bass hits. Add to that the cap's internal resistance (ESR) and the losses in wiring, and it is actually very close to nothing. If you're using a big cap, they store more energy but generally have higher ESR (less efficient) and take longer to charge. Caps are used correctly when they're designed into the amp's power supply. Beyond that, they are a profit tool for audio retailers and not much more. [/QUOTE]
