[QUOTE="Buck, post: 8747139, member: 591582"] I agree with supercaps being useful. Really it all comes down to how you set your system up. The super caps can help on the extreme end of the system. You have to remember to that not everyone is playing the same thing with their system, and that can make a huge difference with electrical. Some people are playing in the 10's and 20's hz region, and that's a whole different ball game than burping at 70 hz. Just having alts and AGM's can make a system work well. Having alts and lithium can work well. Having little alt and lithium actually seems to work well, surprisingly well, from what people have told me. I really think alts and lithium and super caps is just next level. You just line up the charge/discharge rate towards the amps: alt (slowest to react) -> batteries (depends on discharge) -> caps (almost certainly faster than anything else) -> amps. So what you're doing is creating a multi-level electrical dampening system, where in stages each component can feed the caps, essentially, which feeds the amps. That amp will get exactly what it wants, because the caps can always charge off the lithium, and the alts will charge the lithium however much it's needed. Those caps should technically help with initial voltage drops, due to any change in frequency or volume. Caps also might be a good noise filter, in a way. They might help clean the power up, so might the battery as well. That may possibly be another reason to do that, is prevent any kind of noise, because the alts ultimately produce the power in AC current. The batteries and caps I think would probably help filter out any alt noise that makes it in 12v form, or whatever. The alt is pulsing it's 12v power at a certain frequency (because it's spinning), where the DC batteries and caps aren't pulsing the 12v, it's constant, which means the amps aren't getting as much pulsed 12v into the power wire.
