Re: Wanted, ANY pics of flash boots :)
It's a big capacitor. It basically stores power and has a very little internal resistance, which means whenever there is a drop in voltage due to a big power draw (ie bass), the capacitor can deliver a large amount of power for that second that the bass hits, therefore keeping your voltage more even and ensuring more power is gained form the amp. They can discharge large amounts of power quickly but only for a second or so as they do not store alot of juice. In comparison, your average drycell battery is about 1000x larger in capacity, but has a high internal resistance and therefore cannot discharge the power quickly enough to keep the voltage steady. The number on the cap (short for capacitor) is the farad or amount of power it stores, the higher the farad, the more power the cap stores. It is recommended to have 1 farad for every 1000wrms of power you draw, mine is 1.5farad. Capacitors are more of a quick bandaid fix for a poor electrical system. Get your electrical system upto scratch (ie decent battery, larger alternator, thicker wires, proper grounding points etc) and the need for a cap will diminish quickly.
