raytard Posted March 8, 2009 Report Share Posted March 8, 2009 1 farad=72 watt seconds once a cap is drained, it doesn't recharge until the draw is brought down to a level where a reserve is created, its obvious that you cant start to charge something until there is current available, so if the amp draws more than the alt can provide, it drains the cap fiirst, and then the battery 72 watt seconds@12 volts...so thats like 6amps for a second...if you have 600 watts, call it a 60 amp draw, you get .1second of current from the cap, the rest just comes from thee batt and alt and the capacitor is just sitting there until the bass stops, then it recharges. a friend of mine ran 20 of those rockford hybrid 40f caps...so 800 farads. with 4 zx2500's. The caps were drained after a 3 second tone. get batteries, caps are beyond useless Quote Build: http://www.stevemeadedesigns.com/board/ind...hl=avalon+build monster/rockford/kicker/stinger cables, pioneer source, jbl highs/amps, kinetik/shuriken batts, iraggi alt, dei security, dc subs(atleast for now) Team DC Link to comment Share on other sites More sharing options...
The enD Posted March 8, 2009 Report Share Posted March 8, 2009 (edited) 72 watt seconds@12 volts...so thats like 6amps for a second...if you have 600 watts, call it a 60 amp draw, you get .1second of current from the cap, the rest just comes from thee batt and alt and the capacitor is just sitting there until the bass stops, then it recharges. If you have 40f cap i calculated that it is 2880watts per sec @ 14.4 = 200 amps for sec. What I got wrong ? 1000 watts music needs [email protected] = 70 amps and the cab can provide 200 amps ? There is something wrong ? Edit : I saw that 40f caps are 20 count x 2f ... and one is 278$... so there is no point of buying.
