Am I doing the calculation right???
4 speakers x 100w = 400w; 2 sub @ 1200W( Sony, 10") =2400w
would require 3.0 to 4.0 farad cap; divided into two = 2 x 2.0 farad

ok, thanks for all suggestions. My mono amp is 300 amp from JBL feeding two 10" x 1200W Sony subs. will 1.25 farad cap be satisfactory, not blowing anything in the system???

0.5 Farad for every 500 watts, so for 2800 watts is 3 Farad.

You don't want to calculate the speaker/sub wattage ratings. The power ratitings on speakers and subs is just a maximum input, that is not the output rating. Use the RMS rating of the amplifier at the impenance configuration you have. Ex,..125 watts x 2 rms @ 4 ohms = 250 watts use a .25 farad cap. 250 watts x 2 RMS @ 2 ohms, use a .5 farad cap. 1Farad for every 1000 watts of amplifier power.

the math is 1 farad for every 1000w of amps so 1 3farat cap would work fine.

a capacitor stores a small amount of energy.they are not required.but recommended on a big stereo system.a cap keeps your system from directly draining the battery(causing lights to dim when the system hits).a fared is = to 1000w.
i have 2 memphis 12s on a 1500w cerwin vega with a 1 fared cap,and my mids & hi's on a .5f cap
