actually i found the needed drivers and amps. but i don't know ANYTHING about capacitors... i've got - 2 [800W rms]GTX 12dB Warrior III(12")- wich i plan on to hook up in parallel with a 1750W rms 4ohm amp... can i use a single capacitor? or do i need one for each sub? and how many Farad should i use? is 1 way too much/ way too low?
