Yes I know however The rule of thumb is to put in 1 Farad of capacitance for every 1,000 watts RMS of total system power. But there is many capacitors that claim 1 Farad that wont make a difference if running over 600 watts So for one I had not seen that it was a 1 farad cap and I am unfamiliar with fosgate caps though I do like there subs and amps. Anyway thanks
