power Capacitor help

I'm looking into buying a Power Capacitor for my sound system but im not sure how the whole farad thing works. i have a 1750 watt system. what should i get in terms of the farad numbering system like, 1.6, 2.0, 3.0, etc.... i can't find like a chart that breaks down how much the different levels put out.

caps will not help you have more bass. Look up the big 3, it will do more for you.

im not asking about increasing my bass. im just asking how much watts the farad 1.7 etc. support

the old formula was 1 F for every 1000 watts
