if its reading 12v, its charged. the reason for initial slow charge is to avoid sparks that can be big enough to blow off pieces of the connecting terminals of the cap.

I am getting a full system all at once. I will have an 850 watt amp for my subs, and an amp pushing a total of 300 watts to my speakers. Will a 2 farad cap be enough to handle them both? If anyone knows the equation to figure out the best size of cap. can you post it so I could use it?

a general rule of thumb is 1 farad per 1,000 watts rms total of the amps. There are exceptions but thats pretty much the rule. Your system will be 1,150 watts rms total so if I were you I would look for at least a 1.5 farad cap.

I am runnin the Memphis Mojo at 2000 watts, no need for me to daisy chain 2 batts to get the 2400, so do I need 2 or 3 farad?
