okay I now have the following.

punch 400.4
punch 300x
punch 800.2

i have two 1 farad caps. the 800.2 amp has extra terminals for a cap.
my question is...should i wire both caps into the amp in those terminals or should i just wire them insinc with the amps?
if 1 farad actually helps 1000w then would it mess anything up having them both wired into that one amp?
I just want to make sure i use them correctly and wisely

 

you can wire multple caps into that one amp.

 

would you wire them in series or parallel?

 

I wired 2 1 farad caps in parallel for my brother's set up. No problems at all....

 

capacitors add in parallel like resistors in series.
C + C
capacitors divide in series like resistors in parallel.
(1/(1/C + 1/C))

 

whoa you just lost me?

 

like this.
if you have two capacitors in parallel, they add like resistors in series. so
1F + 1F = 2F

if you have two capacitors in series, they add like resistors in parallel, so

(1/(1/1F + 1/1F))
(1/1/2F)
C=1/2F

 

oh ok i got ya. thanks. parallel is the way to go then.
