Where do I connect the wires to the circuit board?
Where does ground go? Where does left and right go? (on the circuit board and on the jacks)

Did you even read this thread?

I posted pictures just a few posts back.

So if i put my  prosound 1/8" on either pot or post, i have to put the RCA on the other?

Nope. you can connect 120 prosounds at post an pre pot. whatever you want. It's just advised to not use more then one at the same time.

I never put a ground on mine, I do internal prosound using the stock jack. Should I be grounding it?

Then you're probably just using 2 wires, which are the "left" and "right". The stock jack is already grounded, so there's no need to do anything else, I suppose.

Max Volume Baby! yeah!

So your saying that it would just put it to the highest setting of the volume slider? So if i put my  prosound 1/8" on either pot or post, i have to put the RCA on the other?

You need at least 3 hook up wires right? Whats post and pre pot? Does it matter if i have a prosound mod already installed?

You can install as many pro-sounds as you want. I wouldn't use them all at the same time tho.
you could install RCA and jackplug in one gameboy for example.

and post and pre pot is just as it says. before or after the volume pot.

if you install post pot, you can use the volume slider to control the prosound. see the pic i posted a few posts above.

What happens if it inst hooked up to the volume slider?
