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.
