Hey everyone. This is hopefully an easy question. I recently got a pachislo machine. The volume is too loud, as they tend to be, so I am installing a Potentiometer to use to control the volume going to the two speakers. Attached is a picture of the speakers. They have two wires going to each. One is clearly labeled as + and the other as -. I am using this potentiometer, so that I can wire up both speakers to the one pot. I found this page here. Which shows how to wire up the pot: So now I need to know how to use all this information to actually wire it together. Is the negative (-) wire coming from the speaker the ground wire? If so, is my attached wiring diagram correct how I have it set up? |

Your diagrams and wiring seem right on, based on what I did, but I don't know if you need any resistors inbetween. |

Post-amp, you need something like this..... http://www.radioshack.com/product/index.jsp?productId=3207537 You don't need one that heavy duty. There's a name for them, but I can't remember what it is. I have one in one of my parts bins....somewhere. It's been there for over 10 years. If I can find it, it's yours. *I know nothing compared to the electronics gurus of BYOAC. Hopefully they'll weigh in. |

alright, found my old one (used to control the volume on the center channel speaker of my car stereo back in the 90's). It's called an L-Pad. Do a search on fleabay for L-Pad. It might be just as cheap to get a new one on there, but my offer stands. Wiring is easy. speaker wire in...and speaker wire out. |

I don't have my pachislo near me but i believe they usually have a volume control hidden inside somewhere. I think it was just a button for low middle and high volume but don't quote me on that. I know I turned mine down before I gave it to my dad. check what everything does before you go and install sometyhing thats already there |
