Thank you all so much for all of this help! I know it's really confusing to do through photos. You all know what you're talking about though!
We got the receiver that everettT suggested and the connectors that Latent suggested. Bought some speaker wire from Amazon but ran out half way through so I have more on order. The cord on top is to plug in a phone. The receiver isn't blu tooth but I think this will do. We used all of your suggestions and here's what we have so far. I am labeling every little thing! All of it is working!
