That was not helpful. How is a dozer going to help? The moderator replied that a Cat D6 is what I need.
The dozer would be used to dispose of the consumer garbage you wasted your church's money on.
Without being here day in and day out those of us that support the critical role audio plays in worship break just a little bit inside every time a post like this comes up.
We know you thought you were doing the right thing but what you did was waste money.
Why don't you ask before you purchase? That's a low end home receiver, it is not designed for what you are trying to do. You would be hard pressed to find speakers of less quality than the Pyle's. If you get more than a few years out of them you are lucky.
Most important they are the wrong speakers.
Can you return the equipment?
The advice you received is spot on, at best you need to purchase transformers to couple all of those speakers together. You also need the correct volume control. The speaker selector you bought is useless. The receiver can't drive more than two speakers at a time per output. There are other limitations that prevent you from using the receiver. While it has many channels they are designed to reproduce multi-channel effects, not drive concurrent loads. You can't even break it up into zones.
