The house we bought has a single ceiling speaker in 5 different rooms throughout the house. They all appear to be connected and terminate at a single 2-wire feed in a first-floor closet. After experimenting, I found that an old 5.1 receiver I had lying around worked best if I hooked up those 2 wires to the +/- of the center channel of the receiver. It didn't sound great, but it worked. Unfortunately that receiver died recently and I need another (or new) solution. The music source is my Logitech Squeezebox Boom which I have 3.5mm aux out going to RCA cables on the other end They used to be plugged into the "CD" input on the receiver.

Can anyone suggest the best way to bridge the stereo source to work with my mono speakers, in addition to powering the speakers?

Thanks!

The system was probably wired to a high-voltage PA amplifier; a so-called 70-volt output is provided on those for that type of setup.

You need to read up on 70-volt amplifiers and PA systems.

Look up "constant-voltage amplifier systems".

Thanks for the response!

So something like this? I'm really just looking for a low-cost solution...

I'm not sure what ohm these speakers are - I'll have to take one down and find out. But once determined, both positive and negative leads go into the same ohm-labeled output?

You need to find out how they're actually connected first.
No, both wires don't go into the same hole. Use the common for one of them.
