Ok

I’m back on site. I used an impedance meter to get a couple of readings.
There’s two legs that come into where the speaker is connected to the amplifiers

The first leg is at about 180 which is the ground floor and the second leg is at about 30 which is the second and third floor

When I tied those legs together, it’s still measured the same as the leg on the second and third floor 30

The impedance meter is at 1X

I also just hooked up one 5W ceiling speaker at 1.25 Watts to the back of the amplifier

I was using my iPhone and input seven or eight I had the master volume up at halfway and I had input seven or eight up at halfway and I could barely hear anything coming out of the speaker

When I raise the master volume I think was almost all the way up and then input eight or seven I could increment those, and it would get louder

Does that sound like there could be something wrong with the amplifier
