I just had my outdoor covered patio wired for 4 in ceiling speakers to play sound off of a TV as well as music via a Sonos amp. I was looking at where they dropped the wires to connect to the amp and noticed only 2 sets of wires (black and white). When I went to look at the wiring outside I noticed the speaker closest to the house has a black and white wire while the rest just have a black traveling from the speaker closest to the house.
After some googling it I think they wired this in series wiring which is not what I want, rather I want parallel for my use case. I’ll be driving 4 8 Ohm speakers (Polk 90-RT) and fear this is going to result in a loss of sound quality. They are about to close the ceiling tomorrow so I think I need to halt them and have the electrician re-wire the speakers
If it’s a parallel run then I should end up with 4 wires not 2?
Can someone confirm my suspicion / hunch?
