In my bathroom, I have a pair of 4 ohm (in the shower) and a pair of 8 ohm in ceiling speakers (above my sinks). The shower has a glass door to the ceiling, so I wanted to be able to listen stereo sound while at the sinks and while in the shower.
The 2 channel amp I plan on using has a minimum impedance of 4 ohms/channel (Sonos Connect:Amp).
It doesn't appear I can wire them in parallel, because the 8 ohm and 4 ohm load would lead to an impedance of 2.67 ohms/channel, and the minimum is 4.
Would I be able to wire it in series? I wasn't sure if there would be a problem combining speakers with different impedance? Any help would be appreciated.
In order to clarify, I would run a wire from the (+) terminal of my left channel to the (+) of the 4 ohm speaker, then from the (-) of the "left" 4 ohm to the (+) of the "left" 8 ohm speaker, then from the (-) of that speaker to the (-) terminal on the amp.
It is my understanding that this will create a 12 ohm impedance load. Would it make a difference if the speaker above the sink was a single stereo speaker instead of 2 mono speakers? Thanks!
