We just moved into a new house that has in ceiling speakers in multiple rooms. I would like some help on figuring out what components I need, and what options will work the best. First, a bit about how the speakers are wired.
On one wall I have the terminals for all the wires:
Each set of inputs controls one set of speakers in the house:
1) 1) Kitchen – 2 speakers, 6ohms resistance at the speaker wire terminal
2) 2) Deck – 2 spearkers, 6 ohms resistance at the speaker wire terminal
3) 3) Sitting room – 2 speakers, 6 ohms resistance at the speaker wire terminal
4) 4) Office/front sitting room – 4 speakers, 4 ohms resistance at the speaker wire terminal
5) 5) Dinning room – 2 speakers, 6 ohms resistance at the speaker wire terminal
6) 6) Upstairs – 5 speakers, 4 ohms resistance at the speaker wire terminal
7) 7) Basement – 2 speakers, 6 ohms resistance at the speaker wire terminal
8) 8) nothing
I am leaning towards getting at least one, but possible three sonos connects. Ideally, with three I would have one control the basement, one control the deck, and one control everything else. I would like to have these sonos connects run into an amp, at least an 8 channel amp. There are no volume controls for the speakers, so each sonos would become the volume control for the zones. I like having the ability to control the audio with a phone or other wireless device.
Any help on specific amps that would work for this configuration would be very nice. In terms of budget, I would like to spend no more than $700-$800 on an amp. I was looking at a Niles SI-1230 series 2 120channel amp because they are on sale at amazon, although I think 12 channels is probably more than I need. Addtionally, I do not believe I have the option to bridge any channels as the most resistence my channels see is 6 ohms, is that correct? Is there an equivalent 8 channel amp? How is the Russound R850MC 8 channel amp for what I need,, it looks like it has 8 channels, but only 4 zones and I don't know if it can send a mono (l+r) signal to each of it's channels.
Additionally, would this setup work, some number of sonos connects, into an 8 channel amp, with no other equipment? Are there better options out there I have not considered? Any help would be appreciated.
