I have a SONOS CONNECT connected by RCA jacks into a NILES SI-2100 100 watt amplifier. Both devices are in my detached garage and feed four Niles RS6 8 Ohm speakers that are around my pool. In between the two pair of speakers and the amplifier i have TWO impedance matching volume controls mounted on my external garage wall. I can control the volume of the two pair of speakers while outside. The configuration has worked well over the past 3 years though i’ve had issues with heat and amplifier clipping at higher volumes - especially on hot days. The sound quality is fair but acceptable for an outdoor landscape.
The question i have:
I just purchased two additional 8 Ohm speakers for a smaller patio next to my pool area and i’m trying to figure out the best way to supply power. I was thinking of purchasing an additional NILES SI-2100 (they are running at ~ $350 now) and having that amplifier just run the new speakers using one of the impedance volume controls already mounted to just control those two new speakers. I would control the original four speakers with the other impedance volume switch using the original amp. I would have to rewire the configuration but i have no problem with that. I would also have to split the RCA signal from the SONOS to the two amplifiers. There is no optical in on those amps so not sure about the sound quality.
Or is it better if i somehow daisy chain the two amplifiers and have them supply power to the now six speakers. I can of like the idea of having independent volume control for the two new speakers and keep the 4 pool speakers by themselves.
Planning on wall mounting a fan or perhaps purchasing an AIRCOM S7 component fan to help with the heat issues.
Any suggestions or guidance would be much appreciated
