I have (2) 130 RMS Speakers & 2 150RMS Speakers both 8 ohm. I want to connect these to the Sonos Amp in parallel. Is the Amp powerful enough to handle this load?

Matching speakers to Amp

From the Sonos Amp FAQ:
Is the 125 W/channel a peak rating or rms/continuous?
Amp provides 125W continuous average power sine wave, into an 8 Ohm load, both channels driven.
If your speakers are 130 and 150 RMS, I would think it would be best to get two Amps - one to power each pair of speakers.

Hi
The Sonos User Guide says it is possible...but I’d suspect the speakers need to be identical in specs. You might contact Sonos Tech support for a definitive answer.
I guess what I’m asking is the amp under powering the speakers? It seems not to be powerful enough and will that impact the sound? If (2) 8 ohm speakers are connected in parallel then they would become 4 ohm at the amp I believe (8ohm/2 speakers =4ohm). If the amp is good for 200w @ 4 ohm I believe the speaker would be under powered in this case (150w*2 (speakers per channel)=300w*50% (greater power then the speaker)=450w needed per channel. Please let me know if I’m not doing something correctly here but that’s what I gather.
