Home stereo system

Hi..
I do have ONKYO TX-8270 , 100 watts and separated 6 zone switch. I’m planning to install  8 ohm ceiling speakers in all rooms, my concern is does the speaker watts matter here, is it suppose to match the amp. Wattage, one Of the zones needs 4 to 6 speakers, can I do that? Thanks

You'll need additional power if you're going to run that many speakers.

You are potentially looking to run 16 speakers of 1 domestic hifi amplifier. You really need to rethink your plans

100v PA Speakers and Amp as used commercially Would do the job.

The question is do you want the sound simultaneously in all the rooms or are you happy to  have the ability to switch the sound to any room?. This latter is within the capacity of any electrician
The other answers have focused on the first option,and have indicated the difficulty...
But there are plenty of other ways of achieving that goal.  Active speakers ,which include amplifiers and speakers within the cabinet ,and can be wirelessly or wire connected to the  music source will also work. Depending on quality,they are available from about 100 quid a room.
