Powering nine home speakers

jj91709,

     Do you have a 7 channel Onkyo amp or receiver? 

     Do you just want music that can be played louder through the 9 speakers in your room?

    Are these speakers stand alone regular speakers or are they mounted in the wall or ceiling?

    What is your budget?

All 9 are installed in the ceiling. Goal is just more power going to the 9. The amp is 7.1 capable but the total wattage is insufficient to drive all 9.

     Okay. 

     You can connect the left and right front outputs on your receiver to a separate multi-channel amp.  This allows you to connect some speakers to the speaker outputs on the Onkyo receiver and the remaining to the multi-ch amp's speaker outputs. Whatever source you select on the receiver will play through all speakers.

     You didn't state your budget and there are many types of multi-ch amps with a wide variety of channels (3 channels plus), a wide variety of watts per channel and a wide range of prices.  I'd recommend matching the watts per ch on your multi-ch amp to the watts per ch on your receiver.  If all your speakers are all the same brand and model, this means they'll all have the same efficiency rating (listed as decibels at 1 watt).   This means each speaker will be producing the same volume output at any setting your receiver's volume knob is set at.  

     Just google "multi-channel home audio amps" if you'd like to see the various amps available.

Trade in the Onkyo and get this.

Well if this is a stereo set up, then your answer is to do more of a pro/distribution type setup.

If you are using this for movies, why oh why do you have 9 speakers in your ceiling??
