Crown XLS1500 Power Amplifier too powerful for 10 speakers?


Hello Stereophile community!


I am setting up the sound system for a 5000 sq.ft retail store (My first time doing this) and I've picked the following hardware:


*Crown XLS1500 Power Amplifier (300 watts per channel at 8 ohms, 525 watts per channel at 4 ohms, 1550 watts per channel at 4 ohms bridged)


*10 x Yamaha NS-AW150W (6 ohms, RMS: 35W, MAX:120W)


*700 feet of speaker wiring


The installation people did not want to connect the amp to the system saying that the amp was too powerful. However, my original intention was to have the amp be able to support all the speakers since we needed to use a lot of wiring to cover the entire space. I am not looking to blast the space with music. It is just going to be used for some background music so the volume is not going to be turned up at all. 


What do you think? Can I use the amp safely? If yes, how do you think I should do the wiring?


Thank you in advance!

You can either run it through a speaker distibution box or

wire the speakers in a parallel/series configuration.

If you run all speakers off the bridged channel

If you run five off each stereo channel

What will you be using to feed the Crown amp?
