Hello AVS 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!

If anything, I would think not powerful enough. Someone with more experience will weigh in on it soon, I would think. In general, it was probably a good decision not to hook them all up to 2 channels, but "too powerful amp" is just about an oxymoron.
I guess it depends on how you would hook them up. All in parallel would be bad, all in series would probably work but not get to high volumes. A combo of P/S would probably get you somewhere you could live with it and be safe, but I'm too lazy to do the math. Perhaps they were too lazy to do the math too.
700 feet? That is a long run. What AWG wire were you trying to use?
And, that amp seems to have gain control on it (i.e. attenuators or volume control), so you should be able to throttle it down if it were truly too powerful.
Did they try to sell you a different model amp? One that is less powerful and that they "just happen to have in stock". If yes, then if it were me, I would be done dealing with them.
