Summary: Stay away from this product! I am on my second one the 1st only lasted 3 weeks before it shut down and then there was no volume. I sent it back and received another one over night from Amazon. I plugged in all speakers as per instructions, turned on by sub woofer and it shorted out my $700.00 sub. I spoke with a guy named Frank at Yamaha because the wifi wouldn't work, and there is not much volume.That was a waste of time, what a rude pompous ass he was.
