power/iphone 6 connection

I finally got the speakers connected to my iPhone6, but no sound. I turned off speaker remote to start over, and the power won't come back on. I changed outlets, turned off bluetooth on my phone, nothing, no matter how long I hold down power button. The only thing I changed was unplugging the AV cord to the woofer....it wasn't connected to anything and I couldn't figure out what it was for. These speakers seem to be way more trouble than they are worth! And customer service isn't open on the weekends.
