A:AnswerI'd have to say no. The Yamaha minimum impedance is 6 ohms. The JBL set looks like it's 4 ohms.
Too low an impedance will result in weak output and poor tone.
A:AnswerOn the receiver select Bluetooth as the current input. On your phone make sure your Bluetooth is enabled and have it search for a connection. The two devices should recognize each other and your phone should connect.
A:AnswerMerciellus, you will connect your cable box to the hdmi inputs on the receiver. Do the same for your blu Ray player, video game system, roku system, etc. You can connect by HDMI or by the red, yellow, white A/V cables. Those will have a lower quality image and sound quality though.
Then connect another hdmi from the tv to the hdmi port on the receiver. This will allow you to play all your devices you connected on the inputs through your tv.
