A:AnswerI think you may need to buy the mounting brackets for connecting the soundbar to the underside of the tv. I haven't received any mounts for that along with the soundbar.
A:AnswerWould not know if you can hang the sound bar to the bottom of a TV. However, the box comes with an optical cable and power cord so basically you're good to go.

A:AnswerYes, the speakers will connect to the Soundbar. In order to use Bluetooth wireless technology, devices must be able to interpret certain profiles. This unit is compatible with following profile: A2DP (Advanced Audio Distribution Profile); Codec : SBC, AAC. ^Daphane
A:AnswerThe soundbar does have AUX In (3.5mm). This unit will turn itself off to save electric consumption if the main unit is not connected to an external device and has not been used for 15 minutes. ^Daphane
A:AnswerFor best performance of wireless connection such as Bluetooth, do not install the unit on Metallic furniture because wireless connection communicates through a module positioned on the bottom of the unit. ^Daphane
