A:AnswerHi, Justin.
This Soundbar is not compatible with Echo Dot. If you would like to pair to a stereo set up it would be with the cord provided or through Bluetooth.

A:AnswerIf your TV has rca jacks it will work on your TV. It comes with an adapter to work on TVs with RCA jacks. Plug in the soundbar and hook it up to your TV and enjoy your entertainment!!
A:AnswerSorry to say I also have problems with sound quality if I use this for anything but low-to-moderate volume. I reached out to Insignia's tech people, asked if there was a driver issue, or perhaps an update. They said no. I'm actually considering replacing mine altogether.
