Yes, provided the sound bar you are using has either, R/L RCA jacks or a 3.5 mm input jack. If your sound bar only has a mini jack, an adapter kit that converts the RCA cable (the cable coming out of the phonograph) to a 3.5 mm mini-plug is required. This kit is included with the speakers.
Eventually there would be, since nothing lasts forever. The belt resembles a large heavy duty rubber band, which will stretch, or dry out and split eventually. I'm assuming since this model of turntable is so new, the part availability of the belt would be good. ATG
I am not familiar with the Bose sound docks compatibility with this turntable. I recommend that you contact Audio Technica via the following: http://www.audio-technica.com/cms/urls/976a27988bd93712/index.html
