A:
I was told that there could be some interference, but didn't experience any. However, my subwoofer kept shutting down when trying to play music. After two tries with different units, I gave up on the idea. I do not believe using these units side by side was an issue as both were transmitting (at least for awhile). I read in other comments that the subwoofer shuts down because there is not enough base coming from the source. Since I was not out to rock my house, I gave up. Hope this helps.
