This 1985 advertisement is for a high fidelity motorcycle sound system called the Audio Cannon. It attaches to your motorcycle handlebar and is shaped some what like a box, as you can see in the ad. I don't think it ever caught on because this is the first time I have seen anything like it. It looks like it blocks the rider from seeing the instrument cluster, which could be the main reason why it flopped. Can't blame them for trying though.....You can't catch a fish unless you cast the line.
