The DB Drive sound bar adapter will allow for upright mounting on ATV or UTV. This is a Marine sound bar with the mounting Utility rail on top of the bar. Therefore, it will mount up side down without the adaptor. This adaptor is not required for the Polaris High Lifter mount or when used with the bar mount included with the bar. For the Can Am Outlander, you will need the adapter and a Rage Outlander mounting bracket set. Comes in Black to match the Sound Bar.
