Select Increments Versa-Pods
Crutchfield Customer Review (What's this?)
used these to mount 4" speakers on top of the dash in my Polaris Slingshot. I wanted speakers mounted up high and aimed somewhat towards my head due to the rampant wind noise associated with the Slingshot's open cockpit. The Versa-Pods were the most compact speaker enclosures I could find and fit below my line-of-soght while placing the speakers in a good position to beam sound towards the occupants.
