Exclusively available through an authorized Yamaha dealer.

Building off of the Premium Top Audio Starter System, this expansion kit provides four additional speakers and mounts needed to install on your Wolverine X4’s Premium Headliner (sold separately). That makes a total of six speakers for a louder, cleaner sound even in the dirt and mud. No need to have the local audio cut and spliced in a system. True plug-and-play installation will get you out on the trail faster.

Kit includes:
- Four additional SSV Works® A6 Powersports 6.5" marine-grade speakers provide an amazing combination of clarity and volume along with the durability you expect
- All necessary hardware, wiring, and harnessing needed for installation
- Requires Premium Top Audio Starter System by SSV Works®, sold separately
