The MXASB9 Compact Powersports Soundbar was designed specifically for use on personal watercraft machines and powersports vehicles. This powered speaker is IPX7 rated meaning it is able to withstand full submersion making it ideal for use on the lake or in the mud. The multi-functional mounting bracket provides multiple mounting options allowing you to bring big Memphis sound anywhere you go. The MXASB9 features Bluetooth controls permitting you to store your device in a dry bag while retaining control of your music. If you have a Yamaha WaveRunner that needs an audio upgrade, pair this unit with the YAHFXBRK bracket which will allow the unit to mount onto factory Yamaha WaveRunner mounting locations.
