This details the installation of Motorrad Audio's Subwoofer Upgrade Kit. This is the subwoofer portion of our upcoming Stage 5 and 6 Packages for the K1600B & Grand America. Where our other stage kits will give you plenty of output for hearing your music on the highway, due to space constraints they can't play at high volume with bass. This kit fills that void with dual 8" AudioFrog subwoofers and a JL Audio amplifier. https://www.motorradaudio.com/collections/bmw-motorcycle/products/subwoofer-upgrade-package-for-k1600b-grand-america #k1600 #bmwmotorrad #motorrad #k1600b #k1600ga #grandamerica #motorcycle #bmwk1600b #motorradaudio #extremeaudiova
