2019 BMW K1600 Grand America The left side speaker has been upgraded in this photo. Our custom adapter plates allowed the speakers to fit in the factory location. Waterproof gaskets were used for the wires running into the storage area. Thanks to our careful work the factory grilles fit over the speaker upgrades. The grilles that come with the overlays were used. The rear bag overlays provided the perfect solution for this BMW. The small size of the Rockford amplifier allowed it to easily fit in the bike. The rear speaker upgrade looks and sounds great! The new speaker adapter was cut on our laser cutter.
