I have installed the speakers in my Motoradhelm and am very satisfied. The capsules I have completely taken out of the "Packaging", the very friemeligen wires with a little hot glue and then additionally secured could the capsules in a precisely matching depression (where the buckle attached) in this space. The top cover has Velcro and was gebappt about the whole thing afterwards. The cable I have shortened and connected directly to a Bluetooth receiver (). For Navi's always enough; for music, the helmet is too loud. Since the capsules have naturally little coverage to make sure that the capsules sit in exactly the right position and symmetrical. Just as the sound comes after exactly from the middle. Test before bonding is essential.
