2015 Road Glide Our bag modifications still left plenty of usable space for the client to store things. The Arc Audio amplifier was mounted to a special adapter plate provided by Arc Audio specifically for this bike. The amplifier tucks under the the brain for the factory entertainment system. The Arc Audio Moto speakers fit perfectly in the factory locations. The Arc Audio speakers are designed to allow the factory grills to be used. The fairing stays looking clean and OEM. To make sure the holes were symmetrical we first made a template on paper of where they needed to be. We were careful to make sure that the center hole lined up with the tweeter, so none of the high frequencies were blocked. Our careful planning paid off with a great looking and sounding modification to the bags. The Frogskin mesh protects the speaker from water while still allowing all of the sound to play through it. Our comprehensive audio testing equipment let us see exactly what was happening with the factory equalization.
