The Custom Autosound kit includes fasteners for hard mounting of the receiver unit to your mounting location. We decided that a trip to the hardware store for industrial strength Velcro might make for a suitable alternative mounting arrangement. The hook side of our Velcro made a solid grip on the carpeting during our testing and we decided that this was the way we would go for mounting the unit. Affixing two large pieces to the underside of the case got the job done and keeps the unit in place easily. After orienting the receiver so that the accessory plugs faced forward we accomplished the final positioning of our Secretaudio unit.
