Greatly underused material in car audio fabrication, sheetmetal is probably one of the best materials to create OEM quality brackets and mounts. In a recent installation, I was presented with a high-end car needing a remote-mounted radar detector. The goal was a stealthy install with no permanent modifications to the vehicle. In this type of installation, the radar receiver is mounted behind the grille or front bumper fascia. Unfortunately, this particular car offered no location that was optimum for stealth, proper signal reception and mounting depth. I came up with an innovative solution by using the properties of sheet metal.
