Wiring and Connections ● We recommend wire-to-wire connections such as power, ground and speaker wiring are soldered and protected with either heat shrink tubing or high quality electrical tape. ● The main (yellow) power wire should be connected to a source with at least 10 amps of additional current capability to support the unit.
Rear Mounting Instructions ● Check for appropriate mounting depth and mechanical or electrical obstacles behind the mounting panel BEFORE any cutting. Including the “U”-shaped aluminum mounting bracket, at least 4” (100mm) depth is required. ● Using a 3” hole saw or air saw, cut a 3” (76.2mm) diameter hole in the mounting panel. Use a file or sandpaper to smooth out any rough edges after the cut is complete.
Front Mounting Instructions ● Check for appropriate mounting depth and mechanical or electrical obstacles behind the mounting panel BEFORE any cutting. At least 3.75” (95.25mm) depth is required. ● Using a 3” hole saw or air saw, cut a 3” (76.2mm) diameter hole in the mounting panel. Use a file or sandpaper to smooth out any rough edges after the cut is complete. ● Remove the snap-in covers on the front panel hiding the mounting holes.
