This forum is dedicated to helping people with questions about installing radio equipment in vehicles. This can include antenna installs, electrical wiring questions/problems, and mounting systems. Pictures of installs are welcome.
Note: Discussions regarding lighting, sirens, and other equipment now has its own forum in the 'off-topic' section below.
