Stereo systems differ from mild to crazy, thus installation complexity will vary as well. In a matter of minutes, some side-by-side speakers may be connected. Other arrangements, such as large audio systems, need more complex wiring. It’s good to know how your machine’s electrical system is set up when wiring those sophisticated kits, but it’s not required! Even the most inexperienced off-roader can figure out how to install audio equipment on a quad or side-by-side if they have some simple tools and clear instructions.
