For installers, it’s a nightmare being asked to diagnose and solve a problem on a car audio system with terrible wiring organization. Head-units particularly are commonly installed with loose wires, poor connections, and electrical tape around wire bundles that will melt into a sticky mess.
One of the most important things when putting your sound system together is cable management. When installing a head-unit, you need to be sure you have all the proper connectors, ties and tools for a clean looking installation. This can save hours of time in the future.
