Custom Car Audio/Video System Wiring Diagram - Head Unit, Amps, Subs, LCDs, DVD

This document is a hand-drawn (computer-drawn) mobile audio/video system wiring diagram rather than a factory vehicle wiring schematic. It depicts the layout and interconnection of an aftermarket car A/V installation, including: two front speakers, two LCD screens, a backup or auxiliary camera, a head unit, an equalizer (EQ), a DVD player, a TV tuner, an audio selector, two door speakers, two rear deck speakers, two amplifiers (AMP), a capacitor (CAP), and two subwoofers (SUB). Connections between components are drawn with color-coded lines (red, yellow, magenta/pink, gray, black), presumably representing power, remote turn-on, signal, and ground runs, and several chassis ground symbols are shown. However, the diagram contains no legend explaining the wire colors, no fuse values, wire gauges, connector pinouts, or part numbers, and no year/make/model information. A reader can learn the general signal and power routing concept for a multi-amp, multi-screen car audio/video system, for example, that the head unit feeds an EQ, that source units (DVD, TV tuner, camera) route through an audio selector to the amplifiers, and that a capacitor is placed near the rear amplifier, but not any vehicle-specific wiring details.
