Alpine Head Unit Wiring Diagram - Wire Colors, Speaker & Amp Connections

This document is a wiring/connection diagram page from an aftermarket Alpine car stereo installation manual (compatible with the KCE-400BT Bluetooth interface and an Ai-NET CD changer). It was uploaded to a 1996 Ford Bronco gallery, presumably documenting the head unit installed in that truck. The diagram lists the head unit's wiring harness color codes in English, French, and Spanish: Blue (power antenna), Blue/White (remote turn-on), Pink/Black (audio interrupt in), Orange (illumination), Red (ignition), Yellow (battery, with a 10A fuse), and Black (ground). Speaker wiring is also detailed: Gray/Gray-Black for right front, Violet/Violet-Black for right rear, Green/Green-Black for left rear, and White/White-Black for left front, with polarity markings. Additional connections shown include a USB cable to iPod/USB memory devices, an Ai-NET cable (included with the CD changer), an RCA extension cable (sold separately), a NORM/EXT AP switch, and RCA pre-outs to separately sold amplifiers driving rear, front, and subwoofer speakers. The right side illustrates connections to the vehicle antenna, power antenna, amplifier/equalizer, vehicle phone, instrument cluster illumination lead, ignition key, and battery. A footnote notes the system selector switch is located on the bottom of the unit.
