BMW Z4 Hi Fi AMP Connector Harness

Description

BMW HI-FI amp connector harness for upgrading to aftermarket amplifier in Z application.  Please note this amp connector harness will only work with OEM 42-pin Hi-Fi AMP connector and will not work on vehicles equipped with Harmon Kardon (HK) sound system.  It is designed for plug-n-play application without cutting or splicing factory wiring harness for installation of aftermarket amplifier(s).  Please verify that the attached pin out diagram matches your vehicle. All wires are thin-walled automotive wire specification meeting or exceeding OEM wire size, 18 AWG for all signal and output wires and 12 AWG for subwoofer output wires.  Signal wires are equipped with high quality gold plated metal male RCA connectors, not the cheap plastic one.   All wires are crimped and soldered to ensure secure connection.  All wires are labeled and come with connector pins assignment documentation.  Power and ground connections are not included since most aftermarket amps require higher current beyond the amperage provided from the factory connector.
