Phoenix Gold ZDC-BMW3

Our ZDC-BMW3 makes it easy to upgrade your audio by integrating seamlessly with our amplifiers. Built for a hassle-free installation, with everything you need included, no cutting or splicing required.

Transform your BMW’s audio experience with the Phoenix Gold ZDC-BMW3 harness, specifically designed for BMW vehicles equipped with the Basic Sound System and with an ASD module. This innovative harness addresses a common issue found in these systems: the front door speakers and under-seat woofers are connected together, compromising sound quality and performance.

In the stock configuration, the small 4” door speakers are forced to handle lower bass frequencies, leading to distortion. Simultaneously, the under-seat woofers are required to reproduce midrange and treble frequencies they were not designed to handle, further degrading the audio clarity. The result? A muddled and distorted sound profile that falls far short of your vehicle’s potential.

Installation

• Disconnect the OEM harness from your ASD module (located in the boot).
• Connect the ZDC-BMW3 cable to the OEM plug, then plug the other end into your ASD module.
• Connect the black ground wire from the harness to the vehicle’s negative battery terminal (-).
• Connect the yellow power wire from the harness to the vehicle’s positive battery terminal (+).
• Plug the ZDC-BMW3 directly into your ZDA4.8* or ZXM400.4ISO* amplifier.

With this quick and easy process, your physical installation is complete, allowing you to enjoy enhanced sound quality and performance.
