Infiniti G35 Coupe 2003-2004 Aftermarket Stereo Dash Kit - Easy

In this review of the Infiniti G35 Coupe 2003-2004 aftermarket stereo dash kit, the bottom line is simple: this kit is for owners who want a clean, plug-and-play way to install a single or double DIN aftermarket radio without cutting factory wiring. The reviewer found the combination of the Metra installation bezel, factory stereo-to-aftermarket harness adapter, and antenna adapter delivers a straightforward installation path. For DIY installers and professional shops that value clear, color coded wiring and a built-in storage pocket, this kit removes the usual headaches of dash trimming and wire splicing.

Key Features

• Metra 99-7604 kit: Provides a single or double DIN dash bezel and trim pieces to hold standard aftermarket radios cleanly in the G35 coupe dash.
• Factory harness adapter: Lets the factory Infiniti/Nissan stereo connector mate to an aftermarket radio harness without cutting or splicing wires, preserving the original wiring harness.
• Factory antenna adapter: Converts the Infiniti/Nissan antenna connector to a standard aftermarket plug so radio reception works immediately.
• Storage pocket: The dash kit includes a neatly integrated pocket below the radio area to store small items and fill the space when using a single DIN head unit.
• Plug-and-play wiring: Color coded and clearly marked wires make matching speaker and power connections faster and reduce the risk of wiring errors during installation.

Who It's For

This kit suits Infiniti G35 Coupe 2003-2004 owners who plan to replace the factory stereo with an aftermarket single or double DIN unit and want a straightforward, factory-like finish. It is aimed at DIY installers and car audio shops that prefer to preserve the factory harness and avoid cutting wires, and who appreciate a storage pocket for single DIN applications.

It is less relevant for owners of other model years, vehicles that require extra modules for steering wheel controls or amplified factory systems, or those who plan extensive dash modification beyond a direct radio swap.
