METRA 82-7400 6"-6.75" Speaker Adapter Nissan Infiniti 2000-up

METRA 82-7400 Speaker Adapter

The Metra 82-7400 is a pair of speaker adapters designed for select Nissan and Infiniti vehicles from 2000 onward. They allow the installation of aftermarket 6in to 6.75in speakers into the factory mounting locations. The break-away tab design provides flexibility for both front and rear door applications. These adapters bridge the gap between factory wiring harnesses and new speaker terminals.

Who It Suits

This kit suits owners of compatible Nissan or Infiniti models who want to upgrade factory speakers without cutting or modifying the original door panels. It is ideal for a straightforward speaker swap using standard 6in to 6.75in aftermarket units. Installers who need to retain the OEM look and mounting points will benefit from the precise fit. Buyers with vehicles outside the listed application range or those requiring adapters for different speaker sizes should look elsewhere.

Build Integration

The two adapters mount directly into the existing speaker openings using the factory screw holes. No additional brackets or fabrication are required for a secure fit. The break-away tabs can be removed to accommodate specific front or rear door depths. This design frees up the installer from running new wires to the factory harness connectors. The package includes both adapters needed for a standard pair installation.
