METRA 82-5600 speaker adapter plate 5.25 6.5 to 6x8 car electronics accessory

5.25 / 6.5 Inch Speaker Adapter Plate

The Metra 82-5600 adapter plate lets you mount a 5.25 inch or 6.5 inch speaker into a factory 6 x 8 inch opening. It is designed for car audio installers and DIY enthusiasts who want a clean fit without custom fabrication. The part simplifies speaker replacement while maintaining a professional appearance.

Adapts Factory 6x8 Openings For Aftermarket Speakers

This plate replaces improvised brackets or ill-fitting spacers when upgrading door or rear-deck speakers. The jump is worth it when the original holes are 6 x 8 inches and the new drivers are 5.25 or 6.5 inches, eliminating gaps and reducing vibration. It is not for installations where the factory opening already matches the speaker size or where a different bolt pattern is required.
