Transform your classic Porsche 911’s audio system with this precision-engineered speaker adapter plate designed specifically to replace the original mono dashboard speaker with modern stereo speakers.
This custom adapter plate solves the common problem of upgrading your Porsche 911’s dated audio system by providing a perfect mounting solution for 4-inch aftermarket speakers. The plate features precise 102mm speaker holes and an 84x84mm bolt pattern for secure installation that matches your dashboard’s original mounting points.
Whether you’re restoring a classic 911 or simply want better sound quality, this adapter eliminates the guesswork and modification work typically required for speaker upgrades.
