Features

Overview: As of 9/17/19, the 82-7401 is compatible with select Infiniti vehicles. The bracket is designed to allow easy replacement of the factory speakers with select aftermarket 6½ or 6¾ speakers. (Please enter your vehicle information to confirm fit.)

6¾ Speakers: For a 6¾ speaker to fit in the opening of this bracket, the tabs around the inner speaker opening need to be removed. They are scored along the bottom for easy removal, but still may require pliers and a file.

6½ Speakers: 6½ speakers with the 3-hole or 4-hole bolt pattern can be mounted using the tabs around the inner speaker opening of this bracket (if the hole spacing matches).

5¼ Speakers: While many 5¼ speakers will mount in this bracket given the bolt pattern, the frame of a typical 5¼ is smaller than the opening in the adapter plate, making a 6½ or 6¾ a better fit. When using a 5¼, a speaker baffle must also be used to seal the rear of the speaker.
