More details on the Metra 82-7501 Speaker Mounting Brackets

Pat M.

Product Research


Overview: The 82-7501 is designed to allow easy replacement of factory speakers with select aftermarket 6-1/2 and 6-3/4 speakers. Please enter your vehicle information to confirm fit. 5-1/4s will also fit, but not well, so they are not recommended.

6-3/4 Speakers: For a 6-3/4 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.

6-1/2 Speakers: 6-1/2 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).

5-1/4 Speakers: While a 5-1/4 speaker will mount easily in this bracket given the bolt pattern, the frame of a typical 5-1/4 is approximately 1/2" smaller than the opening in the bracket, making a 6-1/2 or 6-3/4 a better fit. When using a 5-1/4, a speaker baffle must also be used to seal the rear of the speaker.
