More details on the Metra 82-9101 Speaker Mounting Brackets

Product Research


Overview: As of 10/4/18, the 82-9101 is compatible with select 2007-2011 Audi A6 and S6 models. The bracket is designed to allow easy replacement of the factory speakers with select aftermarket 6-1/2 or 6-3/4 speakers. (Please enter your vehicle information to confirm fit.)

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 a 3-hole bolt pattern, Ford 4-hole bolt pattern, or symmetrical 4-hole bolt pattern can be mounted using the tabs around the inner speaker opening of this bracket.

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.
