Product Research


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 will 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.

How thick is the adapter?

I can't remember, but make sure the speakers line up with the mounting holes. I had to modify and drill extra holes in the door.

This will depend largely on your vehicle. For details on installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on what you will need for an installation.

Thanks for your question. Yes both the mounting brackets and speaker harnesses are two per package. Hope this helps.
