Metra 82-3300

Metra's 82-3000C brackets will allow you to install select 5-1/4" or 6-1/2" speakers in the factory speaker openings of select 1995-05 Chevrolet and Pontiac vehicles. Please enter your vehicle information or call an Advisor at 1-888-955-6000 to confirm that these adapters are compatible with your vehicle. Warranty: 60 days.

Important Note: Some 6-1/2" speakers use a larger frame and require a larger cutout. We call these 6-3/4" speakers, and they won't fit in this bracket. This bracket will only work with speakers that require a cutout diameter of 5-1/8" or less.

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.

I installed these in my 2002 pontiac sunfire. The passenger door fit great with it, however the driver door was a different story. After the struggle and my door not screwed in the way the installation was complete.

Crutchfield Customer Review (What's this?)

It did not work for my car. 2002 Pontiac sunfire as it had six speakers not 4 tweeter up front with the other speaker. Now I have to make a board about 1/8 thick and mount it to that and then to the car. have not had time yet but not a big thing for me. Other than the time I wasted trying to get it to work with the hardware recommended

Crutchfield Customer Review (What's this?)

I like this product because it fits both the speakers and the car and is easy to attach. The only problem I have is that its slightly too large in depth for my door panel to fit over it, which is disappointing as Crutchfield told me it would fit my car no problems.

Mounted in 01' Cavalier
Worked perfectly Wtih 6 1/2" Pioneer speakers...
Didn't try grills but it fit fine without, good thing you don't need them...??

Ran battery down while installing full system, speakers sounded blown with low batt.
Sent speakers back to find out nothing was wrong
Must have fully charged system to get right sound

I got these to install Infinity 6020cs speakers in my 98 Cavalier doors. Using these adapters I had a major clearance issue with the door panel. It would have been necessary to cut out the panel and use the grille from the Infinity speakers which I did not want to do. I ended up using these adapters to trace a template on 1/4" plywood, so they did serve a purpose and helped me with the install, but not as they were intended. These need to be about 1/2" thinner and they would have fit without issue. I would return them but it is not worth paying the shipping to do so.

Nice if you don't mind modding a bit.

I bought these to install in the front door of my 2004 Grand Am. I was sorely disappointed when trying to install 6.5" speakers from Rockford Fosgate, the mounting hole was too small!? I had to modify these to hold my speakers by hollowing out the center a bit. It wasn't too hard just very annoying that the speakers did not fit in from the Metra factory. Probably a great product for 5.25" though.

I gave this product 3 stars because it has worked well other than the aforementioned pain.

Overview: As of 11/17/14, the 82-3300 is compatible with select 1995-2005 Chevrolet and Pontiac vehicles.

(Please refer to the Crutchfield Vehicle Selector to confirm fit in your vehicle.)

6-1/2 Speakers: 6-1/2 speakers with the 3-hole bolt pattern or the symmetrical 4-hole bolt pattern can be mounted using the tabs around the inner speaker opening of this bracket (if the hole spacing matches).
