I have 4 nice Polk Audio 6.5 inch speakers from a previous vehicle. I would like to put them in the 4 doors of my 2021 Blazer with the base stereo. The rear doors have this size speaker and available after market brackets. The front doors apparently have 6x9 mounting locations. There are 6x9 to 6.5 inch adapter brackets out there but I don't see any for this vehicle. Anyone know of one that will work or other method of installing 6.5 inch speakers in the front doors? Thanks in advance, Rob.

Hello I know this is late. I ran into the same issue. My solution to the problem was I bought the Metra 82-3019 mounting bracket it is for the camaro but they will fit the blazer. I also purchased the Metra 82-6901 and the Scosche SA69 the first one has the option to add tweeters. I had to do some custom cutting of the 6x9 bracket about 1/4 th of an inch I then used adhesive to mount either of the 6x9 to 6.5 adapter plates to the adapter and a little routing to even it out I then mounted the 6.5 in the bracket mounted to the door check to make sure the window donot hit the speaker and make sure the door panel goes back on. Added some fast rings for the speakers made the connections to the existing wire using these adapter plugs American international SH3802 wiring harness and was able to finish the job. If you donot make modifications to the adapter and add the 6x9 to 6.5 to the adapter the door panel will not go on all the way. I know it is alot but sharing what I did. The the other route is to get them custom made but that is to much. Also if you want to replace the dash speakers

They are 2 3/4 of an inch speakers that will drop right in. All this can be bought from Sonic Electronix Best Buy Amazon between 10 to 17$ each they both come in pairs for the bracket and the adapter. I hope this helps.
