RED WOLF Front/Rear Door 6.5" Inch Aftermarket Speaker Update Install Speaker Adapter Bracket Spacers for Chevrolet 2006-2021, GMC 2006-2020, Some Cadillac, Buick, Pontiac

Used these on my 2009 Hummer H3. They fit well and seem to have durable construction. I added a bit of foam tape to the back to ensure nothing would rattle. They don't come with any screws for mounting the speakers and some speaker kits only come with really long screws. Keep that in mind. You may need to order your own shorter #8x1/2" screws if mounting without using a speaker grille.

Solid adapters. Much more sturdy than the metra ones

Perfect fit for 06 impala.

Would probably fit a 6” better than a 6.5” speaker. Other than that good quality.

Worked great, very solid and thick. Should last a while, I bought this set and the Kosche brand set to compare the two and this one was night and day difference, much better quality.

Solid build quality. I was actually pretty impressed by this. It's funny because there was a bit that was broken but as a whole it's sturdy.

The item description is wrong. It does not fit a 2004 GMC Yukon with Bose speakers.

Perfect fit to 2028 z71
