This was a nightmare to install. It should have been simple and easy but it was terrible. First of all 5 1/4" speakers DO NOT FIT! I had to rig up another bracket to make them work and I still have a huge gap on one side. They also aren't really made for 6 1/2" speakers either. I used Rockford Fosgate Punch 5 1/4 in the knee location and Rockford Fosgate Punch 6 1/2" in the sound bar. The screws that were sent, I'm assuming to install the speaker to the bracket, were way to short. They didn't make it through the speaker bracket into this bracket. These brackets looked good out of the box but they just didn't fit either speaker. I'd love to get my money back but I can't send them back because I used them because I was in a time crunch. I do not recommend these brackets at all!
