Universal Plastic Panel
Some reviews of this indicated it was flimsy and easy to break. Not so. This is strong stuff. I used it to install front speakers in a 98 Audi A4 - which is hard since Audi used custom 3 screw speakers when most all aftermarket at 4 screw. The mounts are also at an angle to the face of the speaker, making it even more difficult. The solution I had got very creative and this product was a huge help. I used a jig saw and dremmel to make the many cuts needed to form the bracket/mount. Great product, and much better than wood that will get wet and rot in your doors.
