quality is fine and fits perfect. alsof in the front and rear of a Mazda 2/Demio. isolation foam of anything like it is recommended for the back side when mounting the rings.
Fits perfect to my rear door speakers in Mazda 3 (Axela) 2015. Good quality of ring bracket, cables and connectors also fits perfect to originals. I had to make hole for cable, but it is easy to do. Package could be little better. Thanks for fast shipping.
